不同紫云英品种物候期及主要经济性状研究

Research on phenophase and main economic character of different Astragalus sinicus varieties

在福建省对15个紫云英Astragalus sinicus品种(系)生长生育过程的特征和特性进行研究,结果表明:所选育并正在扩繁的8个品种(系)8410441、8324411、84471031、8428121、84341022、8487711、闽紫6号和8454311表现中熟,生长性状表现良好,各项指标优于从外省引进的品种,特别是盛花期鲜草产量都比引进种常德种有显著的提高,说明这8个品种(系)可以进行大规模扩繁鉴定,为紫云英育种提供优良材料。

Study on phenophase and main economic character of 15 strains of Astragalus sinicus in Fujlan indicated that 8 strains were mld-maturlng with good growth traits, and better than varieties from out of province in investigated indexes. These strains were 8410441,8324411,84471031,8428121, 84341022,8487711,8454311 and Mingzi 6. Their forage yields were higher than Chang＇de variety（introduced uariety） at full flowering stage. They would to be new varieties or good materials for breeding in further after verifying and large amount of seeds were produced.
