Abstract
Four rates of sodium chloride solution (0(water), 0.5%, 1.5%, 3.0%, 4.5% and untreated) were treated by spraying to the opened and unopened flower of line 27-3-7 about 1 hour after self pollination. Results show that thebrate 0.5% gave the highest mean seed set of 9.0 seeds/pod or 6.5 seeds/flower (from flowering stage) ,however the seed set from bud pollination were not significantly different, statistically. Three inbred lines which express strong self incompatibility were hand crossed in all possible combinations. The F1hybrid and parents were tested in comparison with the 2 commercial varieties. Only hybrid 142-8x 27 gave the better yield than others. Consequently this hybrid should be futher tested in farmer's field.
