HETEROSIS AND HETROBELTIOSIS PERFORMANCE OF MORPHOLOGICAL TRAITS IN BREAD WHEAT CROSSES UNDER DROUGHT STRESS CONDITIONS
Said Salman*, Shah Jehan Khan* and Javed Khan**
The study was designed to observe the heterotic and heterobeltiotic effects in F s of four different crosses having four drought 1 tolerant cultivars and four susceptible lines as parents. The experiment was conducted at the Faculty of Agriculture, Gomal University, Dera Ismail Khan, Pakistan during 2012-13. The performance of crosses and their parents were evaluated with three replications. These crosses were -1 evaluated for plant height, number of tillers plant , days to 50% heading, -1 -1 spike length, number of spikelets spike , number of grains spike and 1000-grain weight. Maximum heterosis and heterobeltiosis interactions were noted in Pari-73 x Hashim-08 for 1000-grain weight (29% and 22%), grains per spike (19% and 11%) and spike length (33% and 22%). Promising results were obtained with respect to shorter plant height, maximum spike -1 length, more spikelets and grains spike and achieved all results important for drought resistant cultivars.
