Abstract:
With 20 kinds of Baisha Loquat resources of 16-year-old self grafted trees collected from Taihu Technology Promotion Center of Evergreen Fruit Trees of Jiangsu Province as test materials,the genetic variation,character correlation and principal component were studied on 20 kinds of Baisha Loquat resources based on 9 traits.The results showed that abundant variation existed in these traits.The widest variation was found in the number of lateral shoots that had a coefficient of variance of 44.1%,followed by the length of lateral shoots (36.1%),length of petiole (26.7%),length of central shoots (25.0%),thickness of lateral shoots (22.0%),width of petiole (13.1%),width of leaf blade (12.9%),thickness of central shoots (11.9%) and length of leaf blade(10.5%).There were significant correlations among those physiological characteristics.The biggest correlation coefficient between the length of lateral shoots and thickness of lateral shoots was 0.83.Four principle elements were obtained,which contributed over 83.58% of variance,especially the height factor 43.72%.
