Breeding and cultural characteristics of a newly bred Lentinula edodes strain, 'Bambithyang'

Abstract

A new cultivar, ‘Bambithyang’, was bred from monokaryotic strains of Sanbaekhyang and SANJO 707ho using the mono-mono hybridization method. Its incubation period was determined to be 100 days and its optimum temperature for fruit body flushing, 11-20°C. The mushrooms had a convex cap (diameter, 69.6 mm; thickness, 15.2 mm) and stipes in their center. The color of their upper sides was chestnut brown; their gills were arranged in a ripple style and had medium density. Their scales were cream-colored and fully distributed; the stipes were cream-colored and cylindrical (thick upper part). They also had cream colored fluffs and sporadic fruiting bodies. Zone lines were present when they were cultivated with mother and father varieties. Their stipe lengths and caps were 9% shorter and 16.9% thicker, respectively, than those of Sanbaekhyang.
