Abstract: The Design of worldwide rice production is linked to the development of hybrid rice. Total rice growing land will be reduced due to the production of hybrid rice which has helped to feed people worldwide. The present study was initiated to select the few hybrid seeds of rice as compared with Nationally selected 6 number of check hybrid seeds or control. The field experiment was conducted at Nuziveedu Seeds Limited, Regional Research Station, Barrackpore, 24 Parganas North (22º 7’48” and 88º 30’ 0’’ E), Kolkata-700121, West Bengal, India, during the Rabi season in the year of 2021-2022. Altogether, sixty-six (66) treatments were carried out in a Randomised Complete Block Design (RCBD) with four replications in the Regional Research Station. The obtained data exhibited the higher yielding capacity only 12 No. of hybrids and the occurrence of a 5% extra yield deviation from the control hybrids' yielding capacity. The tallest height (cm) of variety (T58= NPHK-2), maximum length (cm) of panicle (T40=TCH-54), highest Days of Flowering (50%) (T57=NPHK-14 and T27=NPHK-3), highest of Ear Bearing Tiller number (T13=NPHK-28), highest Grain panicle-1 number (T51=TCH-44)), maximum Chaffs panicle-1 number (T19=TCH-100), highest Plant yield (gm) (T54=TCH-94), maximum 1000 Grain weight (gm) (T49=TCH-97), maximum Plot yield (Kg) (T49=TCH-97) and maximum Yield production tons ha-1 (T49=TCH-97) were observed all morphological parameters in compares with control treatments. Out of the 60 hybrids, only 12 numbers promising hybrids T49= TCH-97, T50= NPHK-17, T51= TCH-44, T52= NPHK-18, T53=TCH-38, T54=TCH-94, T55=TCH-106, T56=TCH-42, T57=NPHK-14, T58= NPHK-2, T59= NPHK-8, and T60=TCH-86 in yielding capacity have been selected for large scale seed production. Henceforth, the above-mentioned hybrid seeds are available for undertaking large-scale farming by farmers.
