Identification and Evaluation of Korla Pear Bud Sport with Larger Fruit Size
摘要
Abstract
In order to characterize and evaluated the Korla pear bud sports and provide thoeries for fruit production and breeding program,the Korla pear(CK)and its bud sports were used to analyze the botanical morphology,biological characteristics and quality characteristics from 2020 to 2021.The results showed that the bud sports with larger fruit size was obovate-shaped and Korla pear was spindle-shaped;the width of leaf defending cells and the length of flesh cells of the bud sports with larger fruit size were significantly increased.In the process of fruit dynamic development,the single fruit weight and fruit water content of the bud sports with larger fruit size were significantly higher than those of Korla pear.At the fruit ripening stage,the soluble sugar content and sugar-acid ratio of the bud sports with larger fruit size were significantly increased by 78.39%and 84.54%,respectively,and the stone cell content was significantly reduced by 33.33%compared with Korla pear.The bud sports with larger fruit size was analyzed by phenotypic traits and quality characteristics,and it was judged to be the excellent bud variant of Korla pear,which could be used as parental material for pear variety improvement and new variety selection and breeding.关键词
