Analysis of Combining Ability and Genetic Parameter of Yield Characters of Balsam Pear

GAO Shan~1,LIN Bi-ying~1,ZENG Xiao-lin~1,LIN Zhi-liang~2(~1Fuzhou Institute of Vegetable Crops,Fuzhou 350012,China;~2College of Crop Science,Fujian Agriculture and Forestry University,Fuzhou 350002,China)  
Twenty-four hybrid combinations were got through incomplete diallel cross between 6 female parents and 4 male parents of balsam pear.The combining ability and the genetic ability of yield characters were analyzed.The result showed that there was a very significant difference in the specific combining ability(SCA) of flesh thickness character,and the general combining ability(GCA) and SCA of the other 8 characters reached very significant level.The anthesis of female flowers,rate of female flowers,fruit length,fruit weight,fruit number per plant,early yield and total yield were controlled by additive genes.The narrow heritability and the broad heritability of female flowering time,rate of female flowers,fruit number per plant,early yield and total yield were all rather high,and these characters should be selected in the early generations.The parents,Number 6,12-C,24-B,Number 8 and Number 99,proved to be perfect parents because of their high general combining ability.
