摘 要:對(duì)10年生的31個(gè)泡桐無性系的生長狀況進(jìn)行了分析.結(jié)果表明,不同無性系間性狀表現(xiàn)差異較大,胸徑的遺傳力較高,可以作為選擇的主導(dǎo)性狀,主干材積的潛在改良能力最大.相關(guān)分析表明,多數(shù)性狀間有顯著相關(guān)關(guān)系,在選育時(shí)應(yīng)統(tǒng)籌兼顧.叢枝病發(fā)病程度在無性系間差異顯著.在本試驗(yàn)條件下,生長性狀優(yōu)良、發(fā)病率較低的無性系為8508-2,毛雜等.

AbstractGrowth characters analysis of 31 10-year-old paulownia clones shows that significant differences exist between different clones that the diameter of breast height may act as the dominant character for selection because of its higher genetic ability, and that the stem volume has the greatest potential for improvement. Correlation analysis indicates that many characters are closely correlated and must be considered during selection. The degree of withches -broom are quite different. The clones 8508-2、Mao-za are the best clones concerning growth characters and witches -broom occurrence frequency.
