Sucrose metabolism in various source and sink organs of developing sugarcane (Saccharum officinarum L.) plant is accompanied with continuous synthesis and cleavage. In this regard, the involvement of four major enzymes viz. sucrose synthase (SS), sucrose phosphate synthase (SPS), soluble acid (SAI) and neutral invertases (NI) is considered crucial. In this study, we have analysed in vivo enzymatic activity of 12th month old field grown radiation-induced sugarcane mutants identified for sucrose accumulation. The mutants showed significant differences in the spatial enzymatic regulation in leaves, immature and mature internodes; SPS and SS activities were found highest in high sucrose accumulating mutants (AKTS-02 and AKTS-20) along with lower levels of SAI activity. Overall positive correlation of SPS, SS and negative correlation of SAI, NI activities with sucrose content of the respective tissue types was observed. The SPS activity was found strongly associated with sucrose content in leaves (r2 = 0.558) and internodes (r2 = 0.514), whereas, the SAI activity was found significant in leaves (r2 = 0.379) and weakly associated in internodal tissues (r2 = 0.248). However, the associations were found to be non-significant for SS and NI activities in both leaves and internodes. Despite this, the differences in the SPS and SAI activities (SPS-SAI) in leaves (r2 = 0.828) and internodal tissues (r2 = 0.619) had shown greater influence on net sucrose synthesis and accumulation. To summarize, our results suggest differential sugar metabolism in the induced mutants and that such contrasting mutant germplasm with a relatively uniform genetic makeup can be useful in molecular studies on sucrose accumulation. © 2016 Elsevier Masson SAS.

Mass multiplication of Zygogrmma bicolorta P. was initiated at Biocontrol Laboratory, Anand Niketan College of Agriculture, Anandwan, Warora, District Chandrapur, Maharashtra, in June 2011 for the control of Parthenium hysterophorous L. weed. Culture of Zygogramma was brought from uncultivated land of Umarkhed District Yavatmal (M.S.) where these beetles were well established. Zygogramma culture was released in the Experimental plot, field adjoining to the biological control laboratory, field of A. N. College of Agriculture Warora and also in Anandwan premises. Mass multiplication of Zygogrmma also carried out in plastic containers in the Laboratory. Defoliation of Parthenium by both the grubs and adult beetles was found to cause reduction in flower production and also stunting of the growth of weed. The beetles completely defoliated the Parthenium plants and the plants were completely dried. On the experimental plots it was observed that after complete defoliation and eradication of Parthenium dispersal of Zygogramma beetles occurred and also some beetles recorded during feeding on Gokhru (cocklebur) Xanthium strumarium L. weed which belongs to the the same family Asteraceae as that of Parthenium. From this it was concluded that after complete defoliation or eradication of Parthenium weed Zygogramma may feed on the Xanthium for survival or existence and in future Xanthium may become as a new host of Zygogramma in the absence of Parthenium.

Blister beetle, Mylabris phalerata is a serious pest of short-duration crops like greengram and blackgram. The adult beetles feed gregariously and devours buds and flowers translating in heavy yield reduction. The data on blister beetles density and corresponding loss in pod bearing and grain yield in mungbean varied inversely. The blister beetle density of 1, 2, 3, 4 and 5 beetles per meter row length (mrl) registered decreasing yield trend of 1240,1120, 950, 750 and 573 kg/ha with corresponding avoidable losses of 9.7,18.4,45.4,58.3 and 68.4 per cent, respectively. The lowest yield was recorded at 8 beetles per mrl (136.7 kg/ha) with avoidable loss of 90.0 per cent, indicating immense damage potential of blister beetles. The economic threshold level of 0.4 blister beetles per mrl is reported for the first time on greengram. The linear regression equation of y = 11.75-1.208 × and y=1398.0-158.6 × was set for prediction of loss in pod bearing and yield loss, respectively. The estimated ETL predicted yield loss of 4.7 per cent and loss in pod bearing of 4.2 percent which validated the established ETL.

Generation mean analysis study in chickpea was undertaken to estimate the gene action operating in the inheritance of yield and its components. Six basic generations viz., P1, P2, F1, F2, BC1 and BC2 of two crosses, namely ICCV 2 × PKV Harita and ICCV 2 × HC 5 were studied. Joint scaling test was applied to test the adequacy of additive-dominance model for the traits under investigation. Significant χ2 values indicated the presence of higher order interactions except for days to maturity in ICCV 2 × PKV Harita cross and number of primary branches per plant and number of pods per plant in ICCV 2 × HC 5 cross. The dominance component was higher in magnitude than additive component for all the characters studied along with duplicate type of epistasis in most of the cases. Both, additive, and non-additive gene action contribute significantly in the inheritance of various quantitative characters in chickpea. Moderate to high broad sense heritability and low narrow sense heritability was noticed for most of the traits studied. Further low to moderate genetic advance coupled with low genetic advance as per cent of mean was detected for most of the characters studied indicating the great influence of environmental effects. Hence, the biparental approach or inter-mating of desired segregants in early generations followed by delayed selection would be ineffective.

Biochemical analysis was carried out for 10 isolates of Pseudomonas fluorescens. All isolates were found positive for siderophore and indole acetic acid production (except Pf IX) and phosphate solubilisation (except Pf VII). Biochemically efficient strains (Pf I, Pf IV, Pf VII and Pf IX) were selected for management of root rot, collar rot and damping off caused by Phytophthora parasitica, Pythium sp. and Fusarium solani. The activity of defence-related enzymes like esterase, peroxidase and polyphenol oxidase was also detected by polyacrylamide gel electrophoresis (PAGE). Consistent appearance of esterase isozyme bands was visualised, in the range of 0.193-0.349. The highest Rm value 0.349 was observed on Pf IV. Whereas, for peroxidase, Rm value ranged between 0.302 and 0.373 and for polyphenol oxidase, it was in the range of 0.211-0.800. P. fluorescens Pf IV was found significantly effective to arrest the per cent mycelial growth of P. parasitica (55.20%), Pythium sp. (65.33%) and F. solani (64.67%). Among bioagents, seed treatment and soil drenching with Pf IV at 15 and 30 days after sowing were found effective to reduce per cent disease incidence (30.55%) at 120 days after emergence. Seed treatment with copper oxychloride at 3g/kg seed and metalaxyl at 2 g/kg seed were also found effective. © 2011 Taylor & Francis.

This paper analyses the various factors that had influenced the adoption of adaptation measures by the farmers in response to climate change and variability in distress prone districts of Vidarbha region in Maharashtra. The data used in the analysis were obtained through face to face interviews of 300 farmers in 10 villages scattered over 5 tahsils of 2 highly farmers' suicide prone districts in 2012. Influence of 27 independent variables on the adoption of adaptation measures (dependent variable) was studied. The results of regression analysis indicated that the t- value for partial b of adaptive capacity (3.098) was significant. All the 27 variables fitted in a regression equation accounted for 75.30% (R2 = 0.753) variation in adoption of adaptation measures. Regression analysis further revealed that annual income, perception towards climate change, extension contact, farming experience and social participation were the major factors influencing adoption of adaptation measures. Use of different adaptation measures significantly increase for farmers under study area with more access to these factors. Designing policies that aims to improve these factors for small holder farming systems have great potential to improve farmers' adaptation to changes in climate and variability in the region. © 2016, Indian Council of Agricultural Research.
