目前,我国栽培芦笋用种仍基本上靠进口,进口的芦笋种子,不但价格昂贵,而且质量差,有不少是越代种,抗病力弱,严重影响了芦笋产量和质量的进一步提高.因此,选育芦笋优良品种,实现种子自给,已成为我国芦笋生产中一个亟待解决的问题.要开展芦笋育种工作,有性杂交是重要手段之一.我们于1987年春选配了若干组合进行杂交试验.试验结果表明,结实率可达95%以上.杂交种的发芽率一般在70%以上.我们认为,搞好芦笋有性杂交应着重注意以下几个环节.
At present, the cultivation of asparagus in China is still basically rely on imports of imported asparagus seeds imported, not only expensive, but poor quality, many of which are more generations, weak resistance, seriously affecting the further improvement of the yield and quality of asparagus. Therefore, the breeding of fine varieties of asparagus, to achieve self-sufficiency of seeds, has become an urgent problem to be solved in the production of asparagus in our country.It is one of the most important means to carry out the breeding of asparagus.We selected some combinations for hybridization in the spring of 1987 Test results show that the seed setting rate can reach more than 95% .The germination rate of hybrids is generally above 70% .We believe that to do asparagus sexual hybridization should pay attention to the following aspects.
