An experiment was conducted at agronomy field, Sher-e-Bangla Agricultural University (SAU), Sher-e-Bangla Nagar, Dhaka-1207 during the period from November 2017 to May 2018 to evaluate the growth, yield and grain quality of traditional aromatic rice cultivars in Boro season. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Eleven aromatic rice genotypes viz. T1 = Kataribhog-1, T2 = Kataribhog-2 (awned), T3 = BRRI dhan34, T4 = Badshabhog, T5 = BRRI dhan38, T6 = Chinigura, T7 = Madhumala, T8 = BRRI dhan50, T9 = Zirabhog, T10 = Chiniatap-1 and T11= Chiniatap-2. Chinigura produced the tallest plant (151.23 cm), higher number of tillers hill-1 (25.66), and leaves hill-1 (65.00). The maximum leaf area index (5.5) was obtained from Chinigura (T6) which was statistically differed from all other varieties. Days to 50% flowering (92.66 days) was more for Chinigura (T6) which was statistically similar with all varieties except BRRI dhan38 (T5) and Madhumala (T7). BRRI dhan34 (T3) produced the highest chlorophyll content in leaves which was statistically identical with BRRI dhan38 (T5), Chinigura (T6) and Chiniatap-2 (T11). Grain length and breadth ratio is the lowest (2.26: 1) in Kataribhog-1. Chinigura provided the highest grain yield (3.46 t ha-1) followed by Kataribhog-1 (3.32 t ha-1), Badshabhog (3.20 t ha-1), BRRI dhan38 (2.80 t ha-1) and BRRI dhan50 (2.65 t ha-1). Chinigura also provided the highest straw yield (8.11 t ha-1) and biological yield (11.10 t ha-1). So, Chinigura exhibited higher adaptability in Boro season compared to rest of the cultivars. Chinigura can be cultivated in Boro season compared to rest of the cultivars.
