Relationship between ear characters and high-yield stability of maize varieties

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.
