三十二份板蓝根种质材料结籽期主要农艺性状综合评价

Comprehensive Evaluation of Agronomic Trait for Thirty-two Germplasm Materials of Isatis indigotica Fort.at the Seed Bearing Period

板蓝根种质资源是板蓝根研究的重要基础,板蓝根遗传多样性评价有助于种质资源的搜集、管理和利用。为了合理利用板蓝根种质资源,在露地栽培条件下,比较分析了32份板蓝根种质材料在结籽期的物候期和主要农艺性状。结果表明:各种质材料在结籽期的返青期最大极差为21d,展叶期最大极差为22d,现蕾期最大极差为25d,开花期最大极差为27d,结荚期最大极差为17d,株高最大极差为70cm,单株分枝数最大极差为22个,千粒重最大极差为10.21g,单株种子产量最大极差为101.0g。其中种质材料BLG2012-22的种子千粒重最大为14.93g,与其余各品系间自成一类。

Isatis indigotica Fort.germplasm resources were very important for research.Genetic diversity study on Isatis indigotica Fort.was beneficial to the collection,management and utilization of Isatis indigotica Fort.of genetic resources.In order to make efficient use of IsatisindigoticaFort.germplasm resources,the phenophase and main agronomic traits for germplasm and materials of 32 Isatis indigotica Fort.were compared at seed beating period,under the open field cultivation on ditions.The experimental results showed that among the different lines,the widest range of returning green stage could be 22 d,that of the leaf-expansion period could be 22 d,that of the squaring period could be 24 d,that of the blooming period could be 24 d,that of the bearing pod period could be 15 d,that of the number of branches per plant could be 22 poor months,that of the height was 70 cm,that of the grain weight was 10.21 g,that of the seed yield per plant was 101.0g,which the seed weight of BLG2012-22 was the largest of 14.93 g,and the rest of the germplasm between the sui generis.
