摘要
为利用与创新广西茶树种质资源，选用桂香22号、桂香18号等茶树良种开展人工杂交试验，对其结实率及杂交果实性状进行调查与分析。结果表明：7个杂交组合均有结实，结实率在23．3％～50．6％范围，平均结实率为33．8％；同母本异父本、同父本异母本的组合其结实率差异大，杂交亲和力也不相同；以桂香22号为母本的组合，福云7号与桂香22号的亲和力比云南大叶种、尧山秀绿强；以桂香18号为母本的组合，云南大叶种与桂香18号的亲和力比凤凰八仙单枞、福云7号、福云6号强；以云南大叶种为父本的组合，云南大叶种与桂香18号组合的亲和力比桂香22号强；以福云7号为父本的组合，福云7号与桂香22号组合的亲和力比桂香18号强；综合分析杂交果实的各项性状，初步得出尧山秀绿（父）×桂香22号（母）组合的杂交果实综合性状表现最好，各项指标均超过父母本，差异显菩。
To use and innovate Tea Germplasm Resources of Guangxi, the Guixiang 22, Guixiang 18 tea varieties were selected for the artificial hybridization experiments in which the seed setting rate and hybrid fruit traits were investigated and analyzed. The result showed that the 7 hybrid combinations were strong, seed setting rate in the 23.3 % to 50.6 % range. The average of seed setting rate was 33.8 %, which was different from combination of male female differences, male female differences and hybridization affinity. The affinity of Fuyun 7 and Guixiang 22 was better than Yunnan Dayezhoug and Yaoshan Xiulv in the combination of Guixiang 22 as the female parent. The affinity of Yunnan Dayezhong and Guixiang 18 was better than Fenghang Baxian Dancong, Fuyun 7 and Fuyun 6 in the combination of Guixiang 18 as the female parent. The affinity of Yunnan Dayezhong and Guixiang 18 was better than Guixiang 22 in the combination of Yunnan Dayezhongas the female parent. The affinity of Fuyun 7 and Guixiang 22 was better than Guixiang 18 in the combination of Fuyun 7 as the female parent. The comprehensive analysis of fruit traits of hybrid, preliminary results showed the hybrid fruit of combination with Yaoshan Xiulv （male） and Guixiang 22 （female） comprehensive characters of hybrid combination were best in comprehensive characters. Their various in- dicators in which were more than the parents, there were significant differences.
