Selection of drought-tolerant lines of rice (Oryza sativa L.)
2002
Truong Thi Bich Phuong | Ton Nu Gia Ai | Nguyen Hoang Loc | Nguyen Huu Dong
Using the procedure of stepwise adaptation, we obtained the drought (mannitol)- tolerant callus lines of both rice cultivars, 271 and 212. Stability in callus cultures that have been selected for drought tolerance was demonstrated by survival of the selected calli on return to selective medium after 6 months in the mannitol-free medium. Similarly, four regenerated plant lines from selected calli 271 and two lines from calli 212 still expressed stability of drought tolerance after 6 months in the medium without mannitol
