| dc.description.abstract | ABSTRACT The present research investigation entitled “Physiological evaluation of drought tolerant chickpea genotype suitable for Madhya Pradesh” was conducted during Rabi season 2012-2013 at Research Farm, AICRP on chickpea, Department of Plant Breeding and Genetics, JNKVV, Jabalpur (M.P.). The research experiment was laid out in a Randomized Block Design with three replication and treatment comprised of 32 Chickpea genotypes evaluated under drought conditions. The various genotypes showed marked variability among themselves in relation to their phenological developments, ability of drought tolerance, biochemical estimations, physiological determinants and morphological yield attributing parameters and seed yield under drought conditions. Under drought condition the genotypes flowered earlier than under drought situation similarly other phenological developments also achieved earlier. D3 and D4 required lower time for attainment of reproductive stages as compared to other genotypes under drought condition. Maximum LAI accumulation was obtained up to 30-60 DAS under drought situation D29, D31. Chlorophyll content 30 ,60 ,80, 100 DAS Maximum D1,D26,D30,D31 net photosynthesis significantly reduced under drought condition D14, D2 and D28, transpiration rate reduced in D8, D2, D14, stomatal conductance reduced in D8, D2, D28. Water use efficiency (WUE) significantly reduced under drought condition D25, D23 and D9. Instantaneous water use efficiency (PN/E) significantly reduced under drought condition D24, D21 and D4. The RWC among various genotypes also reduced under drought conditions. D13, D23 and D4 maintained highest RWC at 80 DAS under drought the situations. D23, D8 and D29 maintained highest RWC at 100 DAS under drought the situations. Proline is maximum at D7, D4 and D20 under drought condition. The improvement in structural yield attributing parameters caused a significant impact on maximum realization of yield potential D13, D19 and D21. Maximum grain yield per plot under drought condition is D13, D21 and D16. Maximum biological yield per plot is D21, D13, D12 under drought condition. 100 seed weight is highest at D17, D23, and D22 under drought condition. Harvest index highest at D26, D14, and D10 under drought condition. No. of pod is maximum at D20, D8 and D4. It may be conducted that drought had an additive influence on all phenological developments, physiological, biochemical and morphological yield attributing parameters. D13, D21 and D19 were promising for seed yield and its attributes under drought conditions. The RWC is the good to indicate susceptibility or tolerance capacity of genotypes to drought.. | en_US |
