利用樟子松优树半同胞子代 2 8个家系 3个试点的生长性状 ,进行多点分析 ,结果表明 :家系差异及家系与地点交互作用显著。采用生产力等参数对半同胞家系进行生产力、遗传稳定性和适应性的综合评定 ,为不同地点选出优良家系 13个 ,其中普遍优良的有 4个 ,材积平均增益 37%。分析表明 ,家系生产力、遗传稳定性和适应性三者的关系是多变的 ,选择家系时应慎重 ,既要有面上选择 ,也要有点上选择
Multi-point analysis was conducted on the growth traits of 3 experimental plots in 28 sib families of half-sib son of Pinus sylvestris var. Mongolica. The results showed that there were significant differences in pedigree and family-locus. The productivity, genetic stability and adaptability of semi-sib families were evaluated by productivity and other parameters. Thirteen elite families were selected for different locations, among which four were generally good and the average volume gain was 37%. Analysis shows that the family productivity, genetic stability and adaptability of the relationship between the three is changing, the family should be careful when choosing, it is necessary to have the face of choice, but also a little on the choice
