Phenotypic performance of F3 progenies from crossbreeding of Sigupai and IRBB27

Abstract Sigupai is one of Aceh’s indigenous rice varieties originating from the Southwestern region Aceh. This variety has advantages in form fluffier and good cooking performance fragrant aroma, easy maintenance, minimal fertilizer requirements. agronomic characteristics that need to be improved such as a harvesting age up six months with high plant stature makes it fall. A series breeding processes analyses have been conducted improve this by crossing IRBB27. The phenotypic characters F3 progenies (genotypes T11, T22, T25) were carried out. purpose study was identify character belonging T25 ). These genotypes originated selected F2 crossbreed between research out at Experimental Farm Genetics Plant Breeding Laboratory, Faculty Agriculture, Syiah Kuala University, Darussalam Banda Aceh, December 2021 June 2022. planting medium used mixture soil manure ratio 2:1. seeds planted consisted (genotype T25, well their parents Sigupai, results showed there 3 plants Sg/IRBB27 prospective developed. genotype T11 (plant no. 6), T22 2). ages ranging 122-132 DAS, shorter heights compared mother parent ‘Sigupai’ (121-127 cm), products 5.13-7.40 tons ha −1 .
