Abstract
The experiment was conducted at the Department of Agronomy, Yezin Agricultural University (YAU), Nay Pyi Taw, Myanmar from September to October 2023. The two experiments control (saturated) and anaerobic germination (flood 10 cm water depth immediately after seeding) were carried out separately and laid out factorial arrangement in randomized complete block design (RCB) with three replications for seed priming treatments: T1= non-priming, T2= hydro-priming, T3= on-farm priming and T4= osmo-priming as factor A and the newly selected AG tolerant upland rice genotypes (Pin To Yin, San Shwe Ni, Kha Lyein Khan-Lawe and Khao Mon Hom Kyae) and two check genotypes Khao Hlan On (tolerant) and Inpara-3 (susceptible) as factor B. The findings of the study indicated that different seed priming methods showed higher survival percent, days of leaf tip reached the flood water surface (DLTRS), shoot and root length, shoot and root dry weight, seedling vigour index (SVI)-I and seedling vigour index (SVI)-II than non-priming. All four newly selected tolerant genotypes showed higher performance in most of the traits than tolerant check in AG condition. The maximum survival percent was observed in Pin To Yin with hydro-priming treatment under control condition and Pin To Yin with osmo-priming treatment under AG condition whereas the minimum survival percent was observed in Inpara-3 with non-priming treatment under both conditions.
