怒江流域杧果种质资源果实性状评价与分析

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。

Evaluation and Analysis of Fruit Characters of Mango Germplasm Resources in the Nu River Valley

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.
