漾濞大泡核桃授粉品种选择试验

Study of Pollinizer Screen-out for Juglans sigillata Variety Yangbidapao

通过对大理白族自治州主栽的漾濞大泡核桃、三台核桃、娘青核桃、圆菠萝核桃、漾杂2号核桃5个核桃品种雌雄花期调查,比较了供试品种的雌雄花期,并以漾濞大泡核桃为母本,其他品种为父本进行授粉亲和性试验,统计分析各品种授粉后坐果率及保存率。结果表明,平均坐果率均在70%以上,其中坐果率和保存率最高的为漾杂2号,分别为93.25%、73.01%,但其雄花期与漾濞大泡核桃的雌花期不一致;表现最差的为圆菠萝核桃,坐果率及保存率分别为72.29%、55.37%。娘青核桃是漾濞大泡核桃的最佳授粉品种,花粉亲和性较好,雄花期与漾濞大泡核桃雌花期一致,坐果率及保存率分别为91.67%、71.81%。本项试验结果可为漾濞大泡核桃的增产、稳产以及选择最佳授粉品种提供参考。

Flowering period of female and male of five varities of Juglans sigillata, including Yangbidapao, San- tai, Niangqing, Yuanboluo and Yangza No. 2 were investigated and compared. Pollination compatibility experiment was conducted which taking Yangbidapao as female parent and other cultivars as male parent. Fruit setting rate and preserving rate after pollinating were analyzed. The results showed that average fruit setting rate was over 70 %. The highest fruit setting rate and preserving rate was 93.25 % and 73.01% from Yangza No. 2, but its male flow- ering period was inconsistency with female flower of Yangbidapao. The poorest performance was Yuanboluo with fruit setting rate of 72.29 % and preserving rate of 55.37 %. Niangqing was the best pollination variety for Yang- bidapao because of its good pollination compatibility, same flowering period, high fruit setting rate and preserving rate of 91.67 % and 71.81% respectively. The test results provided the reference for production and selection of pollination varieties of Yangbidapao.
