Abstract
In order to enrich the cotton varieties and promote the sustainable development of the cotton industry in Guazhou County,excellent new cotton varieties suitable for planting in the cotton area of Guazhou County were selected.Using 7 new cotton varieties collected and introduced as experimental materials,the growth characteristics and yield performance of new cotton varieties were observed,and the main agronomic traits and disease resistance were compared,and the new cotton varieties suitable for planting in Guazhou County were selected.The results showed that Longmian 16 had large boll,strong bolling and outstanding yield.The average yields of seed cotton and lint cotton increased by 44.76%and 39.99%,respectively,compared with the control variety Jiumian 10.The high yield and early maturity of Zhongmian 113 were prominent,and the average yields of seed cotton and lint cotton increased 21.82%and 16.98%,respectively,compared with the control variety Jiumian 10.Zhuangjiahan 902 had high and stable yield with prominent early maturity,and the average yields of seed cotton and lint increased by 17.56%and 18.99%compared with the control variety Jiumian 10,respectively.The number of boll-setting per plant of Jiumian 23 was 8.7,with strong boll-setting,moderate growth period and good disease resistance,the average yields of seed cotton and lint increased by 15.64%and 19.89%,respectively,compared with that of control variety Jiumian 10.The above four varieties showed outstanding comprehensive traits and were suitable for planting in the same ecological area as of Guazhou County.关键词
