Half-sib Progeny Seedling Growth Differences Analysis of the 1.5th Generation Seed Orchard for Castanopsis hystrix
Seeds of 34 half-sib families were collected from 1.5 generation seed orchard of Castanopsis hystrix, all the seedlings were planted in the nursery garden. The plant height, ground diameter, leaf number, chlorophyll relative content (SPAD value), leaf length, leaf width, leaf area were measured and the leaf length-width ratio was calculated. After 15 months growth, the result showed that mean height of each family was 47.2 cm and ground diameter was 5.4 mm. The coefficient of variation in plant height and ground diameter were 25.4％ and 20.7％, respectively. Mean leaf number of each family was 55.3 and mean SPAD value was 38.2. The mean leaf length, mean leaf width and mean leaf area were 9.0 cm, 2.5 cm and 14.3 cm2, respectively. The mean leaf length-width ratio was 3.6. Analysis of Variance indicated that all the eight phenotypes behaved significant differences between families. Based on plant height, ground diameter and coefficient of variation, the four half-sib families A02, A08, A15 and A31 were selected as their excellent performance in seedling stage.
