荷兰栽培的双孢蘑菇,有白色蘑菇和米色蘑菇两种主要类型。白色蘑菇色洁白,菌盖平滑,大多数很致密,菌褶能长久地保持粉红色,制罐后切片,菇肉颜色更好。白色菌株的子实体比米色菌株的小,有利于市场鲜售。然而,米色蘑菇的采收率比白色蘑菇的高,特别适合机器采收。约在1975年,霍尔斯特试验站试图通过杂交育种使白色菌株和米色菌株的优良品质集中于一个菌株中。试验方法在霍尔斯特,我们收集了白色和米色菌株的孢子,不通过显微操作分离单孢子培养物,开始杂交育种。利用仅仅具有单性核的单孢子培养物进行
The Netherlands has cultivated Agaricus bisporus, there are two main types of white mushrooms and beige mushrooms. White mushroom color white, smooth cover, most of the very dense, gill folds can maintain a long pink, cans after slicing, mushroom color better. The white fruiting body than the small beige strains, is conducive to the market fresh. However, the recovery of beige mushrooms is higher than that of white mushrooms and is particularly suitable for machine harvesting. Around 1975, the Holst Test Station attempted to concentrate the good qualities of white and beige strains in one strain by crossbreeding. Test Methods At Holst, we collected spores of white and beige strains, and did not separate the single spore cultures by microscopic procedures to begin crossbreeding. Using a single spore culture with only monophasic nuclei
