Abstract
High combining inbred lines, some of which were previously extracted from College Yellow Flint of Cuban Yellow flint varieties and others obtained from the United States of Columbia, South America were combined into 4-line, 6-lines and 8-lin synthetics.
Not one of the nine synthetics outyielded significantly the College Yellow Flint variety although the mean yields of most synthetics were much higher. The lack of statistical significance in the 1956-57 dry-season test was probably to the high coefficient of variation (22.26%). However, two synthetic varieties (Syn. 1i and Syn 1h)yielded significantly better than the College Yellow flint variety in the 1957 wet-season performance test. The yields of these two synthetics were as high as that of Phil. Hybrid No. 1d, a double-cross hybrid recommended by the Philippine Seed Board.
There was no significant difference between the yield of the first generation synthetic and those of the second generation synthetic.
