Abstract

Observation is one of the stages in the selection to obtain the expected rice lines to be tested at the yield and multi-location testing stage as candidates for breeding rice varieties. The research was carried out at the Tamanbogo Lampung Experimental Garden in the 2021 planting season (MT) using an augmented design with five replications of comparison varieties: Inpago 8. Inpago 12, Inpago 13. Situbagendit, and Situpatenggang. As many as 247 promising breeding rice lines were used as materials in this experiment with their respective advantages. Each line was planted with a 0.9 m x 5 m plot size with a spacing of 30 cm x 15 cm. Fertilizer used is 300 kg/ha NPK + 100 kg/ha Urea. Weeding is done twice, precisely at the time before the next fertilization I and II. The observations include 50% flowering age, harvest age, plant height, tiller quantity, dry-milled grain yield, and resistance to biotic and abiotic stresses. The analysis of variance showed that the genotype significantly affected plant height and productive tiller quantities. High heritability and genetic advances in plant height characters indicate that this character is a selection criterion so that selection can be made to increase these characters. The comparison varieties significantly affected the character of plant height and productive tiller quantities. From this activity, 37 breeding lines were obtained with higher yields than the comparison varieties.

Abstract

[VARIABILITY STUDIES OF UPLAND RICE LINES ON AN ACIDIC SOIL]. Suscessful upland rice breeding program to produce productive and adaptive to acid soil is dependent upon the extent of genetic variability of the breeding materials. Objectives of this study were to estimate the genetic variability, phenotypic and genotypic coeficient of variations, heritability, genetic advance, and correlation of five traits observed from dari 298 upland rice lines and five checks varieties. A field field experiment arranged in an augmented design was conducted at the Tamanbogo Experimental Station in Lampung 1 MT 2019.. The results of the analysis of variance showed that there was diversity among lines, resulting in differences in appearance on plant height, number of productive tillers, and yields. High heritability, genetic advancement, and high correlation on the number of productive tiller indicate that this character is a selection criteria so that selection can be done in an effort to improve these characters
