本研究分析和比较了4个栽培棉种和陆地棉6个品种间的种仁油分和氨基酸成分。在4个栽培棉种中,海岛棉的含油率(39.64％)最高,陆地棉的氨基酸总量(31.17％)亦最高。陆地棉的多种氨基酸含量均比海岛棉、草棉和亚洲棉高,其中增长量较多的是谷氨酸、精氨酸和亮氨酸。6个陆地棉品种的含油率、氨基酸总量和各种氨基酸成分彼此间存在明显的差异。GL—5的氨基酸总量(33.51％)较高,徐州142则有较高的赖氨酸含量(1.5％),是开展种籽品质育种的好材料。由于含油率和氨基酸含量存在极显著的负相关(r=-0.89~(?)),故应根据实际需要确定品质育种的主攻方向。
This study analyzed and compared the kernel oil content and amino acid composition among four cultivars and six cultivars. Among 4 cultivated cotton species, the island oil content was the highest (39.64%) and the total amino acid content (31.17%) was the highest in Upland cotton. Upland cotton variety of amino acid content than sea island cotton, cotton and cotton, cotton, which increased the amount of more glutamic acid, arginine and leucine. There were significant differences among the six cultivars in terms of oil content, total amino acids and various amino acids. The total amino acid content of GL-5 (33.51%) was higher, and Xuzhou 142 had higher lysine content (1.5%), which was a good material for seed quality breeding. Due to the extremely significant negative correlation between oil content and amino acid content (r = -0.89 ~ (?)), The main direction of quality breeding should be determined according to actual needs.
