摘要
Abstract
Seeds of Chinese-fir produced by three kinds of mating design in Dongfeng Forest Farm, Liping county were tested. The quality of seeds originated from various mating crosses differed significantly. Sel-fing was one of the primary causes producing tannic seeds, but it had no significant effect on the production of empty seeds. For most seed traits, general combining ability ( GCA ) , special combining ability ( SCA) and reciprocal effects also differed significantly in various crosses. In the tests of disconnected half-diallel and polycross, GCA is greater than SCA, and more significant for female parents than male. For complete diallel mating design, if selfing crosses were reduced, the result would be similar to partial half-diallel and prolycross tests.关键词
