摘　　要：对国内外128份枇杷种质资源的3个测量性状(种子数、种子重、种子瘪粒数)和5个描述性状(种子形状、种皮颜色、种子斑点、种子基套大小和种皮开裂)进行了鉴定评价。结果表明:枇杷种质资源的种子测量性状表现出较丰富的多样性,集中表现为:种子数2～4粒,种子重1～3g,瘪粒较少;种子描述性状则较多地表现为三角体形、浅褐色、斑点少、基套小、不开裂。和云南枇杷种质资源相比,福建枇杷种质资源的种子个体较大,数量较多,出现瘪粒概率较大,种子形状、种皮颜色、种子斑点、种子基套大小和种皮开裂的分布表现较集中,这可能是枇杷种质资源种子性状的进化趋势,表明云南枇杷种质资源的遗传多样性更为丰富。此外,还就枇杷种质资源种子数和种子重的分级标准进行探讨,为今后更科学地开展枇杷种质资源的鉴定评价和利用提供理论依据。The seed charcter of Loquat germplasm resource was studied,including seed number,seed weight,abortive seed number,seed color,size of seed basic sheath,number of spots on seed surface,seed shape,and seed dehiscence.The result showed that,there was abundant in diversity on the 128 loquat germplasm seed characters.The main metrical character of Loquat germplasm seed was 2~4/fruit,1~3 g/seed,few abortive seed.And the described character was triquetrous,beige,few spot,small basic sheath and indehiscent.To Yunnan loquat,the seed was bigger size,more number and few abortive in Fujian,and described character tended to concentrate,which showed be loquat germplasm evolutionary trends.In addition to,the grade criteria of seed number and seed weight was advised according to the statistic.
