영문 초록

For breeding of new Korean tea cultivars, It is very important to get basic informations on cross fertility of Korean native tea plants. Results of this investigation are summarized as follows. In Japan cultivar. 'Yabukita' and Korean .native tea plant, the rate of fertilization from strictly selfing, selfing between intra-plants and sibbing between inter-plants were 3.2, 3.1 and 5.6%, respectively. In Posong native tea plant, the rate that of fertilization from strictly selfing, selfing between intra-plants and sibbing between inter-plants were 2.9, 4.2 and 11.2%, respectively. Pollens were germinated on the stigma from 2 hours after pollination and pollen tubes grew into the style from 12 hours after pollination and into the ovary from 48 hours after pollitnation. The rate of fertilzation of 'Daewonsa native tea plant'X'TTES No 12' was 50%, whereas the reciprocal cross 'TTES No 12' X 'Daewonsa native tea was 23.3%. The average rate of fertilzation from all crosses was 19.8% and 'Yabukita' X'Daewonsa native tea and 'Yabukita'X'Bulamsa native tea were 50 and 42.2%, respectively. The number of seeds per fruit was 1.8 and and seed weight was 1.6g.
