| Summary: | a 2-year data from a 4 × 4 diallel cross was analyzed for flowering behavior and its influencing factors. The results indicated that the cotton set flowers with a spiral model, from below to up, and inside to outside. Environments had rather great effects on average intervals, where the average transverse flowering interval was 5.7 days and the lengthways interval was 2.3 days. Furthermore, different types of genotypes had different flowering behavior. Environment conditions had impacts mostly on early season materials, then the later season ones, and lest on full-season ones. Compared to parents, F<sub>1</sub> was tardier to the environments, and the changing range of flowering interval was smaller. |
