【摘要】 以香菇(Lentinula edodes)5個優(yōu)良栽培菌株為親本,設計3對雜交組合,獲得55個雜交菌株,其中19個雜交菌株出菇正常。采用灰色關聯度分析法,從菌蓋厚度、菌柄直徑、平均單菇重等8個性狀對19個雜交菌株進行綜合評價。在3對雜交組合中,QK-8、QK-15、W-2、W-13和Q6-12等5個雜交菌株的關聯度排名較靠前,農藝性狀和子實體性狀也明顯優(yōu)于親本和其它雜交菌株。

【Abstract】 Monokaryotic basidiospores derived from five parental Lentinula edodes strains (Q6,Wx-1,K95-41,L205 and L605) were mated according to three pairing groups (Group 1,Q6×L605; Group 2,Wx-1×L205; Group 3,Q6×K95-1) to yield a total of 55 hybrid strains. Only 19 hybrids produced normal fruit bodies,and these were evaluated by grey correlation analysis in terms of eight agronomic traits:cap thickness and diameter,stipe diameter and length,average fruit body weight,number of fruit bodies and yield per growth bag,and the period between substrate inoculation and fruiting. Five hybrids (QK-8,QK-15,W-2,W-13 and Q6-12) derived from the three crossing combinations exhibited superior agronomic characteristics that ranked closest to a projected ideal strain.
