Abstract
The field experiment,weak-gluten wheat cultivar Yangmai 9 and medium-gluten wheat cultivar Yangmai 12 served as materials,was conducted to study the effects of planting density on yield and quality of individual and population of the wheat cultivars.The results showed that,(i) to coordinate the conflict of group and individual development,the good quality and high yield population structure could be established easily at the density of 2.40 million basic seedlings/hm2 for Yangmai 9 and 1.50 million basic seedlings/hm2 for Yangmai 12;(ii) in the the comparison of two established good-quality and high-yield populations,these indices of the weak-gluten wheat cultivar Yangmai 9,including the dry matter mass after booting stage,total amount of accumulated dry matter after flowering,the number of maturity stems,plant height component index,the ratio of rachis internode length to stem length,and the ratio of the length of rachis internode plus head to plant height,were lower than those of medium-gluten wheat cultivar Yangmai 12,but the peak number of seedlings and the descent speed of leaf area index after flowering in Yangmai 9 were higher than in Yangmai 12.
