摘 要 2005~2011年,对怒江流域杧果种质资源进行收集及鉴定评价(主要包括果实形状、果实重量、果皮颜色、果肉颜色、胚性、可食率、可溶性固形物和风味等)。结果表明:在调查的50份杧果种质资源中,无论是从果实的大小、颜色、胚性等方面都存在着一些优良的种质资源;在杧果果实品质性状间相关性分析发现,单果重、果实长度、果实宽度、种子长度间的相关系数均呈极显著正相关,可食率和种子重量间的相关系数呈显著正相关,可溶性固形物除与果宽和果厚呈显著负相关外,与其他性状间的相关系数均未呈现显著相关。怒江流域杧果种质资源存在着丰富的优异性状,这些优异性状为杧果的品种选育及品种改良创造了良好的基础。

Abstract During 2005 to 2011, mango germplasm of Nu River Valley were collected and evaluated, including fruit shape, fruit weight, fruit color, flesh color, embryonic, edible rate, soluble solids, flavor, and etc. The results showed that in the 50 mango germplasm investigation, whether it is from the fruit the size, color, embryo, there are some excellent germplasm in fruit quality traits; correlation analysis showed that the correlation coefficients of mango fruit weight, fruit length, fruit width, seed length were showed a significant positive correlation, the correlation coefficient and the edible rate between seed weight was positively correlated, soluble solids removal and fruit width and fruit thickness was negatively correlated, and the correlation coefficient between the other traits were not significantly related. Mango germplasm in Nu River valley has excellent characters of rich, these excellent characters has laid a good foundation for breeding and variety improvement of mango.

杧果(Mangifera indica L.)为漆树科杧果属植物,是重要的热带、亚热带水果,享有“热带果王”之美誉,为世界五大名果之一,分布于几乎所有的热带、亚热带国家和地区[1]。杧果种质资源丰富,但由于杧果品种国际化,很多具有明显地方特色的品种出现了严重的丢失,因此杧果资源的收集及鉴定评价显得尤为重要[2]。云南省是我国野生杧果分布的主要省份之一。2005~2011年我们对怒江流域杧果种质资源进行收集及鉴定评价,发现了怒江流域分布有很多特异性状的杧果种质资源,这为杧果品种选育及品种改良创造了良好的条件。
1 材料与方法
1.1 材料
供试材料为从怒江流域收集保存的50份杧果资源,于2005~2011年在各个资源果实成熟期分别测定果实形状、果重、果皮颜色和厚度、果肉颜色、可食率、可溶性固形物、风味等,并对50个样本进行统计分析。……
