摘　　要：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153.59～222.63 μm,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.In order to obtain new superior cultivars of litch,field selfing,conventional and distant hybrid breeding were conducted.The results were as follows： the pollen germination rate of 7 male cultivars reached to 47.08% to 69.12% after culturedfor 10 hours,pollen tube length was 153.59 ~ 222.63μm,fully able to meet the requirements of artificial pollination. Eventuallyobtained 26 of YA1 selfing seedlings, 4 of Jiaohesanyuehong and 97 of Maguili. 149 of hybrid seedlings were obtainedfrom 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.
