航天诱变丝球小奥德蘑获得优良菌株
Space induced Oudemansiella apalosarca to obtain excellent strain
摘要
Abstract
Oudemansiella apalosarca,a rare edible fungus with high nutritional value,faces the issue of poor uniformity in fruiting body stipes,necessitating strain improvement.In this study,space mutation breeding technology was employed to induce mutations in the mycelium of O.apalosarca strains,with a non-mutated strain serving as the control(CK).Con-tinuous subculture tests,fruiting tests,mycelium evaluation,and agronomic trait assessment were conducted to analyze the mutation direction,stability,and fruiting performance of the mutant strains during subculturing.The results indicated that six aerospace mutant strains(HK)demonstrated stable antagonistic variation against CK,with growth differences di-minishing with increased subculturing.Agronomic traits of six stable mutant HK strains were assessed,revealing that the space mutation strain HK26 exhibited stable antagonistic variation,a 46.50％higher biological efficiency than CK,re-duced fruiting time by 5 days,and improved uniformity of fruiting body stipes,making it suitable for industrial produc-tion.In conclusion,through the combination of space mutation breeding technology and agronomic trait evaluation,the excellent strain HK26 with high yield and good stipe uniformity was successfully selected.This method presents an effec-tive approach for breeding and advancing the industrial application of O.apalosarca.关键词
