高EGCG茶树品系杂交技术研究

doi:10.13305/j.cnki.jts.2012.05.012

Abstract

Abstract: 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.

Key words: high EGCG content tea lines, hybridization pollination technique, hybridization compatibility, seedling rate
