| 摘 要： | 应用高稳系数法分析玉米穗部性状的效应和稳定性,研究玉米品种穗部性状变异与高产稳产性的关系.结果表明:供试玉米品种之间的每穗粒数、千粒重、每穗粒重、每穗行数及每行粒数差异显著或极显著.玉米品种产量与每穗粒数、千粒重和每穗粒重相关极显著.玉米品种产量高稳系数与千粒重高稳系数的相关显著,与每穗粒重的相关不显著,玉米品种产量的稳定性主要与千粒重的稳定性相关.每穗粒重的高稳系数与每穗粒数高稳系数相关显著,而与千粒重的高稳系数相关不显著.

| Abstract: | In order to study the relationship of ear characters and stable high yield of maize varieties,the effects and stability of maize ear characters were analyzed by high stability coefficient(HSC).The results indicated that:there were significant differences among maize varieties in aspect of seeds per ear,the weight of a thousand seeds,seed weight per ear.All the correlation coefficients of maize yield with the seeds per ear,the weight of a thousand seeds,seed weight per ear were significant.The HSC correlation coefficients of maize yield with the weight of a thousand seeds was significant,while it was not correlated with seed weight per ear.The yield stability of maize varieties was mainly correlated with the weight of a thousand seeds.The HSC of seed weight per ear was mainly correlated with that of seeds per ear,but not with the weight of a thousand seeds. |
