摘要
对10玉米个杂交组合进行了产量和农艺性状的比较。结果表明,9个供试组合中有沈4002、沈4003的产量显著高于对照豫玉22,其农艺性状表现好,穗行数、行粒数、千粒重相互协调较好,可以在河南省进一步试验和示范。株高与产量也有一定的关系,在选育新组合时应选植株中等偏上的组合,有利于产量的提高。
In this study, 10 crossing combinations of corn were compared in yields and economical characteristicss. The results showed that the yields of Shen 4002 and Shen 4003 were significant higher than the control Yuyu 22, and economical characteristics, such as row number per ear, grain number per row, thousand seed weight also were better. The yield was related with plant high, and the combinations with higher plant than average high would bring higher yields.
