| 摘 要： | 对黄土沟壑区旱地条件下"龙王帽"、"白玉扁"的不同花型数量分布及遗传力进行了分析,结果表明:"龙王帽"的有效花比例高达91.8,具有较大的丰产潜力,宜作为旱地主栽品种;"白玉扁"有效花比例仅为41.2,雌蕊败育率较高,丰产潜力小,仅宜作为授粉品种;花型主要受遗传因素控制(遗传力高达0.99),环境影响较小.

| Abstract: | Investigations on the flower pattern quatity distribution and heredity of the kernel apricot "Longwangmao"and "Baiyubian", cultivated on drought land in loess gully of north Shaanxi, were done. The results indicated that variety'Longwangmao'could be used as a dominant variety on drought land for its higher effective flower ratio ((91.8)%) and greater potential of productivity;'Baiyubian'was the appopriate variety of pollination because its effective flower ratio was only 41.2% as its higher abortion ratio of the famate, and poor productivity. The flower pattern was critically controlled under genetic factors as its heredity was as high as 0.99. |
