| Abstract: | A four-parent complete dialleld mating-set of three Triticum aestivum L. cultivars ‘Edwall’, ‘Chris’ and ‘Spillman’, and an alloplasmic line of ‘Selkirk’ in Aegilops variabilis Eig. cytoplasm was used. Genetic components among total variation for callus induction, green plant percentage and green plant yield werr 92%, 80% and 77%, respectively, but lower (36%) for plant regeneration. General combining ability (GCA) variance components and narrow-sense heritabilities estimated for callus induction, green plant pereentnge and green plant yield were 74%, 66%, and 53%, and 0.68, 0.54 and 0.43. respectively. Specific combining ability (SCA) variancw was calculated as 85%) of total genctie variation for plant regeneration. Significant reciprocal effects for callus induction. green plant percentage and green plant yield were observed. |
