Description of maize check genotypes stability for selection on tidal swamp-land for grain production

Abstract

Determination of check genotypes for maize biomass and grain production on the tidal swamp acid soil environment was randomly picked among the genotypes, regarding of the lack information about check genotypes characteristics on tidal swampland. This study aimed to analyze maize check genotype characteristics on a tidal swamp. Five check genotypes (open-pollinated variety=Sukmaraga, hybrid variety=P27, elite lines=NEI9008, elite lines=MR14, three-way cross hybrid=Bima20URI) was planted among 150 maize lines, tested on tidal swampland in three environment treatment (saturated soil culture/SSC, saturated soil culture+temporary flooding/SSC+TF, and acid dry land/DL). Augmented Randomized Complete Block Design (Augmented RCBD) with five replications was used for this experiment. Data were analyzed using PBSTAT-CL 2.1 statistic tool. The result showed that SSC was the most suitable land management technique for maize plant crops in tidal swamp acid soil. Bima20URI grain biomass production was high in SSC land management of tidal swamp environment. Meanwhile, P27 hybrid variety was ideal for all treatments and adaptable to stressed environment. Sukmaraga was unstable genotype on the and declined on SSC+TF but suitable for SSC. NEI9008 genotypes have high productivity in stressed environments, and MR14 line genotype has stable grain production in every treatment environment yet has lower grain productivity.
