Identification of Rice Genotypes Carrying the Pup1 Locus as Potential Donors for Phosphorus Deficiency Tolerance Breeding in Southern India

Kiruba Ganesan & Ramalingam Jegadeesan · International Journal of Plant & Soil Science · 2026

Phosphorus deficiency is a major constraint for rice production. The Pup1 locus confers tolerance to low-P conditions. We screened 40 rice genotypes adapted to southern India using 10 Pup1 specific markers. Five genotypes (including Kasalath and IR64-Pup1 checks) showed the compl...
