An investigation was conducted at organic research farm, Department of Vegetable Science, CCS Haryana Agricultural University, Hisar to study the effect of intercropping and crop geometry in organic production of broccoli (Brassica oleracea var. italica) during winters of 2012-14. Three organic manures (FYM, vermicompost and poultry manure) and two spacings, viz. single row (45×45cm) and paired row (30/60×45cm) were taken in main plot and five intercrops, viz. broccoli (CBH-1), beet leaf (HS-23), coriander (Hisar Bhumit), fenugreek (Hisar Suwarna) and radish (HS-1) including sole crop of broccoli as sub-plot. The trial was replicated thrice. The experimental results revealed that sole crop of broccoli with the application of vermicompost in single row spacing (M2S1C1) recorded minimum days to first and 50% harvesting (56.7), maximum number of leaves (28.4), weight of main head (200.2g), girth of head (15.4cm), number of sprouts/plant (9.8), yield of sprouts/plant (400.9g), yield of sprouts (main head + sprouts)/ plant (601.1g), total yield (296.9 q/ha), plant biomass on fresh (1 661 g) and dry weight basis (149.2 g), of broccoli. While plant height (63.45cm) and yield of intercrops (127.1 q/ha) was recorded maximum with the application of vermicompost in double row spacing (M2S2C5) treatment with radish. Among the intercropped treatments, fenugreek intercropped with broccoli recorded maximum yield (287.7 q/ha) in single row spacing.

Genetic variability and heritability for morphological and phytochemical attributes were studied in Morinda tomentosa. The magnitude of genotypic coefficient of variation was higher for all but number of seeds per fruit, flavonol content in leaf, number of branches per plant, flavonol content in fruit, fruit length, total soluble sugar, plant height, ascorbic acid content in fruit and fruit width indicating lesser role of environment in the expression of the traits. The broad sense heritability was higher for all but fruit width indicating explicit realization of heritable variance and thereby offering abundant chances of improvement in those characters by simple selection. The higher estimates of genetic advance with high heritability for total phenol content in leaf, carotenoid content in leaf and fruit inferred role of additive gene action in the expression of these traits that further corroborated phenotypic selection based on these traits to be more effective. © 2016, IndianJournals.com.

The nutrient management strategies for rational fertilizer application were developed for Coorg mandarin through crop specific and reliable nutrient standards/norms using Diagnosis and Recommendation Integrated System (DRIS) technique. DRIS provided comprehensive leaf nutrient standards for diagnosis of nutrient imbalance for Coorg mandarin. DRIS is a dual ratio concept where the nutrient concentration ratios were considered rather than absolute nutrient concentrations in isolation. The diagnostic norms were essentially developed through a survey conducted in Kodagu region in Karnataka. The data bank of nutrient concentration vs. yield was divided into two sub-groups as low and high yielding based on the yield potential in individual orchards. The individual nutrient concentrations were expressed in as many forms as possible (e.g. N/P, N X P). The variance ratios and coefficient of variation were calculated for all forms of expressions. The nutrient expressions with high variance ratio and low coefficient of variation were chosen as diagnostic norms. Twenty eight nutrient expressions were derived for identification of nutrient imbalance in Coorg mandarin. Among the nutrient expressions selected as diagnostic norms for Coorg mandarin, some expressions such as N/P (6.427), N/K (1.703) and P/Zn (0.0134) were found to have greater physiological rationale in seedling plants. The ratio of N/P (7.17), N/K (1.395) and Zn/P (77.80) and Ca /Mg (5.92) were found important in budded plants. The nutrient imbalance in plants was diagnosed through DRIS indices. DRIS identified zinc and magnesium as the most yield-limiting nutrients.

Morinda tomentosa Heyne (Rubiaceae) an evergreen small tree also known as Aal or Indian Mulberry or Nunaa has broad range of therapeutic and nutritional value and is broadly used for making morindone dye for the dyeing of silk, cotton and wool. This is the first report wherein twenty genotypes of M. tomentosa, an underutilized fruit plant collected from Madhya Pradesh, India were studied for genetic diversity analyses using 131 Start Codon Targeted Markers (SCoT) (gene based) and 97 Random Amplified Polymorphic DNA (RAPD) and 70 Inter Simple Sequence Repeat (ISSR) (neutral) markers. SCoT markers showed the highest level of polymorphism, Shannon’s Information Index and Polymorphism Information Content (70.23 %; 0.31 ± 0.27; 0.189 ± 0.103), while the total number of bands per primer (7.0) was highest for ISSR markers. Nei’s gene diversity (0.20) was found similar for both ISSR and SCoT markers. And geographical clustering was most pronounced with ISSR followed by SCoT and RAPD markers. Cumulative marker data revealed best clustering of genotypes based on their areas of the collection. And individually, our results showed the efficacy of both SCoT and ISSR (co-phenetic correlation values of 0.79 and 0.76 respectively) over RAPD (co-phenetic correlation value of 0.69) markers for genetic diversity and geographical patterning studies of M. tomentosa. Additionally, structure analysis grouped the twenty M. tomentosa genotypes into two sub-populations, this structuring and the identified markers can be utilized for making further strategies for collection and conservation of M. tomentosa from Madhya Pradesh and other states of India as well as for global collections. © 2014, Springer Science+Business Media Dordrecht.

The experiment was conducted during consecutive years of 2005-06 and 2006-07 at Central Horticultural Experiment Station (Central Institute for Arid Horticulture-ICAR), Vejalpur (Godhra), Panchmahal, Gujarat to standardize time of softwood grafting in mahua (Bassia latifolia Roxb.) and khirni (Manilkara hexandra (Roxb.) Dub.) under semi-arid environment of western India. Softwood grafting was carried out at monthly interval commencing from July to June during both the years. Sprouting was found to be the earliest in March (26 days in mahua and 27.4 days in khirni). Maximum time for bud sprouting was taken in the month of September (34.00 days) and November (33.50 days) in mahua and khirni respectively. The highest percentage of graft success was also noted in March, i.e. 70.00 % in mahua and 76.66 % in khirni, it was closely followed by July, August and June. Least percentage of success was noted in the month of September and November in mahua and khirni respectively. Length of sprout was also recorded highest in March after 180 days after grafting in both the crops (28 cm in mahua and 22 cm in khirni). Similar trend was recorded in respect of number and diameter of sprouts. Softwood grafted plants of mahua had higher number of leaves than khirni grafts, whereas it was found to be highest in the month of March in both the crops. Irrespective of scion and rootstock, the maximum accumulation of nitrogen and carbohydrate content was recorded in March, while it was found in lower concentration during December, January and February. Soft wood grafting in mahua may be followed during March, April and July, while March, July and August may be the appropriate time for grafting of khirni under semi-arid environment of western India.

Jelly seed (JS) in ‘Amrapali’ mango (Mangifera indica L.) is a physiological disorder, the cause of which has long remained obscure. The disorder is distinguished by the appearance of jelly-like tissue in the pulp adjoining the stone, although the fruit show no external symptoms. The objective of this study was to determine the causative factor inducing the JS disorder in ‘Amrapali’ mango. Studies showed, for the first time, that JS in ‘Amrapali’ mango arose at the start of germination-associated events in the seed of developing fruit. The trigger for premature seed germination originated from reduced synthesis of very-long-chain fatty acids (VLCFAs) in the seed of developing fruit. This then promoted the production of cytokinins, leading to the onset of premature germination-associated events in the seed. Consequently, a large increase in the activities of pectinolytic enzymes in JS pulp occurred that led to the rapid degradation of pectin and excessive softening of the pulp, to the consistency of jelly. The application of plant growth regulators to developing fruit showed that gibberellic acid (GA3) increased the incidence of JS, while paclobutrazol reduced the incidence of JS, confirming that the onset of early germination during fruit maturation and ripening played a primary role in the incidence of the JS disorder. © 2016 The Journal of Horticultural Science & Biotechnology Trust.


Among the various pests that attack pomegranate, anar butterfly, Deudorix (=Virachola) isocrates Fab., has assumed a major status limiting the cultivation of this crop in and around Panchmahal district of Gujarat, India. An attempt was therefore made to study varietal reaction, extent of damage and management of borer in commercially grown cultivars of pomegranate. In all, there were five cultivars viz., 'Ganesh', 'Mridula', 'Jyoti', 'Ruby' and 'Jalore seedless' which were replicated four times. There were four plants in each replication. The crop chosen for the experiment was the late Hasta and early Ambe bahar crop. In order to retain the crop, need based irrigation was given at regular interval. Bagging was resorted for management of borer. Observations on varietal reaction to borer revealed that all cultivars were found to be equally susceptible to borer attack. The incidence ranged between 35.0% in 'Jalore seedless' to 42.0% in 'Ganesh'. Gradually, it increased from 50.0 to 60.0% in the second week of March. The situation was however further deteriorated and almost 80-90% fruits were found to be damaged by borer in unprotected plot. The experiment on bagging of fruits showed significant reduction on percentage damaged fruit and the extent of damage was observed to be below 10.0% in almost all cultivars as against 90.0% in open fruits.

The experiment was carried out at the CHES Vejalpur farm with pomegranate 'Ganesh' grown under rainfed conditions. The climate of the area is semiarid with mean rainfall of 750 mm, during the experimental period. The mean maximum temperature of the area was 44°C and mean minimum was 10°C. The depth of the soil ranged from 0.75 to 1 m, with a pH range of 7.5 to 8.1. The soil of the area is saline in nature. The crop was raised at 5×5 m spacing (400 plants/ha). Root distribution acts as a guide for application of fertilizers as well as irrigation. Root distribution varies according to the type of soil, method of propagation. No such work was carried out in India on pomegranate. Therefore studies were initiated to study root distribution pattern of air layered six-year-old pomegranate 'Ganesh'. The root distribution pattern in air layers of pomegranate 'Ganesh' under semi-arid rainfed conditions revealed that the root system is shallow in nature as below 60 cm soil depth not much root activity was recorded. Maximum root activity on fresh and dry wt. basis was observed in 0-30 cm radial distance from tree trunk (54.17%), which was 31.12% in 30-60 cm radial distance and 2.12% in 60-90 cm radial distance. However, soil depth wise it was maximum at 30-60 cm and 42.69% at 0-30 cm depth. It was least (3.74%) at 60-90 cm depth.

A fertile female backcross progeny was produced from an inter-specific hybrid [teasel gourd (Momordica subangulata Blume subsp. renigera (G. Don) WJJ de Wilde)×spine gourd (Momordica dioica Roxb)] by backcrossing the F1 with the female parent. Agro morphological and biochemical traits of the first generation backcross (F1 ♀ BC) confirmed interchanges of genetic material. The F1 ♀ BC bear more resemblance to maternal parent than the paternal parent and exhibited substantial heterosis for number of flowers and yield per plant. In F1 ♀ BC, fruit set was significantly higher when pollinated with teasel gourd (84%) while the fruit set was very low upon sibbing (36%) and pollination with spine gourd (64%). The fruits of F1 ♀ BC had little variation for shape from teasel gourd when pollinated with teasel gourd pollen, while fruits obtained from sibbing and dusting of spine gourd pollen were deformed and smaller in size. The proximate and phytochemical analysis revealed that the F1 ♀ BC was intermediate between the original parents in its biochemical traits and antioxidant activity while mineral content was found to be higher or similar to its parents. The present study shows the potential for improving Momordica species through inter-specific hybridization followed by restoration of fertility by backcrossing. © 2014 Elsevier B.V.
