Evaluation of tungro-resistant lines based on tungro disease severity and agronomic characteristics

Tungro disease severity and agronomic characteristics of tungro-resistant lines. is one the diseases problem in rice production. The simplest approach to solve use resistance tungro variety, which made At present, character new type becomes a preference by formation variety. line with Agronomy decisive factor choice variety farmers. aim this study was evaluate potential resistant lines according agronomy. research carried out dry season 2015 Polewali Mandar, West Sulawesi. Fifty promising four reference varieties were tested using Augmented Design five blocks as replicates. Variables observed green leafhopper population density presence disease. Agronomic variables included clump shape, productive tiller at 90 DAT, flowering age 50%, weight 1000 grains, filled unfilled grain, grain yield kg/ha. results showed that there several had significantly higher , i.e. BP3734A-3-15-LRG-5-8-2-5, BP3770A-1-218-LRG-2-3-1-9, BP3840A-6-253-LRG-8-6-2-8, BP3862A-21-1054-LRG-5-1-1-6, BP3866A-4-1207-LRG-9-3-2-7, BP3870A-4-1357-LRG-2-3-1-7 BP3870A-4-1363-LRG-8-1-1-7. All these have be processed next phase.
