【摘要】 选用黄早四及其衍生系共30份自交系为材料,通过在不同生态条件下两年三点的大田试验,对农艺性状的稳定性进行研究。结果表明,农艺性状在哈尔滨表现最好,有利于产量水平的发挥;农艺性状中受GEI影响程度最大的是百粒重,其次为单株产量。文章对黄早四及其衍生系产量的稳定性比较得出高产稳产型自交系,同时对黄早四及其衍生系的改良方向进行了探讨。更多还原

【Abstract】 Huangzaosi and its derived lines were selected as experimental material to research the stability of agronomic traits.The results showed the agronomic traits had the best performance in Harbin,and Harbin is good for yield.The interaction of genotype and environment(GEI) has the greatest significant influence on 100-grain weight,and yield per plant followed.Inbred lines which had high and stable yield was chosen throw the comparison,this article discussed on the improvement of Huangzaosi and its derived lines.更多还原
