新梨7号授粉试验初报

Preliminary study on pollination of Xinli No.7 (Pyrus bretschneideri Rehd.)

20 0 1与 2 0 0 3年 ,选用当地主栽的香梨和香梨常用的几个授粉品种对新梨 7号做了授粉试验。结果表明 :巴梨、苹果梨因花期太晚 ,不能作为自然授粉树配置 ,其余供试各品种从物候期来看均可作为新梨 7号的授粉树。各组合第一次落果发生在授粉后 10余天 ,除香梨、早酥和慈梨外 ,其余组合均未发生明显的 6月落果。各组合果重、果心比、可溶性固形物含量之间存在极显著差异。新梨 7号果实品质性状主要由母性基因控制 ,花粉直感效应并不明显。综合各性状 ,我们初步认为砀山梨、茌梨、阿拉尔黄梨和鸭梨作新梨 7号授粉树比较理想。

In 2001 and 2003,the pollination study of Xinli No.7 was respectively conducted with such varieties as Xiangli and so on. The result was as follows: except for Battlett and Pingguoli with too late phenological period ,other varieties could act as natural pollination trees of Xinli No.7. The first fruit falling was observed 10 days after pollination. Except for such combinations of Xiangli, Zaosu and Cili,.less obvious June fruit falling happened to other combinations. Single fruit weight,fruit core index, total soble solid were most significantly different among combinations. Main fruit economic traits were mainly detemined by female genes with less obvious xinity.Above all,it was believed that Dangshanli,Chili,Alarhuangli and Cili were iderl pollination varieties to Xinli No.7.
