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
Key words : Durum wheat, combining ability, heterosis, Line x Tester
