Summary: Present investigation was undertaken to enhance adaptation of chickpea to water limited environments as this crop is grown in dry areas and more than 80 percent cultivated area is rainfed worldwide. This study was planned to investigate the major objectives; to enhance genetically the chickpea adaptation to drought prone areas, to evaluate the relative performance of various crosses under both rainfed and irrigated environments and to identify suitable drought tolerant populations for dry farming system. For this purpose 10 crosses were developed between resistant x susceptible, susce- ptible x susceptible, resistant x adapted and resistant x resistant parents. The relative perfor-mance of seed yield and its componential traits in all the segregating populations of each cross was compared with parental lines and check varieties. It is important to mention that out of 10 crosses only five crosses were found more suitable in producing drought tolerant superior segregating populations, three crosses produces more segregants suited to irrigated environments and two crosses were found undesirable for both the environments because the perfonnance of segregating populations was inferior to all the checks. Thus, out of 10 crosses five crosses were found suitable in producing drought tolerant and high yielding populations. It is possible when well adapted and drought tolerant parents are involved in the hybridization and new recombinations emerge producing new genes pools suited to moisture stress environments. The selection of these single plants which contain such favorable gene pools suited to a particular environment depends on the selection approaches and strategies adopted during generation advancement. Based on these findings it was concluded that genetically it is possible to develop desirable gene pools through genetic manipulations during hybridization suited to a particular environment. From present investigations it is evident that the drought tolerant populations were emerged due to the adoption of such genetic and breeding strategies. Thus, it was suggested that adaptation of chickpea to water limited environments can be enhanced genetically by using appropriate breeding approaches in the development of segregating populations.

Abstract only

Present investigation was undertaken to enhance adaptation of chickpea to water limited environments as this crop is grown in dry areas and more than 80 percent cultivated area is rainfed worldwide. This study was planned to investigate the major objectives; to enhance genetically the chickpea adaptation to drought prone areas, to evaluate the relative performance of various crosses under both rainfed and irrigated environments and to identify suitable drought tolerant populations for dry farming system. For this purpose 10 crosses were developed between resistant x susceptible, susce- ptible x susceptible, resistant x adapted and resistant x resistant parents. The relative perfor-mance of seed yield and its componential traits in all the segregating populations of each cross was compared with parental lines and check varieties. It is important to mention that out of 10 crosses only five crosses were found more suitable in producing drought tolerant superior segregating populations, three crosses produces more segregants suited to irrigated environments and two crosses were found undesirable for both the environments because the perfonnance of segregating populations was inferior to all the checks. Thus, out of 10 crosses five crosses were found suitable in producing drought tolerant and high yielding populations. It is possible when well adapted and drought tolerant parents are involved in the hybridization and new recombinations emerge producing new genes pools suited to moisture stress environments. The selection of these single plants which contain such favorable gene pools suited to a particular environment depends on the selection approaches and strategies adopted during generation advancement. Based on these findings it was concluded that genetically it is possible to develop desirable gene pools through genetic manipulations during hybridization suited to a particular environment. From present investigations it is evident that the drought tolerant populations were emerged due to the adoption of such genetic and breeding strategies. Thus, it was suggested that adaptation of chickpea to water limited environments can be enhanced genetically by using appropriate breeding approaches in the development of segregating populations.
