New Method of Selecting Auricularia auricula Strains Suitable for the Corncob Cultivation

Objective:To obtain a simple and rapid Auricularia auricula selection method that is suitable for the corncob cultivation.Method:The plate cuture method using the medium containing the pure corncob and agar was used to select Auricularia auricula strains that was suitable for the corncob cultivation.Result:Two Auricularia auricula strains(strain HW10 and HEI 29) were selected to be suitable for the corncob cultivation from the test 20 strains in 20 days.Comparing the corncob cutivation with the sawdust cutivation,the economic character of the Auricularia auricula fruiting body was not different.For strian HW10,the yield of Auricularia auricula was up to the highest when the content of the corncob was 40%,and the yield increased by 7.25% comparing with the sawdust cutivation.For strain HEI 29,the yield of Auricularia auricula was up to the highest when the content of the corncob was 30%,and the yield increased by 8.82% comparing with the sawdust cutivation.Conclusion:The results showed the plate cuture method was suitable for selecting Auricularia auricula strains with the corncob cultivation because it was easy to operate,could shortern the selection time and decrease the cost.
