| dc.description.abstract | Cluster bean [Cyamopsis tetragonoloba (L.) Taub] is an important under exploited leguminous vegetable crop adapted to arid drought conditions. Even though the crop is drought tolerant in nature, the yield will decrease under severe moisture stress condition hence the study has been conducted to identify the better advanced breeding lines which will suit to water deficit conditions. Nineteen advanced breeding lines including the check variety Pusa Navabahar were raised in pots and screened for relative water content (RWC), which is the most appropriate estimate of plant water status in terms of physiological consequence of cellular water deficit 35 DAS under drought, 7 lines including check were selected for further water stress studies. Stress was imposed by withholding water after 35 DAS except for well watered plants. Physiological parameters such as RWC, SPAD chlorophyll meter, total leaf area, specific leaf area, root traits, leaf area ratio and total dry matter were recorded. Advanced breeding lines like COHBCB 15S2, COHBCB 30S1, COHBCB TL-2 which performed better under water stress condition. Further for evaluating genetic diversity, 22 microsatellite markers were used among 19 lines. A dendrogram was constructed based on unweighed pair group method of arithmetic means (UPGMA) using data derived from 22 SSRs grouped the 19 cluster bean advanced breeding lines into two main clusters with 0.62 similarity. The range of dissimilarity among the cluster bean advanced breeding lines varied from 0.62 to 1.00. | en_US |
