Abstract: The analysis of combining abitity of eight yield characters from 24 pea F₁ hybrids in 4×6 incomplete diallel design experiment was conducted. The results indicated that the differences of Gca of 8 characters were significant at 0.05 or 0.01 level, and the Sca of grain weight per plant was dependent on the harmony between that of number of grain Fer plant and 100-grain weight. Additive gene effects and nonadditive gene effects were important in eight characters, but the plant height was mainly controlled by additivc gene effects, nonadditive gene effects played a more important role than additive gene effect did in other characters.

Key words: PEA, COMBINING ABILITY, YIELD CHARACTERS
