| Abstract: | In this study,the fruit weight,kernel rate,oil yield and fruit shape index of twenty-one Carya illinoensis varieties which were introduced to Nanjing,were investigated.All traits of these varieties showed significant genetic variation and improvement potential.There were not relationship among the furit weight,kernel rate,oil yield and fruit shape index of twenty-one Carya illinoensis varieties.Through improving general characteristics,six excellent varieties（such as Mahan,Wictita,Sioux,Pawnee,Elliott,Shawnee etc.）were selected by the general coordinate evaluation method.The general characteristics of these six varieties were better than that of varieties of Zhongshan 25#.The genetic gains of the fruit weight,kernel rate,oil yield and the fruit shape index are 53.0%~3.8%,25.9%~8.1%,4.7%~3.2% and 59.5%~2.1% respectively. |
