三个金针菇新品种的选育报告

The new Flammulina filiformis cultivar ‘Shangyan 52’ was bred by multi-spore inbreeding using the strain ‘Shangyan 1’ as parent. The basidiospores of the parent strains were mutated by normal atmospheric pressure and room temperature plasma mutagenesis. The fruiting body of ‘Shangyan 52’ is white, with numerous buds; the pileus is buckled and hemispheric, and the stipe is long. The new cultivar ‘Shangyan 76’ was bred by multi-spore inbreeding using the strain ‘T011’ as parent. The basidiospores of the parent strains were also mutated by normal atmospheric pressure and room temperature plasma mutagenesis. The fruiting body of ‘Shangyan 76’ is white; the pileus is small, thick, buckled and hemispheric, and the stipe is short and thin. The new cultivar ‘Shangyan 84’ was bred by single spore crossbreeding using the strains ‘Shangyan 1’ and ‘T011’ as parents. The fruiting body of ‘Shangyan 84’ is white, with numerous buds; the pileus is large, buckled and hemispheric, and the stipe is thick. There is no significant difference in the growth period of ‘Shangyan 52’ and ‘Shangyan 84’ and the main cultivar, and the growth period of ‘Shangyan 76’ is 2-3 days longer than that of the main cultivar.
