Agronomic and yield selection of doubled haploid lines of rainfed lowland rice in advanced yield trials

Abstract. Akbar MR, Purwoko BS, Dewi IS, Suwarno WB, Sugiyanta, Anshori MF. 2021. Agronomic and yield selection of doubled haploid lines rainfed lowland rice in advanced trials. Biodiversitas 22: 3006-3012. Selection process is important step to obtain high yielding variety. This study aimed information on agronomic performance trials select the best for multi-location Two experiments were conducted Bogor Subang using a randomized complete block design each location consisted 35 two check varieties namely Ciherang Inpari 18 as treatment. The result revealed that interaction between genotype environment (G x E) significantly affected all characters, except panicle length. Characters with heritability value characters number productive tillers productivity. Genotypic correlation analysis showed weight 1000 grains had significant positive used weighted index based multivariate analysis. Fourteen selected These characteristics follows: (14.0-17.7 tillers), (24.7-32.5 g), productivity (5.0-6.2 ton ha-1). can be evaluated further superior
