Evaluation of Superior Durum Wheat (Triticum durum, Desf.) Genotypes Grown in Field Experiment and in vitro

摘要

EVALUATION experiments for thirteen durum wheat genotypes included two local varieties and eleven introduced lines during two successive seasons. The tested genotypes showed highly significant differences in growth characters, yield components in thetwo growing seasons and their combined analysis. Callus induction, callus growth rate and plant regeneration were evaluated for all tested genotypes through tissue culture MSWD-2 line followed by MSWD-9 surpassed the other tested genotypes in number of tillers/plant, main spike weight (g), spikes weight/plant (g), 100-grains weight (g), grains yield/plant (g), grains yield ton/fedden, callus induction, callus growth rate and plant regeneration. However, MSWD-19 genotype is the tallest one, while the NRCWD-32 produced the highest value of main spike length. High genetic advance, as percentage of the mean, was found to be associated with high heritability values in cases of main spike weight, spike weight/plant, 100-grain weight, grains yield/plant and grains yield ton/fed. Superior genotypes are used in breeding programs to save much efforts and costs to breeder.
