Study on Plant Height of Wheat
摘要
Abstract
To enhance breeding predictability and selection efficiency,the problem of wheat height was discussed.Breeding of the dwarf and semi -dwarf varieties was the development tendency of modern wheat breeding.The negative impacts of over-dwarf and the beneficial effects of moderate height were analyzed. The ideal height range was not certain,which should be determined based on production conditions and yield level.On the basis of appropriate height,we should focus on improving the quality of stem and the quantity of root,screening rational group composition and canopy structure to further optimize the comprehensive agronom-ic traits of wheat.Then the ideal combination of wheat morphological traits on higher basis could be realized to improve the yield potential and make a breakthrough.关键词
