Evaluation of yield parameters and biochemical characterization of drought tolerant and susceptible chickpea genotypes

Abstract

Thirteen drought tolerant and susceptible chickpea (Cicer arietinum L.) genotypes viz., K850, KWR108, RSG 888, BG 256, BG 362, JG 315, JG 11, SAKI 9516, GCP 105, Pusa 372, Pant G 186, NDG 54 and DCP 92-3 grown on Student’s Instructional Farm of Narendra Deva University of agriculture and technology, Kumarganj, Faizabad and were analyzed for their biochemical composition and yield attributes. The present study was conducted to evaluate the effect of drought stress on number of branches per plant, number of pods per plant, 100 seed weight and sugar composition of chickpea genotypes contributing to their adaptability to drought stress. Number of branches per plant was recorded maximum in genotypes GCP 105 and Pant G 186 in 2013-14 and in the 2014-15 GCP 105 recorded maximum number of branches per plant. Genotype K850 resulted maximum number of pods per plant in both of the year. In case of 100 seed weight genotype RSG 888 gave maximum value in experimental years. Sugar composition i.e. total sugar, reducing sugar and non reducing sugar of tolerant genotype (RSG 888) is highest in comparison to susceptible genotype (Pusa 372).
