Abstract
Abstract A field experiment was conducted to study the varietal variability of productivity in sorghum under rainfed conditions. Six varieties viz., TNS 24, TNS 27, CO 20, CO 19, CO 24 and K3 were utilized in this study. Among these varieties TNS 24, CO 19 and TNS 27 were found to be tolerant to drought situations while K 3, CO 20 and CO 24 were susceptible. The classification was mainly based on the yield data. Highest leaf area was observed in tolerant varieties, The reduction in leaf area at the harvest stage was also minimal (6.8%) in the tolerant varieties. LAD and CGR also showed higher values in the tolerant varieties. The dry matter accumulation was higher in the tolerant varieties. The yield improvement in the tolerant genotypes is mainly due to the increased dry matter accumulation while harvest index is not related to yield in the varieties studied.
