We evaluated 46 rice genotypes in water sufficient non-stress and water-deficit stress conditions during Ahu season of 2018 in PVC pipes. Evaluation of the 6-parent diallel crosses was carried out during Ahu 2019 in plastic tubs. The phenotypic evaluation revealed significant variation for all the characters. Leaf rolling (LR) and drought recovery (DR) had a significant correlation with root traits only, positive with root length and negative with root dry matter and root-shoot ratio. Based on the lowest average LR plus DR score of unity, Basantabahar, Haru Bengunigootia, Lewly, Basmoti Red, Banglami, Ikhojoi, Dimrou, Lachit, Disang and Inglongkiri possessed tolerance to drought stress (7-8% soil moisture content) both at vegetative stage up to 3 weeks |
