Abstract:

To elucidate the genetic variation rule of seed and fruit morphological traits of Polygonatum Cyrtonema Hua. at the provenance level, and provide a theory foundation for superior provenance selection of Polygonatum Cyrtonema Hua., the difference of the longitudinal, transverse and lateral diameter of fruit, the longitudinal, transverse and lateral diameter of seed, single fruit weight and 1000-grain weight of seed among different provenances of Polygonatum Cyrtonema Hua. was compared by using 18 provenances as materials which were cultivated in the common garden experiment in Changsha. The results showed that: all the morphological traits of seed and fruit of Polygonatum Cyrtonema Hua. with different provenances reached highly significant difference. There was a highly significant positive correlation of fruit traits, and so was that of seed traits. However, fruit traits and seed traits only had weak correlation. The different provenances of Polygonatum Cyrtonema Hua. showed no obvious geographical variation. The broad sense heritability of seed morphological-traits of Polygonatum Cyrtonema Hua. was in strong genetic range at the provenance level, and they could be inherited stably. It is suggested that the 1000-grain weight can be used as the indirect index to select the superior provenance of Polygonatum Cyrtonema Hua..
