Breeding Report on the New Cotton Variety Longmian 16
摘要
Abstract
To breed an early-maturing,high-quality,and disease-resistant cotton variety suitable for mechanical harvesting and to address the incompatibility among early maturity,high quality,and high yield in cotton production in the Hexi Corridor cotton-growing region of Gansu,the Crop Research Institute of the Gansu Academy of Agricultural Sciences developed the new variety Longmian 16 by using FU(code name)as the female parent and Longmian 3 as the male parent through hybridization and backcross combined with marker-assisted selection.In the 2021 to 2022 Gansu provincial cotton regional experiment,the 2-year average lint-seed cotton yield of Longmian 16 was 5 647.2 kg/ha,3.5%higher than the control variety Jiumian 10,the average lint yield reached 2 274.0 kg/ha,6.8%higher than the control.In the 2023 provincial production experiment,the average lint-seed cotton yield was 5 180.1 kg/ha,4.4%higher than the control,and the average lint yield was 2 121.9 kg/ha,7.8%higher than the control.This variety is early-maturing,with a growth period of less than 120 days(≥10℃accumulated temperature of about 3 600℃).Plants are cylindrical,with moderate height and compact architecture.It has good boll-setting performance,with an average of 7.8 bolls per plant,a single boll weight of 5.7 g,and a lint percentage of 40.1%.Fiber quality is excellent,with a length of 31.3 mm,a strength of 32.9 cN/tex,a micronaire value of 4.4,and a uniformity index of 86.6%,meeting the premium cotton standard.It has strong disease resistance,showing high resistance to Fusarium wilt and resistance to Verticillium wilt.It is suitable for promotion in Dunhuang,Guazhou,and similar ecological areas in the Hexi Corridor cotton-growing region of Gansu,with broad application prospects.关键词
