Sixty eight chickpea cultivars of India belonging to both Kabuli and Desi types were studied for the diversity using 60 RAPD primers. Among them 50 were found to be polymorphic. On the average 3.55 loci per marker was found for the entire population of 68 cultivars. Based on the banding pattern, the cluster analysis was done using UPGMA and the dendrogram was prepared. The similarity coefficient ranged from 0.71 to 0.90 among the genotypes. The PCA analysis also supported the finding from the dendrogram. It was found that the desi and Kabuli types did not segregate into two distinct groups which indicated that perhaps very few genes were responsible for the differentiation of chickpea in to Desi and Kabuli types during their evolution. In order to broaden the genetic base of the chickpea germplasm of India, efforts should be made to utilize the exotic germplasm and the wild relatives.

A field experiment was conducted during winter season of 2003-06 at Almora, Uttarakhand to evaluate the productivity, profitability and energetics under different weed management practices in wheat (Triticum aestivum L. emend Fiori & Paol). Two improved intercultural tools viz., wheel hoe and long handle khurpi along with tank mix isoproturon (0.75 kg/ha) + 2, 4 D (0.5 kg/ha) and farmers' practice (2 manual weedings with kutla at 30-35 & 55-60 days after sowing) were studied for their effectiveness as compared to a weedy check management practice. The maximum decrease in weed population (86.9%) and weed dry matter (78.8%) was recorded with isoproturon + 2, 4-D application. However, it failed to enchance wheat productivity markedly over farmers practice. Net return and B:C ratio were significantly more under weed management through isoproturon + 2, 4-D, however, energy use efficiency was highest under long handle khurpi.

A field experiment was conducted during 2005-07 at Almora, Uttarakhand to evaluate the effect of different organic manures (farmyard manure, poultry manure and vermicompost) and biofertilizers [Rhizobium leguminosarum + phosphorus-solubilizing bacteria (Pseudomonas sp.)] on yield of organically, grown garden pea [Pisum sativum subsp. hortense (Neilr.) Asch & Graebn] and on soil properties. Pod yields for all the treatments were significantly higher than the control. In both the years, application of farmyard manure 10 tonnes/ha + poultry manure and vermicompost each 1.5 tonnes/ha + biofertilizers gave the highest pod yields (7.02 and 7.52 tonnes/ha) and it was significantly superior to other treatments except farmyard manure 20 tonnes/ha + biofertilizers and application of farmyard manure 10 tonnes/ha + recommended NPK (20:26:33 kg/ha) through fertilizers. Application of farmyard manure 20 tonnes/ha + biofertilizers resulted in the lowest soil bulk density (1.19 Mg/m3) compared to other treatments. The soil pH increased in all the treatments compared to control. Similarly, soil organic C was significantly higher in all the treatments (1.21-1.30%) except in poultry manure 5 tonnes/ha + biofertilizers compared to control (1.06%). Application of farmyard manure 10 tonnes/ha + recommended NPK, however, recorded significantly higher available N than plots under organic manures. Application of farmyard manure 10 tonnes/ha + recommended NPK being at par with application of farmyard manure 10 tonnes/ha + poultry manure and vermicompost each 1.5 tonnes/ha + biofertilizers registered significantly higher available P and K contents in soil compared to other treatments. Application of farmyard manure 10 tonnes/ha + recommended NPK gave highest net returns (R 63 295 /ha) compared to other treatments. However, all organic treatments except vermicompost 7.5 tonnes/ha + biofertilizers gave higher net returns (R 64 148 - 75 498/ha) than application of farmyard manure 10 tonnes/ha + recommended NPK, when a price premium (10-15%) was assigned to organic garden pea.

Maize is an important food and feed crop worldwide. It occupies 144.4 m ha globally with a production of 695.2 m tones. The area under maize in India is 7.6 m ha with a production of 14.7 m tones. The essential amino acids like lysine and tryptophan are in reduced quantities in maize. In this context, the story of quality protein maize (QPM) assumes significance. The protein profile of QPM maize is 90% of the milk protein. CIMMYT, Mexico playeda significant role in the development of QPM maize. This achievement at CIMMYT paved the way for the transfer of QPM traits to other local/regional inbreds, composites and the synthetic cultivars. Many Asian, African and South American countries including India, China, Mexico, Ghana, Peru and Brazil have commercialized QPM cultivars. Globally QPM occupies 9.0 million acres. India released many CIMMYT QPM hybrids viz., Shaktiman 1, Shaktiman 2, Shaktiman 3, Shaktiman4, HQPM 1 and HQPM 5, besides few composites. The second jump for the development of QPM hybrids took place in India by developing short duration single cross QPM hybrids by converting the non-QPM inbreds in to QPM by employing marker assisted selection (MAS). This approach saves time and cost for the development of QPM inbreds and hybrids. Following this approach, Vivek QPM 9- a single cross short duration QPM hybrid from VPKAS was developed and released in 2008. This is not only has a better nutritional profile, but also rich in iron and zinc content. QPMmaize will help in ensuring the food and nutritional security of the Indian population.

Turcicum leaf blight (Exserohilum turcicum) is the most common and chronic disease of maize, especially in Himalayan hilly region. Studies on inheritance of the disease were conducted using six generations derived from 4 susceptible (CM 128, V 327, V 128 and V 17) and 2 resistant inbred lines (V 335 and V 13) having early maturity suited to hilly region. The 6 parents and their 15 F 1's, 15 F 2's, 15 BC 1's and 15 BC 2's, were studied for reaction to turcicum leaf blight at 2 locations namely, Hawalbagh Research Farm of Vivekananda Parvatiya Krishi Anusandhan Sansthan, Almora during kharif 2000 and at Sihora Farm, Rudrapur during rabi, 2000-01. Significant additive and dominance variances were observed in most of the crosses in the two environments mentioned above. The study suggested that both additive and dominance components were important in the inheritance of turcicum leaf blight, the magnitude of additive component being relatively higher than non-additive component. Gene interactions and environment were also found to be important. The resistant lines V 335 and V 13 were found to be the best general combiners. Highly significant SCA effects were observed in both environments in 3 crosses, viz. V 327 × V 335, V 335 × V 17 and V 13 × V 128, which involved one disease resistant parent. Significant GCA and SCA variance also indicated that the additive and nonadditive components were important in the inheritance of resistance to turcicum leaf blight in maize. Low to high Hns estimates were observed with good genetic advance, especially at Hawalbagh during kharif 2000. The higher estimates of additive component of variance, heritability and genetic advance during kharif 2000 indicated that selection for turcicum leaf blight resistance was likely to be more effective at Hawalbagh during kharif than at Rudrapur during rabi. Population improvement approach, preferably, reciprocal recurrent selection may be followed for the development of early maturing and turcicum leaf blight resistant cultivars of maize, especially for the Himalayan hilly region.

An on-farm trial was conducted at five farmer fields of Bageshwar district of Uttrakhand to validate, refine and popularize the technology developed by VPKAS, Almora for managing Buttercup (Ranunculus spp) during 2007-10. The aim of the study was to find out the effectiveness of 2,4-D @ 1.0 kg ai/ha, isoproturon @ 1.0 kg ai/ha and tank mix application of 2,4-D @ 0.5 kg ai/ha with isoproturon @ 1.0 kg ai/ha over farmers practice of hand weeding twice at 30 and 60 DAS and unweeded control on the infestation of weeds and profitability of wheat (Triticum aestivum L. emend. Fiori and Paol.). Tank mix application of 2, 4-D+isoproturon (0.50+1.0 kg/ha) at 35-40 DAS reduced the density and dry weight of Ranunculus and other weeds and nutrient uptake by weeds (3.9 kg N, 0.9 kg P and 6.2 kg K/ha) compared to farmers practice. This combination also resulted in 12.5% higher grain yield, nutrients by wheat (73.5 kg N, 11.6 kg P and 60.0 kg K/ha) and net returns (r 19 030/ha) With this technology, drudgery reduction of about 475-man days/ha can be made possible, which could be used in other fruitful activities of hilly farmers, particularly women.

Pusa RH10, a popular high yielding superfine grain aromatic rice hybrid and its parents Pusa6A and PRR78 are highly susceptibility to blast disease. Marker assisted backcross breeding (MABB) approach was employed to incorporate blast resistance genes viz., Piz-5 and Pi54, from the donor lines C101A51 and Tetep into the genetic background of PRR78 to develop Pusa1602 (PRR78+Piz5) and Pusa1603 (PRR78+Pi54), respectively. Foreground selection for the genes Piz-5 and Pi54 was effected using tightly linked molecular markers, AP5930 and RM206, respectively in two independent backcross series. Further, foreground selection was coupled with stringent phenotypic selection for agronomic, grain and cooking quality traits, to accelerate recurrent parent phenome recovery. Five superior BC 2F 2 plants homozygous from each of the backcross series were selected and advanced to BC 2F 5 generation through pedigree selection to develop improved versions of PRR78 with blast resistance. Background analysis revealed the recurrent parent genome recovery up to 89.01% and 87.88% in Pusa1602 and Pusa1603 lines, respectively. The hybrids produced by crossing Pusa6A with improved lines of PRR78, were on par with original Pusa RH10 in terms of yield, grain and cooking quality traits with an added advantage of blast resistance. © 2011 Elsevier B.V.

In the present investigation, twenty two elite breeding lines of black seeded soybean [Glycine max (L.) Merrill] were evaluated for 14 agro morphological traits during Kharif 2012 season. Among qualitative traits, presence of multifoliate leaf type was observed only in lines having moderate to high hundred seed weight and presence of anthocyanin pigment on hypocotyl was found related to violet flower colour in black seeded soybean lines. Among quantitative traits, grain yield per plant showed highly significant positive phenotypic and genotypic correlation with traits viz., dry matter weight per plant (0.95& 1.0) followed by 100 seed weight (0.75 & 0.87) and number of pods per plant (0.52 & 0.50). Path coefficient analysis also confirmed that traits viz., dry matter weight per plant and 100 seeds weight along with days to maturity can be considered as the key traits that can play a crucial role in the genetic improvement of black seeded soybean (bhat) genotypes for Uttarakhand hills. © 2016, Agricultural Research Communication Centre.

A field experiment was conducted for three years during rainy (kharif) season of 2006-2008 at Almora, Uttarakhand to study the effect of different weed control methods on weed infestation, energy use efficiency, pro-ductivity and profitability of direct seeded rice (Oryza sativa L.) under rainfed conditions. On an average, a weed population of 627/m2 was recorded in the weedy check plots. The grain yield decreased by 78.5-94.8% due to sea-son-long weed-crop competition as compared with hand weeding (20 and 40 DAS). The highest weed-control effi-ciency and loweet nutrient uptake by weeds was recorded with butachlor + hand weeding (40 DAS) closely fol-lowed by hand weeding twice (20 and 40 DAS). Both these treatments recorded higher grain yield (2.21-2.36 t/ha) compared to other treatments. Butachlor + weeding with wheel-hoe (40 DAS) was the next best treatment. This treatment required less energy input compared with all other weed control treatments. Butachlor + hand weeding and butachlor + wheel-hoe registered the highest energy use efficiency (10.23 and 9.75, respectively) and net re-turns (11, 868 and 11, 299/ha, respectively) compared with other treatments. The benefit: cost ratio was the high-est (1.90) with butachlor + weeding with wheel-hoe closely followed by butachlor + hand weeding and butachlor + long-handled khurpi.

Twelve morphological and a biochemical characters were used to develop the identification key for the establishment of distinctness among Indian soybean (Glycine max (L.) Merr.) varieties. Of the 89 soybean varieties studied, 60 varieties were found to be distinct on the basis of 12 essential characters. Remaining 29 varieties can be classified into 10 groups. These groups were distinct from each other but the varieties within group exhibited similar characters. Characters, viz flower colour, presence and absence of pod hair, colour of hair, and colour of testa were found reliable and reproducible across the zones. The study shall be helpful in identifying most similar reference variety for comparing it with candidate variety. For seeking protection under Protection of Plant Varieties and Farmers Rights Act, the study shall guide the breeder, what essential characters should be incorporated in the new soybean variety to make it distinct from others.
