摘　　要：【目的】评价不同陆地棉品种棉籽的营养品质,为棉花综合品质改良育种提供资源。【方法】测定14个陆地棉品种的棉籽营养成分,包括籽指、含水量、蛋白质及粗脂肪等种子质量有关的指标。【结果】不同陆地棉品种间含水量、蛋白质、粗脂肪、籽指差异明显,变幅依次为籽指、含水量、蛋白质,粗脂肪。籽指最高的是新陆早35号10.23 g,最低的是Y1164 7.78 g;XND1584和r1164的含水量最高,新陆早38号含水量最低;短节岱种子的蛋白质含量最高22.59 mg/g,塔什干1号的最低3.84 mg/g;关农1号种子与短节岱种子的粗脂肪含量最高,分别为51.35%、50.99%,XND1586的最低26.41%。【结论】把14份材料聚类为四大类。材料中含高油高蛋白材料1份,高油分材料4份,高蛋白材料5分。【Objective】To evaluate the nutritive quality of different upland cotton varieties and provide resources for comprehensive quality improvement breeding of cotton.【Method】The nutrient contents of cottonseed in 14 upland cotton varieties were determined,and the indicators related to seed quality such as seed index,water content,protein and crude fat were determined,too.【Result】The water content,protein,crude fat and seed index of different upland cotton varieties were significantly different.The order of variation was seed index,water content,protein and crude fat.The highest seed index was Xinluzao 35,10.23 g,the lowest was Y1164,7.78 g;the water contents of XND1584 and r1164 were the highest,the water content of Xinluzao 38 was the lowest;the protein content of short node seed was 22.59 mg/g,and that of Tashkent 1 was the lowest,3.84 mg/g;The crude fat content of Guanong No.1 seed and P.japonicus seeds was the highest,which was 51.35 and 50.99,respectively,and XND1586 was the lowest 26.41%.【Conclusion】The comprehensive seed index,water content,protein and crude fat clustered 14 materials into four categories.It has been identified that the test materials contain one high oil and high protein content material,four high oil content materials,and five high protein content materials.
