Somatic cell culture at IRRI
Screening techniques for selecting salt- and aluminum-tolerant lines were developed. Selected cells from seed-derived callus culture showed higher relative growth in the presence of Na/Cl. Of 522 entries screened at seedling stage, 6 per cent were tolerant, 14 per cent moderately tolerant, and 80 per cent susceptible. R2 plants of Taichung 65 were tested for aluminum toxicity tolerance. The plants showed a wide range of variation, the number of variants increasing with the duration of callus culture. Variations in both visual and agronomic traits were found in field-grown plants
