Agronomic Performance of Premium Quality Advanced Breeding Lines of Indica Rice

Abstract

An experiment was conducted at the Research field in the west byed of Bangladesh Rice Research Institute (BRRI), Gazipur-1701 during the rabi season (December 2023 to May 2024) to assess the advanced breeding lines for yield and other agro morphological traits of select premium quality rice. The experiment was laid out using a Randomized Complete Block Design (RCBD), comprising eight treatments (five advanced breeding lines and three controls) in three replications. The total numbers of plots were 24. All treatments received full of the recommended doses of N, P, K, S & Zn fertilizers. BRRI dhan104, BRRI dhan107 and BINA dhan25 were used as Check varieties. Crops were harvested at 80% physiological maturity, and the data on the growth parameters and grain and straw yields were recorded. Statistical analyses were conducted with the PB Tools v 1.4. (Version 1.4) package. Results indicated that considering the various agronomic parameters of the advanced lines, the treatment T3 = BR10648-12-1-3-4-1 and T4 =Zira (Nachol) yielded significantly higher than other varieties under experimental trial. It possesses a superior quality long and slender grain, an excellent weight of 1000 grains, and a growth duration of 138 days. These advanced lines can be included in the variety development pipeline to release a variety.
