Abstract

Grain yield and other agronomic characters of two groups of foreign corn entries consisting of fourteen foreign hybrids and two open-pollinated varieties were evaluated in UPLB Central Experiment Station in two separate trials during the 1985 - 1986 dry season.

Significant differences among yellow corn entries were observed for all characters except in reaction to mildew disease. Most of the foreign entries generally taller and late maturing compared to the check variety IPB Var. 1. The local check out yielded three hybrids and did not differ significantly from four other entries. Tzi 30 x Tzi 20 gave the highest grain yield among entries.

No significant differences among white corns entries were found except for days to silking, plant height, downy mildew resistance and grain yield. P5124001, a check local hybrid, was similar to foreign entries in plant height and earlier in silk emergence. Downy mildew reaction showed one entry as susceptible while the rest were moderately resistant. Tzi 3 x Tzi 15 was the highest yielder among entries.

Results of this study showed that some entries can be advanced to a more extensive testing for adaptability and stability in performance in several locations. Tzi 30 x Tzi 20 and Tzi 3 x Tzi 15 appeared to be the most promising entries while a few others including a white open pollinated variety may prove useful in the improvement of locally developed corn varieties.
