摘要
对关中地区常见的11个鲜食杏品种连续3 a的花型数量分布进行了调查分析,并计算了遗传力.结果表明,①不同杏品种及不同枝型的花型分布比例存在着显著差异,11个品种中以沙金红杏和争魁的有效花比例最大,分别达到76.59%和53.14%,具有较强的丰产潜力,属丰产型品种;串枝红杏、红杏、猪皮水杏、王八达杏、荷包杏和日本杏有效花比例在21%～37%之间,增产潜力中等,属于中产型品种;旬阳荷包杏、张公园杏和西农20号杏有效花比例在20%以下,增产潜力较差,属低产型品种.②杏树有效花比例主要受遗传因素所控制,连续3 a的遗传力分别达86.05%、81.97%和93.66%,环境因素对花型比例影响较小.
Quantity distribution of different-types of flowers of Armeniaca vulgaris varieties were investigated in the last three years and the heredity was caleulated. The results indicated that: ① There were great differences among four types of fruit branches, formal flower ratio of 'Shajinhong' and 'Zhengkui' were maximum,which were as high as 76.59% and 53.14% belonging to high yield variety; formal flower ratio of Chuanzhihong, Hongxing, Zhupishuixing, Wangbadaxing, Hebaoxing and Ribenxing are between 21%～37%, the productive potentials were secondary;formal flower ratio of Xunyanghebaoxing, Zhanggongyuanxing and Xinong20 are below 20%, which belonged to lower yield variety.②Formal flower percentage of A. vulgaris was mainly controlled by heredity(%), which came to 86.05%, 81.97% and 93.66% in the last three years, the influence of environment was little.
