Abstract
A three reasons yield trial (A106 x A111 x A113), a big-yielding-approved double cross used as check, outyielded the double crosses of College Yellow parentage, although the differences in yield were not significant in several cases. One of the double crosses tested yielded significantly better than College Yellow in the 1956 wet season and in the 1956-57 dry season. Three others outyielded College Yellow Flint in the dry-season test. These four double crosses among College Yellow Flint inbred lines, however, did not yield significantly better than their parent in the 1957 wet season.
Five of the experimental double crosses yielded as high as (A103 x A107)(A111 x A113), and one yielded significantly better than (A102 x A107) (A111 x A113) in the 1956 wet-season test.
The best double crosses namely (A102 x A103) (A104 x A106), (A107 x A109) (A103 x A106), (A106 x A107) (A105 x A106), and (A102 x A106) (A107 x A109) of College Yellow percentage may be recommend for inclusion in general yield trials.
