Abstract:

High heterozygosity on the one hand, and the inability to carry out successful hand pollinations on the other hand, have limited the amount of systematic work which has been done in mango breeding. In studying the inheritance of important horticultural traits we must first analyse the distribution of different traits in seedlings derived from open pollination. We studied correlations between these traits and assessed the contribution of the three female parents to that distribution. Although in general the trait distribution pattern is similar among the three progenies, some differences were noted. We also detected some correlations among various traits which might be useful for future breeding. It was concluded from both a chi-square test and an intraclass correlation coefficient that there is a specific female parent effect on both harvest season and fruit color; a smaller effect was found on fruit taste and size, and no effect of the female parent tree was detected on the distribution of both the juvenile period and fertility. © 1989 Kluwer Academic Publishers.
