Genotype Difference in Wheat Anther Culture Response and Analysis of Parents Selection
Genotype Difference in Wheat Anther Culture Response and Analysis of Parents Selection
One hundred and four varieties or genotypes of wheat were used to evaluate the effects of genotypes on Anther Culture Response(ACR).The results showed that the callus induction rate of F1 hybrid generation were 13.28%,higher than 6.02% of the F3 generation;the Green plant production rate of F1 were 2.88%,F3 were 1.10%,F1 were 2.6 times of F3. In the same culture conditions, different genotypes vary significantly on the anther culture ability, the Callus induction rate from 0 to 111.43%, Green plant production rate from 0 to 49.29%; Correlation analysis showed that the Callus induction rate, green plant regeneration rate and green plant yield were positively correlated. According to the results of ACR, selected some varieties or genotypes with high-culture ability, high-yield and high-quality genes such as Ningchun 4 variety,in order to provide the basis for hybrid combinations, and to improve the efficiency of anther culture breeding.
