摘要：In order to obtain new superior cultivars of litch,field selfing,conventional and distant hybrid breeding were con-ducted. The results were as follows: the pollen germination rate of 7 male cultivars reached to 47.08% to 69.12% after cultured for 10 hours,pollen tube length was 153.59 ~ 222.63μm,fully able to meet the requirements of artificial pollination. Eventu-ally obtained 26 of YA1 selfing seedlings, 4 of Jiaohesanyuehong and 97 of Maguili. 149 of hybrid seedlings were ob-tained from Maguili × Jiaohesanyuehong, 194 of that from Maguili×Nuomici, 158 from Maguili×Guiwei, 121 from Maguili× Wuheli and 52 from Ziniangxi×Wuheli. There is 32 distant hybrid seedlings from Shixia longan×Ziniangxi.%为获得荔枝新优品种开展了荔枝田间自交、常规杂交及远缘杂交育种，结果表明：7个父本品种花粉培养10 h 后的发芽率为47.08%～69.12%，花粉管长度为153.59～222.63μm，完全能够满足人工授粉的要求；人工授粉后最终共获得 YA1自交苗26株，焦核三月红自交苗4株，马贵荔自交苗97株；马贵荔×焦核三月红获得杂种苗149株，马贵荔×糯米糍获得194株，马贵荔×桂味获得158株，马贵荔×无核荔获得121株，紫娘喜×无核荔获得52株，远缘杂交组合石硖龙眼×紫娘喜获得32株。
