采用随机区组设计3次重复,对新疆新选育的9个极早熟玉米品种开展品种区域试验,通过田间鉴定、考种、测产等试验研究,结果表明:参试品系HJ2123的植株性状、百粒重、单穗产量等表现较好,产量达787.82 kg/666.7 m2,位居第1;户单77产量达779.3 kg/666.7m2,位居第2,这2个品种表现既高产又早熟,可作为南疆地区麦后复播玉米品种。
A total of 9 extremely precocious maize cultivars newly selected in Xinjiang were used to carry out regional trials with three replicates of randomized block design. The field trials, test and production test were carried out. The results showed that the plant characters of HJ2123, The output of 100-grain weight and single spike was better, with the yield reaching 787.82 kg / 666.7 m2, ranking No. 1; the output of household 77 reached 779.3 kg / 666.7 m2, ranking No. 2, which showed both high yield and precociousness , Which can be used as corn replanting maize variety in southern Xinjiang.
