据《东北农业大学学报》2014年第3期《西瓜种质资源果实主要数量性状的主成分分析》(作者王志强等)报道,以29份西瓜种质资源为试验材料,采用主成分分析方法分析西瓜果实重量、果皮硬度、果实长度、果实宽度、瓜内种子数和中心糖含量等6个主要数量性状,并对参试西瓜材料数量性状的品质表现进行综合评价。遗传多样性研究结果表明,29份材料的6个 According to “Northeast Agricultural University,” 2014 the third period “watermelon germplasm resources of the main quantitative traits of the principal component analysis” (by Wang Zhiqiang et al.) Reported to 29 watermelon germplasm resources as the experimental material, the use of principal component analysis Watermelon fruit weight, pericarp hardness, fruit length, fruit width, the number of melon seeds and the center of the sugar content of six major quantitative traits, and quantitative evaluation of the quantitative performance of watermelon materials. The results of genetic diversity studies showed that 6 of the 29 materials
