Abstract

Great difficulty in pod setting and development was experience when Vigna sinensis (bushy) was crossed with Vigna sinensis var. susquipedalis (viny) plants. When successfully crossed, however, a fair amount of seeds per pod developed was obtained.

Although the F1 hybrids were intermediate between the parents in habit of growth, they were classifiable as bushy types. When selfed the F1s segregated in the second generation in monohybrid ratios of 3 bushy to 1 viny plant.

Pod maturity in the F1s was as early as the early parents. In the F2s, some plants were as early as the early parents. But some were even than the late parents.

Pod length in the F1s and F2s was intermediate between the two parent extremes. However, inspite of the considerable increase in pod length in the F1 and F2 plants, no increase of seeds per pod was obtained.
