摘要
利用1年多点试验联合方差分析方法,对2014年参加新疆东疆地区杂交棉区域试验的品种(系)进行丰产性、稳产性和适应性分析,结果表明:以B6丰产性最好,皮棉产量为2565kg/hm2,较对照增产4.59%,丰产主效应值最大,稳产参数方差和变异度较小,为高产稳产性品种。推荐杂交棉B6进入下一年度的区试或生产试验。
Uing the complex Vavieties variance analysis method of multi - location one year experiments, the yield abili- ty, stable yield stability and adaptability of varieties in hybird cotton regional test were analyzed in Eastern Xinjing in 2014. The results showed that B6 had the best yield ability, its lint yield was 2565 kg/hm2 increaing 4.59% compared with the con- trol ; the main effect value of the yield ability was the highest; the stable parameter variance and variation were smaller; it was a high and stable yield variety; it was recommended to enter the regional test or production test in next year.
