| Abstract: | Objective]The purpose was to study the correlation between main agronomic traits and single plant lint yield in upland cotton with high quality.Method] Twenty-four upland cotton lines with high quality were analyzed for single plant lint yield and 10 agronomic traits in a randomized, complete block at the agriculture experimental station of JXAU, Nanchang, China in 2007. They were divided into three types (high, total of 11 traits of three types were compared. Correlation analysis and stepwise regression analysis of 10 agronomic traits to single plant lint yield were carried out.Result]There existed statistically significant difference in bolls per plant, lint percentage, lint index, fruit node numbers, growth period for three yield types. The high yield type exhibited the highest bolls per plant, lint percentage and lint index, the lowest fruit node numbers and the shortest growth period. Bolls per plant, boll weight and single plant lint yield were significantly and positively correlated. Fruit node numbers and single plant lint yield were significantly and negatively correlated. Bolls per plant, boll weight, and fruiting position number were the most important factors influencing single plant lint yield of upland cotton lines with high quality.Conclusion]The results will have certain significance for the development of upland cotton variety with high quality. |
