红豆树优良单株子代苗期生长差异分析

对所选择的12个红豆树优良单株进行苗期生长测定,结果表明:优良单株的子代生长效应能明显显示其母本的优良性状特征;其中,优良单株依次为优株4、优株3、优株6、优株8、优株12、优株10、优株2、优株7、优株5,增长率分别为62.1%、34.7%、30.7%、24.2%、20.7%、19.3%、16.9%、8.5%、7.0%.红豆树优良单株子代的地径、苗高、幅度宽度、枝角等性状的广义遗传力分别为8.9%、20.0%、34.9%、13.9%.

Primary Studies on Growth Differences of Filial Generation Seedlings from Superior Individual Trees of Ormosia hosiei

The growth differences of filial generation seedlings from 12 superior individual trees of Ormosia hosiei were compared to study the effects of characteristics of individual trees on filial generation seedlings growth.The results showed that the individual No.4,No.3,No.6,No.8,No.12,No.10,No.2,No.7,and No.5 were primarily identified as superior trees.The growth rate of filial generation seedlings from the individual superior tree above was increased by 62.1%,34.7%,30.7%,24.2%,20.7%,19.3%,16.9%,8.5%,7.0% respectively,compared with the seedlings from control.The average general heritability of ground diameter,seeding height,and crown width of filial generation seedlings from individual superior trees were 8.9%,20.0%,34.9%,and 13.9% respectively.
