【中文摘要】 本文選用10個平菇菌種單孢分離菌株,進行了多菌種、二菌種和菌種內三組4×4不完全雙列雜交,采用試管平面培養(yǎng)基測定菌絲生長速度。結果表明,菌株間菌絲生長速度差異極顯著,試管平面培養(yǎng)基測定菌絲生長速度誤差小;親本單孢菌株與后代雜交菌株菌絲生長速度間不相關;一般配合力、特殊配合力差異均顯著,菌種間雜交非加性效應占優(yōu)勢,菌種內交配以加性效應為主。本研究共選出菌絲生長速度配合力高的單孢菌株4個,雜交組合5個。

【英文摘要】 Monokaryons isolated from 10 strains of oyster mushroom were selected to cross according to 4 x 4 incomplete diallel in multi - strain, two - strain and intra - strain groups in this paper. Strains were cultured in flat medium of test- tubes and mycelial growth rate was measured. The result showed that the variances of mycelial growth rate among strains were most significant and the error of the growth rate of mycelium cultured in flat medium of test - tubes was small. And it was concluded that the mycelial growth rate between parental monokaryons and hybrid dikaryons was uncorrelated, that the variance of general combination ability and special combination ability was significant, and that the non - additive effect was dominant with inter - strain crossing and the additive effect played main roles with intra - strain crossing. While 4 monokaryons and 5 hybrid dikaryons with high combination ability of mycelial growth rate were selected.
