摘　　要：对213份枇杷种质果实的纵径、横径、侧径、纵径/横径、纵径/侧径及横径/侧径等6个果径性状进行了鉴定评价,结果表明:枇杷果实的纵径、横径和侧径分布均符合正态分布,横径和侧径的频数分布相似,在4.00cm以上的频数分布均显著低于果实纵径;来源于云南和贵州的枇杷种质果实纵径、横径和侧径与其他地区差异极显著,不同来源地种质的横径/侧径差异不显著;果实纵径/侧径、横径/侧径不能完全反映果实形状。The fruit vertical, transverse and lateral diameter, vertical/transverse, vertical/lateral and transverse/lateral size of 213 loquat accessions were studied. The results showed that, distributions of fruit vertical, transverse and lateral diameter were skewness; distribution frequencies of fruit trans- verse and lateral diameter were similar, and the distribution frequency above 4. 00cm was lower than that of fruit vertical diameter significantly; fruit vertical, transverse and lateral diameter from Yunnan and Guizhou province were different significantly compared with other germplasm accessions and there was no significant difference in transverse/lateral size among different germplasm accessions; vertical/ lateral and transverse/lateral size could not reflect fruit characters completely.
