The agronomic property of elite cotton hybrid F2 was studied and the results showed that each investigated trait showed consecutive normal distribution 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 abundant in F2 population. 展开更多
