本试验是为了在玉米杂交种中选出一个高产、优质、抗逆性强的杂交种进行玉米杂交品种比较试验。本实验对玉米杂交种DK743、901号、华玉5号和SC704(CK)的产量,穗粒质量等农艺性状进行了方差分析和平均产量相互比较。试验结果表明,杂交种DK743比对照SC704(CK)平均产量高于为1%,每穗粒质量低于为1%,杂交种901的平均产量比SC704(CK)低于为34%,每穗粒质量低于为37%,杂交种华玉5号平均产量比对照SC704(CK)低于为15%,每穗粒质量低于为7%。分析结果表明,3种杂交种中杂种DK743在农艺性状、产量、每穗粒质量接近对照SC704(CK),杂交种901和华玉5号的产量、每穗粒质量低于对照SC704(CK)。
This experiment is to select a high-yielding, high-quality, high-yielding hybrids from maize hybrids for comparative testing of maize hybrids. In this experiment, the variance analysis and the average yield of corn hybrids DK743,901, Huayu5 and SC704 (CK) yield and grain quality were compared with each other. The results showed that the average yield of hybrids DK743 was higher than 1% for SC704 (CK), less than 1% per panicle, the average yield of hybrid 901 was 34% lower than that of SC704 (CK) The average yield of the hybrid Huayu 5 was 15% lower than that of the control SC704 (CK) and the grain weight was less than 7%. The results showed that the yield of the hybrid DK743 in three kinds of hybrids was almost the same as that in the control SC704 (CK), hybrid 901 and Huayu 5, and the grain weight per panicle was lower than that of the control SC704 (CK) .
