摘　　要：2011年10月在浙江省桐庐县美国山核桃Carya illinoensis种质资源园内采集9个单株的9年生‘马罕’C.illinoensis ‘Mahan’果实,测定坚果质量、果长和果径。2012年1月播种育苗,2015年1月对每株苗的苗高和地径进行测量,2018年1月再次测量。结果表明,‘马罕’果实性状在不同单株间具有极显著差异(P<0.01);变异幅度最大的是坚果质量,平均变异系数23.91%。不同单株子代间,3年生苗苗高与地径都表现出极显著差异(P<0.01),高径比为显著差异(P<0.05),各子代平均苗高45.95～78.67 cm,平均地径5.75～9.30 mm,平均高径比6.95～8.88;相关分析表明苗高、地径的生长量与其坚果质量显著相关(P<0.05),相关系数分别达到0.63,0.71。6年生苗子代间苗高、地径和高径比均未表现出显著性差异(P>0.05)。综合分析认为,‘马罕’果实性状分化较大,其坚果质量与子代苗木的生长在3年生时显著相关(P<0.05),而在6年生时无显著性差异(P>0.05),其坚果质量对其影响会逐渐减小。In October 2011,nuts of 9 individuals of 9-year Carya illinoensis‘Mahan'were collected in Tonglu of Zhejiang province.Determinations were implemented on nut mass,length and width.Sowing and seedling cultivation was carried out in January 2012 in Hangzhou.Seedling height and ground diameter were measured in January 2015 and 2018.The result showed that it had great differences of fruit characters among different individuals(P<0.01).The greatest variation was the nut mass with mean coefficient of variance of 23.91%.There was extremely evident difference of height and ground diameter of 3-year seedlings among different individuals,while evident of height ground diameter ratio.The average seedling height of different progeny was 45.95-78.67 cm,average ground diameter of 5.75-9.30 mm and average height/ground diameter ratio of 6.95-8.88.Correlation analysis demonstrated that the growth of seedling height and ground diameter was significantly correlated with the mass of nut,withcorrelation coefficient of 0.63 and 0.71.There was no significant difference in height,ground diameter and height/ground diameter ratio of 6-year seedlings among different progeny.Comprehensive analysis indicated that‘Mahan'had a large differentiation of fruit traits.The mass of nuts was significantly correlated with the growth of 3-year seedlings,but lower down of 6-year seedlings.
