Prediction on F_2 Heterosis of Head Traits in Cauliflower
Yang Jiafu et al (Dept. of Biological and Environmental Sciences, Wenzhou Normal College, Wenzhou, Zhejiang 325027)
Seven parents of cauliflower and 20 F 1s were analyzed in their head traits according to a genetic model of additive-dominance. F 1 heterosis were predicted by using the data of parent and F 2. The results indicated that head traits were mainly controlled by dominance effects and with larger heterosis, some combinations were with larger F 2 heterosis.
