Abstract
The purpose of this study was to applicate fundamental data for breeding new cultivar through selection of superior individuals and to investigate its nut characteristics in walnut hybrids. Selection of superior individuals with good nut qualities including high nut weight (NWT, >13g) and percentage of weight relative to total weight of nut (PWR, >50%) was carried out and then 4 promising individuals ($Sansung 4{\times}Concord-8,\;Concord{\times}Sansungl,\;Concord{\times}Sansung4\;and\;McKinster{\times}Punghan1$) were selected by quantitative characters. Especially width of pad of suture was main factor in selection of nut with high PWR (percentage of weight relative to total weight of nut) In addition, kernel length showed high correlation with kernel and nut weight. Thickness of septem (TOP) also had an effect on ease of kernel removal (EKR). In qualitative characters, there is a great difference among the individuals and cross combinations as well as showed simultaneously various characteristics in the same individual.
