摘要: 为加强梨种质资源优异性状的挖掘和利用,对853份梨果实的石细胞含量进行检测分析。结果表明,石细胞含量为0.043%~4.764%,平均值为0.812%,变异系数为68.72%,中位数0.694%。筛选出石细胞含量小于0.1%的极少种质资源17份,石细胞含量大于2.5%的极多种质资源10份。筛选出的特异资源可用于梨品种选育、遗传群体构建和木质素合成代谢研究等,提高种质资源的利用效率。

关键词: 梨, 石细胞含量, 种质资源

Abstract: In order to strengthen the exploitation and utilization of excellent characters in pear germplasms,the stone cell content of 853 pear flesh was detected and analyzed.The results showed that,the stone cell content was 0.043%~4.764%,the average value was 0.812%,the coefficient of variation was 68.72%,the median value was 0.694%.17 extremely low germplasm resources with stone cell content less than 0.1% and 10 extremely high germplasm resources with stone cell content more than 2.5% were screened out.These specific resources could be used in pear breeding,genetic population construction and lignin metabolism research,so as to improve the utilization efficiency of germplasm resources.

Key words: pear, stone cell content, germplasm resources
