Determination of Selection Criterion for Maximization of Seed Yield in Chickpea (Cicer arietinum L.) under Rainfed and Irrigated Conditions (Research Note)

الملخص


A field experiment was conducted during winter 2001-2002 to construct suitable selection indices for obtaining high genetic gain for seed yield of chickpea for rainfed and irrigated conditions, separately. Selection indices clearly revealed that the number of effective pods per plant, seed yield and early flowering seem to be the most important traits for rainfed condition. Whereas the number of effective pods per plant, seed yield and days to maturity might be more rewarding for obtaining high relative efficiency under irrigated condition. Similar selection indices would be useful under rainfed and irrigated conditions. Early flowering provides longer span of reproductive phase under rainfed condition, while longer maturity period might be more responsive under irrigated conditions. Therefore, besides the high number of pods and seed yield, these component characters could also be considered while exercising selection under rainfed and irrigated conditions.
