辽栗10号、辽栗15号、辽栗23号选育研究

Studies on selecting and breeding of LiaoLi No.10, LiaoLi No.15 and LiaoLi No.23

通过人工有性杂交,选育出辽栗10号、辽栗15号、辽栗23号3个新品种。试验结果表明,辽栗10号、15号、23号在凤城地区4～6年生嫁接树,平均产量分别达4372kg/hm2、3052kg/hm2、3300kg/hm2,同时具有品质优、抗虫性、抗寒性与适应性强等特点。新品种已在辽宁凤城、庄河、桓仁等地示范推广面积3000hm2,新增产值10920万元,取得了显著的经济效益和社会效益。

Through artificial cross-breeding, three new chestnut varieties, namely, LiaoLi No.10, LiaoLi No.15 and LiaoLi No.23 are selected. The trial results show that the average annual yield of the 4-to 6-year-old grafted trees of LiaoLi No.10, LiaoLi No.15 and LiaoLi No.23 can reach 4 372 kg/hm2, 3 052 kg/hm2 and 3 300kg/hm2 respectively in Fengcheng area. Meanwhile, three new varieties are of such characteristics as fine quality, insect resistancy, cold resistancy and high adaptability. In the demonstration area of 3 000 hm2 at Fengcheng, Zhuanghe and Huanren in Liaoning province, 109.20 million yuan of extra output value has been produced with significantly economic and social benefits.
