一批早熟棉花材料在江西的表现与分析

Identification and Screening of the New Introduced Early- maturing Cotton Materials in Jiangxi

为选育适宜江西棉区种植的早熟棉品种,实行棉花生产机械化,并大力推行棉田两熟或多熟种植模式,以稳定江西植棉面积,提高棉田效益。江西省棉花研究所于2013年在其科研基地对征集引进的26份早熟棉花材料进行鉴定。结果表明:该批材料早熟性整体表现较好,抗棉铃虫性较好,单株成铃数变幅较大。经综合比较分析,筛选出综合表现较好、性状特征较符合机采要求的WH1、邯郸686和抗虫花株3份材料,可重点加以利用。

In order to foster suitable for machine adopt early-maturing cotton varieties, and vigorously carry out two planting or multiple cropping patterns in cotton field to stable cotton planting area,and improved the efficiency of the cotton production,thsis unit had collected all kinds of early-maturing cotton materials 26 on a national scale to carry out ecological adaptability experiment since 201 3 . The result indicated most of materials were the early maturing type,and the cotton boll-worm resistance was better,and owned a higher variation range on the boll setting . The comprehensive comparative analysis, good comprehensive performance,the traits a meet the requirements of the machine adopt WH1 ,handan 686 and insect-re-sistant strains of three materials,may be key to use .
