Heritability of quantitative characters of local black rice (Oryza sativa L.) results of generation F3

Abstract

Local Black rice is a food crop variety that has a low productivity level and a longer planting time than other colored rice. In addition, black rice contains anthocyanins, which are antioxidant molecules that can counteract free radicals in the human body. Anthocyanin levels can be increased by producing full black potential lines. Effective and efficient selection with heritability analysis. This study aims to determine the heritability of the agronomic character of black rice from the F3 generation line. The study was conducted in the Manipi Sinjai rice field in February – August 2020. The experiment used was a completely randomized design, there were 17 lines with 3 replications. The data obtained were analyzed by means of variance, and if there was a significant effect of treatment, further tests were carried out with the BNT 0.05 test. In addition, the heritability of the observed characters was determined. The results showed that the character of plant height in the flowering phase, days to 50% flowering, and the percentage of grain with full black endosperm had heritability values with high criteria.
