Performance of the agronomic traits of six advanced promising lines of red rice (oryza sativa l.) grown on the paddy field

Abstract

Rice in Indonesia is still the main staple food, and every year the demand has increased. Indonesian governments have policies to reach self-sufficiency. The strategic programs to increase rice production were through breeding programs. The research was conducted on paddy fields in the village of Ranomeeto District of South Konawe. The study was carried out from October 2018 to April 2019. This study aimed to determine the differences in the agronomic traits in the aspect of vegetative and generative character from some new types of advanced red rice promising lines grown on the paddy field. The experiment was laid out based on Randomized Complete Block Design (RCBD), which consisted of six red rice lines (GS12-1, GS12-2, GS44-1, GS44-2, GS16-1, GS16-2) and one check variety (trisakti). Each treatment was repeated four times, so there were 28 experimental units. Parameters observed were plant height, leaf number, leaf area, number of tillers, panicle length, total grain number, 1000-grain weight, filled grain percentage, unfilled grain percentage and dry weight per m2 The results showed that there were differences in the agronomic traits of the promising rice lines GS12-1, GS12-2, GS44-1, GS44-2, GS16-1, GS16-2, and trisakti variety on paddy field. The new type of advanced red rice promising lines can well be adapted on paddy fields obtained in GS16-1 lines, followed GS16-2 lines and GS44-2 lines.
