<p>Pusa Rice Hybrid 60 (PRH 60) (IET 28965) is a high-yielding, short-duration, long-slender grain aromatic rice hybrid developed at the Division of Genetics, ICAR–Indian Agricultural Research Institute (ICAR-IARI), New Delhi. Developed through a cross between the thermo-sensitive genic male sterile (TGMS) line, Pusa 1S and the aromatic rice genotype, PRR 418, the hybrid represents an advanced two-line hybrid rice technology with simplified seed production compared to conventional three-line systems. Pusa RH 60 matures in approximately 120 days and recorded an average grain yield of 59.24 q/ha across three years of evaluation in Bihar and Uttar Pradesh. The hybrid exhibited an 11.6% yield advantage over the national hybrid check US 314, a 25.3% advantage over the national varietal check CO 51, and a 40.8% superiority over the zonal check in AICRPR trials.
