Interaksi Genotipe – Lingkungan Galur Harapan Padi Rawa

A study was conducted in 7 location represent to sulfuric-acid, peat or arable land in order to define productivity of several promoting lines of swamp-rice. Foerteen lines with two control varieties were tested in each location. The lines were grown in two different NPK-fertilization, i.e. low and high dosage of NPK. Yhe study was objected to define the genotype-environment or non-specific environment. The result show that the tested-lines adapted to the specific environment, but not to non-specific environment

Most farmers in tidal swamp areas usually grow local varieties with characteristics: adapted to tidal swamp condition, late varieties (9 to 10 month), photoperiod sensitive, very low potential yield (1 -2 ton/ha), specific grain size and accepted taste. Some farmers have grown improved varieties with high yielding ability and early maturity, but not of good adaptability to tidal swamp conditions, grain size and accepted taste. These are the reasons that the improved varieties can not establish on tidal swamp areas. The experiment was conducted on the peaty tidal swamp condition, and used 12 varieties and lines with Kapuas as control. Two lines had potential yield similar to that of the improved variety but the grain size and the taste acceptibility similar to that of local varieties
