为了在自育的玉米杂交组合中选出一个高产、优质、抗逆性强的组合,特进行了玉米杂交组合比较试验。对39个自育玉米杂交组合与目前在新疆广泛推广的早熟杂交种新玉9号作为对照进行了比较试验。39个自育杂交组合能不能超过对照的杂交种新玉9号,对产量进行了间比法分析。间比法分析结果表明,总共10个自育杂交组合的产量超过对照杂交种新玉9号增幅为3.5%~41.1%。综合产量构成因素来看,可以对06×07、59×07、天4×07等几个自育杂交组合进行进一步的分析研究。
In order to select a high-yielding, high-quality and strong-resistance combination among self-bred maize hybrids, a comparative experiment was conducted on the hybridization of maize. A comparative experiment was carried out on 39 self-bred maize hybrids and the early maturing hybrid Xinyu 9 currently widely popularized in Xinjiang. 39 hybrid combinations can exceed the control hybrid Xinyu 9, the yield was analyzed by the ratio method. The results of inter-specific analysis showed that the yield of a total of 10 self-bred hybrid combinations exceeded that of the control hybrid Xinyu 9 by 3.5% -41.1%. Integrated yield components, you can 06 × 07,59 × 07, days 4 × 07 and several other self-breeding cross-combinations for further analysis.
