Abstract

Two advanced lines: BR8693-8-4-2-1 and BR8693-17-6-2-2, along with BRRI Dhan49 (S. Ck) and BRRI Dhan33 (R. Ck) as checks were tested at farmers’ field in eight locations such as West Byde (BRRI Gazipur), Khulna (Dumuria), Habiganj (Sadar), Chapainawabganj (Gomostapur), Rangpur (Sadar), Feni (Dagonbhuyan), Chattagram (Hathazari) and Barishal (Sadar) during the season of  Transplanting Aman 2018. The trial was replicated three times in each location. The unit plot size was 17.94 m2 (4.6m x 3.9m). Seeding emergence for eight locations varied from 11-17 July 2018. Seedling age varied from 25-30 days among the locations. Seedlings were transplanted at 20 cm x 15 cm spacing. NPKS and Zn fertilizers were applied at the rate of 0, 15, 50, 12 and 3.6 kg ha-1, respectively. All fertilizers except urea were applied as basal whereas, urea was applied in 3 equal splits at 10, 25 and 40 days after transplanting (DAT) Other standard management practices were followed as and when necessary. No insecticide was used because the two advanced lines were insect resistant and diseases were not controlled (to identify susceptibility and tolerance level of lines). Date of seeding, transplanting, flowering and maturity, lodging tolerance, pest and disease incidence, phenotypic acceptance at vegetative and ripening stage, yield and yield components were recorded. Among the two advanced lines, BR8693-8-4-2-1 line was statistically significant from BR8693-17-6-2-2, BRRI Dhan49 and BRRI Dhan33 respectively and the disease reaction, farmers’ opinion, and special character of insect resistant, BR8693-8-4-2-1 was found to be superior for further variety trial. The main purpose of the experiment is to recommended insect resistant rice genotype for proposed variety trail. For yield estimation, 9 m2 sample area from each plot was harvested at maturity and grain yields were adjusted to 14% moisture content.
