| 中文摘要: |
| 以‘酥梨’与‘苹果梨’杂交后代群体为试材，测量果心大小、单果重、可溶性固形物等7个指标，分析其分布规律，以期为梨遗传育种提供参考依据。结果表明：杂交后代单果重普遍较小，在100~120g区间分布最多，总体呈正态分布趋势。果形指数在0.98~1.04和1.07~1.19为集中分布区，果形与母本‘酥梨’相近。杂交后代果形指数、单果重、可溶性固形物含量、果心大小总体呈正态分布趋势，属数量遗传性状。果皮颜色以传统梨的黄色为主，占总数的59.42%，倾向于母本的果实颜色。后代果柄出现肉质化，果实的脱萼率为38.65%。 |

| In order to provide a reference for pear genetic breeding, 7 indexes, such as fruit core, single fruit weight and soluble solids, were measured in the hybrid progenies of ‘Suli’ and ‘Pingguoli’. The results showed that the single fruit weight of the hybrid progenies was generally small and distributed most in the 100 ~ 120g range, with a general normal distribution trend.The fruit shape index ranged from 0.98 to 1.04 and from 1.07 to 1.19 respectively. The fruit shape was similar to that of ‘Suli’.The fruit shape index, single fruit weight, soluble solids and fruit core of the hybrid progenies showed a normal distribution trend, which was a quantitative genetic trait. The yellow color of the traditional pears was the main color, accounting for 59.42% of the total, which tended to be the color of the mother pears. The fruit peduncles were fleshy and the rate of calyx removal was 38.65% . |
