Breeding and character evaluation of Astragalus sinicus New line Minzi 8
摘要
Abstract
[Objective]In response to the demand for high-quality leguminous forage and green manure in the southern region of China,particularly Fujian Province,breeding of new variety Astragalus sinicus,with characteristics of mid-maturity,high fresh grass yield,rich nutritional value,and broad adaptability,was necessary.[Method]Using Wanzi 9-70-3 as the female parent and Zhezi 5-12 as the male parent,systematic hybrid breeding was conducted,followed by multi-year,multi-location comparative trials,regional trials,and production trials.[Result]A new Astragalus sinicus line Minzi 8 was successfully bred,characterized by its high quality,high yield,and dual utility as both forage and green manure.Multi-year comparative trials in Fujian Province demonstrated that Minzi 8 has an average growth period of 210 days(ranging from 201 to 216 days),with an average fresh grass yield of 52189.9 kg·hm-1,dry grass yield of 8699.2 kg·hm-1,and seed yield of 634.4 kg·hm-1.Compared to the control variety Shengzhong,Minzi 8 showed increases of 12.9%-16.9%in fresh grass yield,9.2%-16.6%in dry grass yield,and 5.6%-8.3%in seed yield.When compared to the control variety Minzi 7,it exhibited increases of 10.6%-16.7%in fresh grass yield,8.4%-17.3%in dry grass yield,and 6.0%-7.3%in seed yield.In 2021 to 2022,Minzi 8 participated in the national grass variety regional trials.The dry grass yield of Minzi 8 was significantly higher than that of the control varieties Minzi 7 and Shenzhong Chinese milk vetch in all four trial areas and six annual points.In 2023,Minzi 8 passed the national grass variety certification(National S-BV-AS-003-2023)and was also certified as a green manure variety in Fujian Province(Fujian Certification Fertilizer 2023001).[Conclusion]The new variety Minzi 8 can be used as an excellent leguminous forage variety in the southern region of China and can also be used in short-term rotations in traditional farming areas or green manure crop varieties in orchards and tea plantations.关键词
