斑玉蕈三个新品种的选育报告

‘Huzhen No.6’ was a new white strain of Hypsizygus marmoreus bred by hybridization from protoplast monokaryon of strain ‘1007’ and spore monokaryon of strain ‘1306’. Simple sequence repeat (SSR) analysis showed that it was distinctive in comparison with the parents. ‘Huzhen No.6’ exhibits high yield and short cultivation cycle, meeting factory production requirements. ‘Huzhen 11’ is a new grey strain of H. marmoreus developed through single-spore self-crossing of parental strain HM22. SSR analysis verified that it had unique genetic profile as compared with the parent. This strain displays uniform morphology, more fruiting and high yield. ‘Huzhen 17’ is a new grey strain of H. marmoreus bred by hybridization from parent HM21 by multiple spore self-cross-breeding. Compared with its parents, ‘Huzhen 17’ showed more fruiting and elongated stipes. These three varieties (‘Huzhen No.6’, ‘Huzhen 11’ and ‘Huzhen 17’) are unambiguously distinguished from commercial cultivars through verification of SSR fingerprinting profiles.
