  • In this paper,we observed the agronomic traits of the hybrids between Hainan common wild rice（ Oryza rufipogon Griff.） and bar transgenic rice（ abbreviated as F1hybrids） to analysis their adaptability under different water depth. Results showed that the seed vigor of F1 hybrids generally higher than that of common wild rice. When the water depth reached 10 cm,the biomass of wild rice was obviously better than that of F1 hybrids in general,and the biomass both wild rice and F1 hybrids decreased with water depth increasing. In plant height,wild rice was generally higher than that of F1 hybrids,and the water depth had a little impact on their leaf areas. Comparing the growth of weeds between this experiment and the simulating condition of in situ conservation,we found the deep water had an obviously inhibitory effect on weed growth.

Abstract: In this paper,we observed the agronomic traits of the hybrids between Hainan common wild rice（ Oryza rufipogon Griff.） and bar transgenic rice（ abbreviated as F1hybrids） to analysis their adaptability under different water depth. Results showed that the seed vigor of F1 hybrids generally higher than that of common wild rice. When the water depth reached 10 cm,the biomass of wild rice was obviously better than that of F1 hybrids in general,and the biomass both wild rice and F1 hybrids decreased with water depth increasing. In plant height,wild rice was generally higher than that of F1 hybrids,and the water depth had a little impact on their leaf areas. Comparing the growth of weeds between this experiment and the simulating condition of in situ conservation,we found the deep water had an obviously inhibitory effect on weed growth.
