对国家果树种质福州枇杷圃内不同来源地的172份枇杷种质资源进行了果实的风味、剥皮难易、果肉颜色、心皮质地、种子形状、种皮颜色、种皮开裂、种子斑点、种子基套大小、果肉化渣程度、果肉质地和汁液等12个描述性状的多样性分析,结果表明:枇杷种质的12个果实描述性状变异系数范围为28.34%~78.75%,Simpson多样性指数为0.349~0.834,果实风味、果肉质地和果肉颜色的多样性指数较高,具有丰富的多样性,种皮开裂和种子形状的多样性指数较低,多样性较差。在不同果肉类型当中,红肉类型枇杷种质的果肉化渣程度的Simpson多样性指数比白肉类型高3.2倍,而种皮开裂的Simpson指数比白肉类型低0.196,其余描述性状的Simpson指数相差不大。
A total of 172 accessions of loquat germplasm from different origins of national fruit tree germplasm in Fuzhou were studied for their fruit flavor, peel color, cortex texture, seed shape, seed coat color, seed coat cracking, seed blotch, The results showed that the coefficient of variation of 12 characters of loquat germplasm ranged from 28.34% to 78.75%, and the Simpson diversity index 0.349 ~ 0.834. The diversity of fruit flavor, texture of flesh and color of flesh was high, with rich diversity. The diversity indices of seed coat cracking and seed shape were lower and the diversity was poor. Among different flesh types, the Simpson index of pulp flesh of red loquat germplasm was 3.2 times higher than that of white flesh, while the Simpson index of seed coat fissures was 0.196 lower than that of white flesh, while the Simpson indices of the other descriptive traits were not different Big.
