Combining ability and heterosis for yield and grain quality in durum wheat (Triticum turgidum var. durum)

Abstract

Forty hybrids involving ten lines and four testers were evaluated for combining ability and heterosis. Among the parents HD 4672, HD 4694, HI 8498, HD 4676 and PDW 233 were found best for yield as well as quality traits based on the mean and gca effects. Considering the mean performance, sca effects and heterosis, five hybrids viz., HI 8596 x Trinakaria, HD 4692 x WH 896, HD 4694 x PDW233, HI 8653 x PDW 233 and HD 4695 x Trinakaria were superior for grain yield, five hybrids viz., HI 8381 x Trinakaria, HD 4694 x WH 896, HD 4694 x HD 4676, HI 8651 x HD 4676 and HI 8653 x HD 4676 for quality traits and two hybrids HD 4694 x HD 4676 and HI 8498 x HD 4676 were found best for yield and quality traits both. Hence, these hybrids were suitable for generating good segregants for yield along with quality traits
