Evaluation of recombinant inbred lines for low soil phosphorous tolerance derived from Rasi - a low soil phosphorous tolerant variety
Rasi is a P efficient genotype identified by ICAR-IIRR, Hyderabad, lacking Pup1, the known major low soil P tolerance QTL-. In the present study, a set of 214 recombinant inbred lines (RILs) developed from cross Rasi x Improved Samba Mahsuri was evaluated in a low soil P plot (available P < 2 k...

| description | Rasi is a P efficient genotype identified by ICAR-IIRR, Hyderabad, lacking Pup1, the known major low soil P tolerance
QTL-. In the present study, a set of 214 recombinant inbred lines (RILs) developed from cross Rasi x Improved Samba
Mahsuri was evaluated in a low soil P plot (available P < 2 kg ha-1) and normal soil P plot (available P >18 kg ha-1) at
ICAR- IIRR along with known tolerant and the sensitive checks. The RILs showed high genetic variability for the traits
associated with low soil P tolerance. Stress indices were calculated based on the yield and the RILs were grouped into
highly tolerant, tolerant and sensitive lines. Thirty-six RILs performing better than the tolerant checks and exhibiting
excellent tolerance to low P and a yield reduction of < 40% were identified. These RILs can serve as donors for the
new novel source for low soil P tolerance. |
