Abstract

In two crop seasons of 2018, Winter-Spring and Summer-Autumn, in Long An, Can Tho, Hau Giang, An Giang and Tra Vinh provinces, an assessment of stability and adapability of heat-tolerant rice lines (HTL) was conducted. The experiment was performed as a randomized complete block design (RCBD) with 3 replicates. The quantity of fertilizers was equally applied for all treatments, including 100 kg N, 40 P2O5 and 30 kg K2O/ha. The results showed that HTL1, HTL2, HTL5, HTL7, and HTL8 were promising hybrid lines as they had short growth periods and high yields with good heat-tolerance. These rice lines were adapted well to both Winter-Spring and Summer-Autumn crops as indicated by the analysis of rice line and environment interaction.

Keywords: Adaptability, Heat-tolerant rice lines, Stability
