Abstract: During rabi season of 2021-2022, a field experiment was undertaken at the District Seed Farm, Bidhan Chandra Krishi Viswavidyalaya, West Bengal, India. The experiment employed a Randomized Complete Block Design (RCBD) comprising seven treatments, each representing a different variety of Indian Mustard (Pusa Mustard 25, Pusa Mustard 26, Pusa Mustard 27, Pusa Mustard 28, Pusa Mustard 30, Pusa Mustard 31, and Pusa Vijay), with three replications. The experimental results unveiled significant differences among the varieties regarding phenology, yield-attributing characteristics and yield. Regarding phenology, it was observed that the duration required for flower initiation, 50% flowering, 100% flowering and maturity were the longest in Pusa Mustard 28, recording as 48 days, 56 days, 65 days and 109 days, respectively. Pusa Mustard 28 also showed the highest number of branches and siliqua per plant. Furthermore, Pusa Vijay produced the heaviest seeds, with a 1000-seed weight of 4.26 grams. Pusa Mustard 31 exhibited the highest number of seeds per siliqua (16.3), while Pusa Mustard 25 produced the longest siliqua with an average of 6.35 cm. With superior yield-attributing characteristics, Pusa Mustard 28 achieved the highest seed yield (1409 kg ha-1). In the evaluation of phenology, yield and yield-attributing characteristics, Pusa Mustard 28 and Pusa Mustard 31 demonstrated notably superior performance among all the varieties.
