Abstract:
10 Malus sieversii natural population from Xinjiang，Yili were aimed as research object，the genetic diversity of leaf traits were analyzed.The results showed that,there were abundant variations of M.sieversii leaf traits among/within populations.The CV of M.sieversii leaf length/leaf width (L1/A1) was 11.99%，which was the most stable of all the traits.The maximum CV population was the XY1 population (17.18％)，while the minimum CV one was XY2 population (14.09％).The average value of the broad heritability was 0.8877 within population individuals；but the average value of the broad heritability was 0.7536 among populations，0.3022 for the leaf length/petiole length (L1/L2) and 0.5800 forthe petiole length (L2) which were smaller between the populations. It showed that these two traits among populations performance were unstable and vulnerable to the environment.10 groups were divided into 4 types according to the clustering of leaf shape index that conformity with the terrain. All showed that leaf shape were greatly influenced by the environment. Principal component analysis showed that the former three of the biggest contribution rate were tip angle(α)，leaf base angle(γ)，leaf length(L1),which showed these parameters play an important role in Xinjiang wild apple phenotype classification and be the important indicator in phenotypic analysis of Malus sieversii.
