Abstract:

In order to study the growth performance and production value of Chinese hybrid rice in Cambodia, 13 Chinese hybrid rice varieties were planted in Bakan county of Pursat province, Cambodia in 2016. The results showed that 13 Chinese hybrid rice varieties could grow normally in test plots. The whole growth period was 86~98 d and the total leaf number of main stem was 14~15. With the fully and coordinately supply of water and fertilizer during the growth period, the seedling were transplanted with the 24 cm row spacing and 10cm planting spacing, and the final plant height was 80~105 cm, the elongated internode number was about 5, the panicle rate of the stem tillers ranged from 51% to 76%, the panicle number was 6.9~9.9 per plant. The main panicle length was 22~30 cm, the total grain number per panicle was 161~253 and the filled grain number per panicle was 154~238. The seed setting rate was about 90%. The thousand grain weight was 19.7~30.1 g, the panicle weight was 2.37~4.59 g, the yield was 21.8~37.7 g per plant. In the trial field, the yield of rice was 6.8~10.5 t/hm2.
