A series of pretreatments steps were employed, including husk removal and a 30-hour seed moisture conditioning period, followed by EMS mutagenesis treatments at different concentrations and durations, and a post-treatment involving exogenous gibberellin application. An M2 mutant population was constructed. Agronomic traits were investigated at the milk stage to evaluate the mutagenic effects and to screen the high-yielding germplasm. The results indicated that soaking seeds in 98% concentrated sulfuric acid for 6 minutes effectively removed the husk barrier of forage oat seeds. Adjusting seed moisture content to 50% via a 4-hour soaking facilitated efficient penetration of EMS into the seed. The optimal EMS mutagenesis conditions for forage oat were determined to be 1.0% EMS treatment for 16 hours. Treatment of mutagenized seeds with 50 mg·L-1 exogenous gibberellin significantly improved seedling growth. Compared with the control without added gibberellin, the germination rate increased by 8.5%, and the seedling length also recovered to the level of the non-mutagenized seedlings. This EMS mutagenesis technique systematically addressed key limiting factors in forage oat, including seed permeability barriers, inconsistent physiological states, and mutagen-induced damage. In the M2 generation, the mutagenic efficiency for obtaining high-yield potential germplasm reached 1.92%, and 13 elite high-yield potential germplasms were successfully identified., authors=ZHONG Zhi-hua1, LU Mao-jin1, WANG Rong1, YANG Guo-dong1, LIU Chao1, MA Xiang2, YAN Ming-ke1, WANG Ya-fang1, GUO Huan1, authorsList=ZHONG Zhi-hua, LU Mao-jin, WANG Rong, YANG Guo-dong, LIU Chao, MA Xiang, YAN Ming-ke, WANG Ya-fang, GUO Huan, authorCompany=1 College of Grassland Agriculture, Northwest A&F University, Yangling, Shaanxi Province 712100, China;

本研究以‘中天4号’饲用燕麦(Avena sativa L.)种子为材料,通过去除稃皮和连续30 h种子含水量调节的前处理,不同浓度和时间的EMS诱变处理,以及赤霉素外源施加的后处理,优化饲用燕麦EMS诱变技术体系。构建M₂代突变群体,于乳熟期调查其农艺性状,评估诱变效率并筛选高产种质。结果表明:98%浓硫酸浸泡6 min可有效去除饲用燕麦稃皮障碍,调节种子含水量至50%(4 h浸泡)可促进EMS高效地进入种子,筛选出饲用燕麦EMS最佳诱变条件为1.0% EMS处理16 h,采用50 mg·L⁻¹外源赤霉素处理诱变种子可显著促进诱变后幼苗生长(P<0.05),与未添加赤霉素的对照相比,发芽率显著提高8.5%,苗长也恢复至未诱变幼苗水平。该EMS诱变技术系统性地克服了饲用燕麦种子渗透障碍、生理状态不一及诱变损伤等关键限制因素。M₂代获得高产潜力种质的诱变效率达到1.92%,筛选到13份表现优异的高产潜力种质。

In this study, the forage oat (Avena sativa L.) cultivar ‘Zhongtian No. 4’ was used as the experimental material to establish an optimized ethyl methanesulfonate (EMS) mutagenesis system. A series of pretreatments steps were employed, including husk removal and a 30-hour seed moisture conditioning period, followed by EMS mutagenesis treatments at different concentrations and durations, and a post-treatment involving exogenous gibberellin application. An M2 mutant population was constructed. Agronomic traits were investigated at the milk stage to evaluate the mutagenic effects and to screen the high-yielding germplasm. The results indicated that soaking seeds in 98% concentrated sulfuric acid for 6 minutes effectively removed the husk barrier of forage oat seeds. Adjusting seed moisture content to 50% via a 4-hour soaking facilitated efficient penetration of EMS into the seed. The optimal EMS mutagenesis conditions for forage oat were determined to be 1.0% EMS treatment for 16 hours. Treatment of mutagenized seeds with 50 mg·L-1 exogenous gibberellin significantly improved seedling growth. Compared with the control without added gibberellin, the germination rate increased by 8.5%, and the seedling length also recovered to the level of the non-mutagenized seedlings. This EMS mutagenesis technique systematically addressed key limiting factors in forage oat, including seed permeability barriers, inconsistent physiological states, and mutagen-induced damage. In the M2 generation, the mutagenic efficiency for obtaining high-yield potential germplasm reached 1.92%, and 13 elite high-yield potential germplasms were successfully identified.
