Experiment was carried out at Regional Agricultural Research Station, Karjat, Raigad, Maharashtra, India during Kharif 2022 for standardization of Field Rapid Generation Advancement (FRGA) technology in Konkan region for rice. The experiment was laid out in Factorial Randomized Block Desing (FRBD) with three replications. The performances for different planting setups, viz., T₁-dense seed sowing in the protected field, T₂-seedling transplanted in close spacing (5 X 5 cm), T₃-seed sowing in protrays and putting in puddled field after 15 days, T₄-seed sowing in protrays and putting in unpuddled field after 15 days, T₅-seed sowing in protrays and putting in polycarbonate house (no control condition) and T₆-control: normal transplanting at 15 x 20 cm on three genotypes, namely V₁-early (115-120 days)-KJT3, V₂-mid late (125-130 days)-KJT₅ and V₃-late (140-145 days)-KJT2 were evaluated for plant height (cm), days to first flowering, days to premature harvest and immature seed germination count (%) for standardization. It was noted that the significant maximum plant height was measured in T₁-Dense seed sowing in the protected field. The significant highest early days to first flowering and days to premature harvest were achieved in T₄-Seed sowing in protrays and putting in unpuddled field after 15 days planting setup in field RGA was successfully achieved. The significant highest immature seed germination count (%) was achieved in T₃-Seed sowing in protrays and putting in puddled field after 15 days in the field RGA was denoted. This noted outcome provide promising solution for addressing the plant breeding limitation of longer seed to seed generation times. The reduction in generation time provides fast variety release process ultimately increasing genetic gain and contribute to food security in rice.
