Study on Nut Characteristics Variation and Superior Tree Selection of Carya illinoensis

  • Received Date: 2012-08-16
  • In this study, the nut characteristics of sixty-six Carya illinoensis seedlings introduced to Nanjing in the 1950s were investigated. All traits of these varieties, including the fruit weight, kernel rate, oil yield, fruit shape index, nutshell thickness, fruits' transect diameter, fruit width and fruit longitude diameter, showed significant differences and great potential of genetic improvement. There was no relationship among the fruit shape index, fruit weight, kernel rate, oil yield and nutshell thickness of the sixty-six C. illinoensis seedlings. The pecan can be classified and selected based on the fruit index. According to the fruit index classification by standard deviation, four excellent individuals were selected from eleven big fruit index groups by general coordinate evaluation method. The fruit index and fruit weight of four excellent individual increased by 11.90%-17.26% and 2.81%-21.84% compared with the control group, the nutshell thickness decreased by 1.96%-13.73% except one, the fruit kernel increased by 8.01%-24.33%, and the oil content increased by 6.14%-31.14%. Compared with Jiangsu’s native good variety Zhongshan 25, the fruit index increased by 39.26%-45.93%, the fruit weight increased by 7.39%-17.80%(Ⅵ westig is similar with control group), the kernel rate increased by 8.56%-15.44%, the nutshell thickness decreased by 0.97%-14.56%, the average fruit kernel increased by 8.01%-24.33%, and the oil content increased by 6.14%-31.14%. Nine excellent individuals were selected from forty-four middle fruit index groups by general coordinate evaluation method. Generally, their fruit weight and oil yield increased by 12.95%-25.43%, 2.51%-7.68% compared with that of the control group, the nutshell thickness decreased by 4.90%-14.71%, the kernel rate increased by 1.56%-6.35%, the average fruit kernel increased by 8.01%-26.71%, and the oil content increased by 6.14%-31.14%. Compared with Zhongshan 25, the fruit weight increased by 12.36%-24.72%, the fruit index increased by 11.85%-37.77%, the nutshell thickness decreased by 5.83%-15.53%, the kernel rate increased by 4.17%-14.36%, while the oil content remained the similar. The average fruit kernel increased by 10.98%-30.18%, and the oil content increased by 15.35%-33.77%. Three excellent individual were selected from eleven small fruit index groups by general coordinate evaluation method. The oil yield was similar or slightly higher compared with the control group, the fruit weight and kernel rate increased by 17.32%-24.96% and 1.10%-29.30% (except some individuals), the fruit index decreased by 11.33%-17.86%, the average fruit kernel increased by 10.68%-26.11%, and the oil content increased by 6.14%-33.33%. Compared with Zhongshan 25, the fruit index increased by 2.22%-10.37%, the nutshell thickness decreased by 0.97%-6.80%, the fruit weight increased by 13.42%-20.81%, the kernel rate increased by 5.14%-37.33%, and the oil content and average fruit kernel increased by 13.72%-29.57% and 6.14%-33.33%. The selected excellent individuals can be used in the grafting propagation, clone test and variety breeding.
