摘要
以高EGCG茶树新品系为杂交亲本,利用"剪花瓣显花丝、剪花丝去雄蕊"的人工杂交授粉法,获得了1619个茶树新种质。研究结果表明,采用的杂交授粉技术,操作简便,座果率较高,平均为28.28%±16.26%,最高达46.34%,能够顺利实现茶树杂交育种目标,克服了杂交座果率低的难题;杂交亲本组合对座果率影响最大,其次是杂交苗炭疽病感染率和成苗率,而对种子饱满率和果实种子数影响相对较小。
New tea plant germplasm with high EGCG content was used as hybrid parents. The artificial hybridization pollination technique of ＂cutting petals and thrum shown, cutting thrum and emasculation＂ was used, and the 1619 tea plants new germplasm are obtained. Meanwhile, the results showed： the new hybridization pollination technique showed a high seed setting rate （an average of 28.28%-16.26%, up to 46.34%） and easy operation, cross-breeding goals can be successfully achieved, and the problem of low hybrid seedling rate could be overcomed. Hybrid parental combination had the greatest effect on seed setting rate, followed by anthracnose infection rate and seedling rate of hybrid seedlings, while relatively small effect on plump seed rate and fruit seed number.
