从江西省棉花品种区试看近几年育种趋势变化

The Breeding Trend Changes in Recent Years from Regional Test of Cotton Variety in Jiangxi Province

采用2006-2013年江西省棉花品种区域试验的资料,从主要农艺、产量性状和纤维品质进行分类汇总与分析。结果表明：参试品种的株型偏高大、生育期偏中早熟;单株铃数和铃重、籽指和衣分没有协调统一,产量选育的突破遇到了瓶颈;纤维长度、马克隆值、比强度均得到了提高,重视了优质目标性状的选育。建议在今后杂交棉品种的选育中,要注重对抗非生物逆境能力品种的培育,加强单株铃数和铃重、籽指和衣分的协调统一,突破产量瓶颈;进一步提高纤维品质性状的培育,以选育出高产优质兼顾的杂交棉新品种,服务于长江流域棉区。

The paper used the data of regional test of cotton varieties in Jiangxi province from 2006 to2013, statistical analysis summary classification from the main agronomic characters, yield characters and fiber quality. The results showed that： the higher plant type, growing stages of puberty; boll number per plant and boll weight, seed index and lint percentage had no harmonization, yield breeding breakthrough existed bottlenecks; fiber length and micronaire value and specific strength were improved, paying attention to the selection of high quality target shape. It suggested that in the future breeding hybrid cotton varieties, we should pay attention to the fight against abiotic stress ability of species, strengthening coordination and unification of boll-number per plant and boll weight, lint percentage and seed index, breaking through the bottleneck of yield improving the yield and fiber quality traits in breeding, breeding of high yield and quality of hybrid cotton varieties, giving service for Yangtze River cotton region.
