Genetic analysis of heat tolerance at anthesis in rice por Jagadish, S.V.K., Cairns, J., Lafitte, R., Wheeler, T.R., Price, A.H., Craufurd, P.Q.

“…An F6 population of 181 recombinant inbred lines of Bala (tolerant) × Azucena (susceptible) was screened for heat tolerance at anthesis by measuring spikelet fertility at 30°C (control) and 38°C (high temperature) in experiments conducted in the Philippines and the United Kingdom. The parents varied significantly for absolute spikelet fertility under control (79–87%) and at high temperature (2.9–47.1%), and for relative spikelet fertility (high temperature/control) at high temperature (3.7–54.9%). …”

Epicuticular Wax and Cuticular Resistance in Rice por O'Toole, J.C., Cruz, R.T., SEIBER, J.N.

“…The porometry and GLC techniques may be useful in selecting parents, spot checking in a pedigree program, or checking lines reaching the yield testing stage, but ate not well suited lor mass screening early generation progeny.Significant differences were found in the two rice cultivurs, ‘63–83′, an upland adapted rice from West Africa, and “IR20′, bred and selected in submerged paddy culture in ihc Philippines, by tlie above methods of characterizing cuticular resistance and epicuticular wax. …”

Hydraulic properties of rice and the response of gas exchange to water stress por Stiller, Volker, Lafitte, H. Renee, Sperry, John S.

“…We investigated the role of xylem cavitation, plant hydraulic conductance, and root pressure in the response of rice (Oryza sativa) gas exchange to water stress. In the field (Philippines), the percentage loss of xylem conductivity (PLC) from cavitation exceeded 60% in leaves even in watered controls. …”

Improved Semidwarf Rice Lines with Tolerance to Submergence of Seedlings por Mackill, D.J., Amante, M.M., Vergara, B.S., Sarkarung, S.

“…Experimental lines combining short to intermediate stature (80–115 cm) with tolerance to submergence were developed from tall, lowyielding tolerant cultivars at the International Rice Research Institute Los Baňos, Philippines. Lines were selected based on high survival after submergence in concrete tanks and visual evaluation of yield potential in the field. …”
