滇西北地区梨主栽品种花粉的亲合性研究

Study on Pollen Compatibility of Main Varieties in Northwest of Yunnan

选择玉香梨、红雪梨、早酥梨、脉地湾梨4个滇西北地区梨主栽品种进行花粉亲合性试验。3a的试验结果表明,除早酥梨外,其它3个品种自花授粉坐果率低,红雪梨与脉地湾梨花粉亲合性差,玉香梨、红雪梨、富源黄梨3个品种间花粉亲合性好,可以互相作为授粉品种。

The experiment of pollen compatibility on 4 pear varieties (Yuxiang pear, Hongxue pear, Zaoshu pear and Maidiwan pear) which are the main varieties in the northwest of Yunnan were carried out. The results showed that except Zaoshu variety, three varieties had low fruit setting rate due to self-pollination; the combination between Hongxue pear and Maidiwan pear was not good , and the combinations among Yuxiang pear, Hongxue pear and Fuyuanhuang pear were suitable.
