Abstract:
OBJECTIVETo analyze the genetic difference of biological characters on germplasm resources of Sophora alopecuroides.
METHODTwenty-three populations of S. alopecuroides from Ningxia, Gansu, Qinghai, Xinjiang and Inner Mongolian were used to analyze the seed size, 1 000-grain weight, and germination characteristics and so on.
RESULTIt showed that there were significant differences in seed size, 1 000-grain weight and the vitality of seeds. The biggest seed of S. alopecuroides was 4.7 mm x 3.5 mm, and the smallest was 3.8 mm x 2.9 mm, and the 1 000-grain weight was 15-26 g. Results of seeds vitality in 8 populations indicated that the highest vitality of seeds were No. 103 and No. 122. The germination index was 36.51 and 36.24 respectively, and the vitality index was 1 323.49 and 1 274.56. The coefficient of variation in seed traits exceeded 10% except the seed size.
CONCLUSIONThere are some differences and different heredity background in various S. alopecuroides germplasm resources.
