Abstract

Nine inbred lines developed by the National cooperative Testing Project of the Department of Agronomy were characterized and evaluated for per se performance in a randomized complete block design at Central Experiment Station, University of the Philippines at Los Baños from November 1994 to February 1995.

Highly significant differences among the inbred lines were noted in all traits measured. Distinct differences in characters were likewise observed indicating inherent genotypic characteristics among the inbred lines.

Inbred A13 had the best standibility, the most number of kernels per row, and the heaviest ears. Inbred A457 had good seedling vigor and was the most prolific in producing ears. Inbred A123 was the shortest and had wide ear diameter. Inbred A113 is early in shedding pollen at 50.75 days after planting. Inbred A62 had the longest ears while A15 had the most number of kernel row. Inbred A757 had the lowest moisture content and the earliest to moisture.

Inbred A13 was the highest yielder at 3.74 tons per hectare. The other inbreds with good seed producibility were A15, A757, A62, A121, A113, A968 having yields ranging from 2.72 to 3.70 tons per hectare.

The inbred lines, based on per se performance generally possessed good agronomic characters and are worth further evaluation in hybrid combination.
