目前,食用菌辐射育种研究报导甚为罕见,1974年国外介绍了~(60)Co-γ射线对双孢蘑菇孢子发芽的影响情况,1978年报道了用γ—射线辐照V.esculenta和V.diplasia的厚垣孢子液,未获有益结果。我们以辐射处理侧耳孢子诱发遗传变异,杂交选育无孢子侧耳及早熟高产或高温型品系。 At present, there are very few reports on radiation breeding of edible mushrooms. In 1974, the effect of ~ (60) Co-γray on the spore germination of Agaricus bisporus was introduced. In 1978, it was reported that V. esculenta and V Chlamydospore fluid of .diplasia, no beneficial result. We dealt with the genetic variation induced by irradiation with the ear-ear spores, and cultivated the non-spore-ear and early-maturing high-yield or high-temperature-type lines by hybridization.
