摘要
杂208是山西省农业科学院棉花研究所选育的高产、优质、多抗棉花杂交新品种。该品种2003—2004年参加山西省南部中熟棉区新品种区域试验,平均皮棉产量1 582.5 kg/hm2,较对照晋棉31号增产39.74%;2005年进行生产试验,平均皮棉产量1 987.5 kg/hm2,较对照增产22.46%。分析探讨了杂208的选育过程和遗传基础,并介绍了其特征特性、产量表现和栽培要点。
Za 208 hybrid cotton was bred by Institute of Cotton,Shanxi Academy of Agricultural Sciences.It is a new cotton hybrid variety of high-yield,fine quality and multiresistance.Its average yield of lint was 1582.5kg/hm2 in the middle-maturing cotton regional test of new varieties in southern Shanxi from 2003 to 2004 years,and the yield increased by 39.74% compared with Jinmian31;in production test in 2005 the average lint yield 1 987.5 kg/hm2,increasing by 22.46%.This paper analyzed the breeding process and genetic basis of the Za 208,and described its characteristics,production performance and cultivation techniques.
