优势棉花组合F2代农艺性状变异及其利用价值评估 总被引:1,自引:0,他引:1
The agronomic property of elite cotton hybrid F2 was studied and the results showed that each investigated trait showed consecutive normal dislribution except micronaire,so they were typically quantitative characters controlled by micro-effect polygene. Heterosis analysis indicated that the inbreeding depression of F2 generation Was significant,and the heterosis Was less than F1 in yield and its component traits, but the yield of F2 generation was prior to the control.Heterosis of most fiber property was very low,some of which were negatively significant. The entire variations indicated that the segregation of fiber property trait was objective and abundantin F2 population. 相似文献
