Analysis on Heredity Effects of Half-Sib Progeny and Superior Ribes nigrum Family Selection
Annotatsiya
The heredity effects of fruit characters from half-sib progeny were discussed,and the superior families were selected based on analysis of the genetic variation. The results showed that,there are certain differences on the berry characters among the families,and the coefficients of variance of the fruit diameter(2. 75%) were smaller,but its each fruit cluster weight(32. 36%) were larger and its average fruit weight(40.41%) were the largest. Meanwhile its berry character had strong heritability and medium genetic gain,and its genetic diversity was smaller.The heritability of the fruit diameter and the fruit cluster weight were 0. 995 and 0. 811,and the genetic gain were 1. 28% and 9. 67%,respectively. So,taking influencing factors into consideration,RINI07 were determined to be the superior family.
