Effect of Genotype and Environment on Content of Wheat Crude Lipid and Its Stability Analysis

Wheat crude lipid is an important index for classifying wheat,and it often indicates the most appropriate end use of wheat cultivars.In order to discuss the problem of large fluctuations in wheat crude lipid that occurs during commercial wheat production,the variations and stability of wheat crude lipid and its consistency were analyzed using 11 principal high-quality wheat cultivars(varieties) from Shandong Province,which were grown at nine different locations during 2005～2006.The results indicated that the content amplitude of wheat crude lipid was 1.6%~2.7%,and its coefficient of variation ranged from 4.55 to 13.28 among different varieties and locations.Additive main effects and multiplicative interaction(AMMI) analysis showed that there was significant interaction for wheat crude lipid between varieties and growth locations.The genotype effect was the most noticeable,followed by the interaction of genotype and environment.The environmental effect was the least significant.The interactions between variety and location differed greatly,however. Each cultivar(variety) apparently has a specific adaptability to growth location.Therefore,for the successful commercial scale production of high-quality wheat,we should select both the proper cultivar and its most suitable growth locations to meet the desired requirements for wheat crude lipid.
