Abstract:

This study aimed to find the gene action, GCA and SCA effects for yield, its components and micronutrients and their association with each other. For this, thirty six crosses (hybrids), nine parents and two checks ICTP 8203 Fe and ICMB 98222 (totalling 47 genotypes) were evaluated during Kharif 2014 at three locations viz., IARI, New Delhi (zone A), IARI Regional Centre, Dharwad (zone B) and National Bureau of Plant Genetic Resources, Regional Station, Jodhpur (zone A1). These locations represented all pearl millet growing zones. Pooled analysis of variance revealed significant differences among genotypes for all the traits studied. Analysis of variance for combining ability exhibited significant differences among parental lines and hybrids for all the traits. The mean squares of GCA and SCA were highly significant for all the traits indicating that both GCA and SCA played an important role in the inheritance of these traits. Thus, the present study highlighted gene action and association among yield and its contributing traits as well as grain micronutrients. Two (ICMR 07999 x IPC 1518 and ICMR 07999 x PPMI 701) of the four hybrids that showed high significant SCA effects for seven traits were also found adaptable over test environments for one or more traits.
