Abstract:
In order to screen the excellent strains of
Volvariella volvacea suitable for the industrial cultivation, six new strains of
Volvariella volvacea were introduced from the places such as Fujian, Jiangsu, Hubei, and Guangdong, etc. By taking the local main cultivated strain V9715 as the control group, the mycelial growth of the tested
Volvariella volvacea strains on the culture medium of mother seeds and pedigree seeds was investigated, and then the indexes such as the characters during the growth period, agronomic characters, yield and biological efficiency were determined. The results showed that there were significant differences in the aspects such as the growth period, bacteria film thickness, mushroom color, size and single weight among the seven strains. Among which, Shanghai No.3 showed good commercial characters, with thick bacteria film, not easy to open, storage resistance, dark gray black and large mushroom body, and heavy average single commercial mushroom. The average yield and average biological efficiency were 24.352% higher than that of V9715. V1295 showed the characteristics of fast mycelial growth, early bud and early harvest.
Volvariella volvacea No.3 showed good commercial characters. The mushroom body was dark gray black, larger and oval, and the yield and biological efficiency were higher, which was 17.273% higher than the control group V9715. Based on the indicators such as mycelial growth, commodity characters, and yield, the suitable strain for the industrial cultivation in Zhangzhou was Shanghai No.3.
