在四川省达州市野外青杠树林采集到一株健壮侧耳(Pleurotus)子实体,经分离纯化及多年筛选后确定一个优良菌株“达平1号”(E15)。再以本地主栽品种“金2-1”(E59)、“杂优3号”(E60)为对照的比较试验中,2014年春秋两次区域试验表明:E15比对照品种E60增产8.8%,2014~2015年生产试验中比对照品种E60增产9.7%;E15菌丝生长速度、出菇温度范围等均高于对照品种。遗传差异分析表明,E15与E60遗传相似性达95.7%。E15是一个综合性状较为优良的美味侧耳(P.sapidus)新品种。
A robust fruiting body of Pleurotus was collected from the green trees in Dazhou, Sichuan Province. After isolation, purification and selection for many years, an excellent strain “Daping No.1” (E15) was identified. In comparison with the local cultivars “Jin 2-1” (E59) and “Eutai No.3” (E60), two regional trials in spring and autumn in 2014 showed that E15 was higher than that of the control E60 The yield was increased by 8.7%, and the yield increased by 9.7% in the production test from 2014 to 2015 compared with the control cultivar E60. The growth rate and fruiting temperature range of the mycelial growth of E15 were higher than those of the control. Genetic analysis showed that the genetic similarity between E15 and E60 was 95.7%. E15 is a new breed of delicious P. sapidus with better comprehensive characters.
