| 摘 要： | 1998～ 2 0 0 1年 ,在鲁甸县利用“八五”南北核桃两大种群种间杂交育种评选出的 8个核桃杂交新品系进行区域性试验 ,并采用“八五”选出的 5个新品系作对照。经对 3年生幼树的生长、物候特性、抗寒性能、结果习性以及坚果品质的分析评价 ,综合性状表现较好的有 133、 30 1、 30 3及 30 6等 4个新品系 ,其树体矮化 ,具有早实、丰产、优质、耐寒的优良性能 ,在某些特性上比“八五”选出的新品系更好。可初步确定为适于鲁甸核桃生产的优良杂交品系

| Abstract: | From year 1998 to year 2001, regionalized cultivation experiment of 8 new hybrid strains developed during "Eighth Five year Plan" period were conducted, five new strains selected out also during "Eighth Five year Plan" were chosen as control. After 3 years' cultivation experiment, analysis on the growth, phenophase, cold tolerance, bearing habit and nut quality, the integrated evaluation results implied that four strains coded respectively 133, 301, 303 and 306 had the quality of stunted tree, early fruiting, high yield, good nut quality and cold tolerant, with some characteristics better than the control. Through the cultivation experiment, these four new hybrid strains were preliminarily verified as the suitable strains to be developed in Ludian county. |
