对224份枇杷种质果实11个性状的分布情况及性状间的相关性进行了分析研究,结果表明:(1)枇杷种质资源果实的单果重、可溶性固形物含量、可食率、果实纵经、果实横径、果实侧径、果形指数、萼片长度、萼片基部宽度、萼筒宽度和深度等11个性状存在广泛的分布,变异系数在11.81%~48.92%之间,分布区间以单果重为最大,果形指数为最小;(2)果形指数不能完全反映果实形状;果形指数在0.91~1.10之间的种质果形最为丰富;(3)单果重与果实纵径、果实横径、果实侧径、萼片长度、萼片基部宽度、萼筒深度、可食率及果形指数等8个性状呈极显著正相关,与可溶性固形物含量呈极显著负相关;可食率与单果重、果实纵径、果实横径、果实侧径、萼片长度、萼片基部宽度、萼筒深度及果形指数等8个性状呈极显著正相关,与可溶性固形物含量呈显著负相关;果形指数与果实纵经、单果重、萼筒深度、可食率等4个性状呈极显著正相关,与可溶性固形物含量呈极显著负相关。
The distribution of 11 traits in 224 loquat germplasms and their correlations were analyzed. The results showed that: (1) The fruit weight, soluble solids content, edible rate, fruit length The results showed that 11 traits such as diameter of fruit, lateral diameter of fruit, fruit shape index, length of sepals, width of sepal base, width and depth of calyx were widely distributed with coefficients of variation ranging from 11.81% to 48.92% (2) The fruit shape index can not fully reflect the shape of the fruit; The fruit shape index of 0.91 to 1.10 is the most abundant among the fruit types; (3) The fruit weight and fruit length, fruit There were extremely significant positive correlations among 8 traits, such as diameter, diameter of fruit, sepal length, base of sepal, calyx tube depth, edible rate and fruit shape index, and significant negative correlation with soluble solid content. Edible Fruit weight, diameter of fruit, diameter of fruit, lateral diameter of fruit, length of sepals, width of base of sepals, depth of calyx tube and fruit shape index. There was a significant negative correlation between soluble solids content and fruit weight. Shape index and fruit longitudinal , Fruit weight, calyx tube depth, edible rate and other four traits were highly significant positive correlation, and soluble solids content was extremely significant negative correlation.
