May 1985, I Zijin Town, Gucheng Ziyazakou Village, 800 meters above sea level oak stump, picking a black fungus diameter of 16 cm, a total of fresh weight 350 grams a total of 68, through the fruiting body of the middle layer Tissue was separated to obtain the mother, number 8506. First, the characteristics and characteristics (A) characteristics of the ear: ears for the disc-shaped ears (each ear can generally grow more than 6 ears, an average of 1.8 grams per bundle), accounting for 45 to 60% Single ear accounted for 40 to 55% (average weight of 0.7 grams per tablet). Production tests show that the higher the proportion of the disc-shaped ears, the higher the yield.
