GROWTH, DEVELOPMENT, YIELD, AND QUALITY OF SOME NEW RICE VARIETIES IN QUANG BINH PROVINCE

Abstract

This research was conducted to evaluate the growth, development and yield of some new rice varieties in order to serve quality rice production in Quang Binh province. The nine rice varieties were designed in randomized complete block (RCBD), three replicates for each variety. The research targets were implemented in according to the rice research regulation. The growing time of these varieties were suitable with the local conditions (115-125 days in the Winter Spring and 105-113 days in the Summer Autumn crops). In general, the rice varieties were less susceptible of deseases and had good quality rice, long grain and suitable for the consumer tastes. We selected two varieties, GM2-17 and LL.HH3 (hybrid rice) had high yields in two Winter Spring and Summer Autumn crops, 62.33 quintals/ ha; 60.79 quintals/ hectare (GM2-17) and 70.04 quintal/ hectare; 66.48 quintals/ hectare (LL.HH3), respectively.
