【中文摘要】 本研究對香菇的平均菇重、菇數(shù)、菇峰期等三個主要數(shù)量性狀與產(chǎn)量的遺傳相關(guān)及通徑系數(shù)進(jìn)行了分析。結(jié)果表明,平均菇重及菇數(shù)與產(chǎn)量呈正相關(guān),且后者與產(chǎn)量的相關(guān)達(dá)極顯著水平,而菇峰期與產(chǎn)量則呈極顯著的負(fù)相關(guān)。三個性狀對產(chǎn)量的決定系數(shù)之和達(dá)96.41％.表明該三個性狀為影響產(chǎn)量的主要因素.

【英文摘要】 The genetic correlations of three important quantitative characteristics to yield in Lentinula edoden were analysed. In addition, their path coefficient analysis was also made in this study. The results indicated that the average weight of fruitbodics and the number of fruitbodies were positively correlated to yield, and the correlation between the number of fruitbodies and yield was highly significant, whereas peak fruiting period was significantly and negatively correlated to yield. While the sum of determinative coefficients of three characteristics was 96.41 %, so these three characteristics were principal factors concerning yield.
