Abstract
Yield interaction of rice genotypes under different environments was found in this study. The experiment of this study was focused on yield adaptation of 14 KDML105 Introgression Lines (ILs) (developed by NSTDA of Thailand) compared with the original KDML105. Fourteen ILs containing different gene combinations of Bacterial Blight Resistance, Blast Resistance, Brown Planthopper resistance and submergence tolerance, were evaluated across three diverse locations of Northeastern Thailand, including Khon Kaen, Nong Khai, and Roi Et (totally 6 environments). The experiment was conducted in 2019 and 2020 during wet season and laid out in a randomized complete block (RCB) design with three replications. Grain yield and natural disease incidence related to traits of improvement were mainly considered in this study. Yield stability analysis indicated that there were four genotypes showing high yield stability including genotype 4 (RGDU03009-11-107-13-B), 6 (RGDU03012-218-19-7-B), 7 (RGDU03014-381-193-1-B), and 8 (RGDU03014-381-197-1-B). While, another four genotypes (1 (RGD00002-MS83-3-B4-49), 10 (RGDU03009-5-46-1-B), 12 (RGDU03028-MS109-MS9-MS4-36-B-B), and 14 (RGDURSC-6-14G08)) showed specific adaptation. Moreover, the results revealed that Bacterial Blight (BB) infection was the main factor affecting yield stability. Among specific adapted genotypes, three BB-resistant ILs, including 1, 12, and 14, were well adapted to severe BB infection environment. Therefore, these three genotypes could provide a new improved rice varieties for BB resistance in Northeastern Thailand. Additionally, these results suggest that BB resistance is a prerequisite for future rice breeding in northeastern Thailand. |
