Abstract

The development of red-kernel rice is prompted by its low glycemic index around 50 which is beneficial for the diabetics. Since 2010 we have been selecting and propagating seeds of red-kernel deviation from five lowland white-kernel rice populations of Lampung local genetic source. The five deviated lines were single-crossed and the seeds were propagated in self to Self-4 generation. The research was to investigate the performances of three prospecting Self-4 inbred lines in an organic upland environment. The research was accomplished in the State Polytechnics of Lampung Research Station from March – July 2016 in a Randomized Complete-Block Design with four replications. Three red-kernel rice inbred lines were tested Megou 1, Megou 2, and Megou 3, namely, and Ciherang variety was used as control. All plots were applied with half-decomposed cow dung of 50 t ha-1. Variables analyzed included plant height, tiller number hill-1, spike number hill-1, grain number spike-1, grain number hill-1, grain dry-weight hill-1, 100-grain weight, and productivity. The results indicated that the adaptation of the three Megou lines in the organic upland environment was better than that of Ciherang as measured on all variables except tiller number hill-1 and 100-grain weight. The genetic variances and broad-sense heritability values among Megou lines for plant height, spike number hill-1, grain number spike-1, grain dry-weight hill-1, 100-grain weight, and productivity were greater than 1x standard error with the values of broad-sense heritability was greater than 60%. The milled-dry grain productivity of Megou 1, 2, and 3 lines achieved 289, 422, and 587 g m-2, respectively, as compared with that of Ciherang 312 g m-2. Keywords: broad-sense heritability, local genetic source, Megou lines, genetic variation, rice breeding, red-kernel rice, upland rice.
