PHENOTYPIC PERFORMANCES AND GENETIC PARAMETERS OF QUANTITATIVE CHARACTERS OF BLACK RICE LINES RESULTED FROM PEDIGREE SELECTION

Abstract

This study aimed to determine phenotypic performance, heritability value, genetic diversity, and genetic advance of black rice lines resulted from Pedigree selection. The field experiment was carried out on an irrigated ricefield in the experimental farm of the Faculty of Agriculture, University of Mataram, located in Nyiurlembang Village, West Lombok, Indonesia, from June to November 2019. The experiment was designed according to Randomized Complete Block Design, with three blocks and 25 treatments consisting of 23 black rice lines (G1 to G23) and two parent varieties, i.e. the white rice variety “Situ Patenggang” (G24) and the black rice variety “Baas Selem” (G25). The results indicated that G1, G2, G8, and G20 were promising lines having high grain yields (7-8 t/ha) with long panicles, large number of filled grains, high weight of 100 grains, and high grain yield per clump. They also showed high values of heritability on days to harvest, plant height, number of productive tillers, panicle length, and number of filled grain per panicle; high values of genetic diversity on number of productive tillers, number of filled and unfilled grains per panicle, and grain yield per clump; and a high value of genetic advance on number of filled grains per panicle.
