| Popis: | A field experiment was conducted to evaluate the performance of hybrid (BJ 104, MBH 110, CM 46 and GHB 27) and composites (PSB 3, PSB 8, WCC 75 and Local) of pearl-millet on the soils (pH 7.1, Organic carbon 0.5 %, P2O5 9.6 kg/ha, K2O 80 kg/ha, soil depth 65 cm and profile moisture 8.6 cm) of Indian Grassland and Fodder Research Institute, Jhansi under extreme drought condition (340 mm total precipitation during the crop season). It was observed that hybrids, by and large, gave higher production than composites and local variety even failed to bloom. Further the highest yield from hybrid MBH 110 was due to its drought escaping character (earliness), drought enduring capacity (CSI-12), efficient translocation and better sink strength. BJ 104 and CM 46, though were also drought escaping and possessed capacity to endure drought but inferior to MBH 110 in sink strength which was ultimately reflected in production. An appraisal of the various agro-physiological traits revealed that earliness, high harvest index, low CSI value (chlorophyll stability index) and high sink strength were directly correlated with productivity of cultivars under drought condition which could be used as a guide lines for breeding drought resistant cultivars of pearl millet. |
