Fifteen rice genotypes were evaluated for their seasonal planting adaptation at Sukamandi Experimental Station Subang West Java during the dry and wet seasons of 2009-2010. Randomized complete block design with three replication was applied on the experiment. Plot size was 4 m x 6 m and plant spacing was 20 cm x 20 cm. Standart agronomic practices were applied on both planting season experiments. Data were collected for major morphological traits days to grain maturity and grain yield measured on wet and dry basis (11% moisture content). Data were analyzed for analyses of variance for each season and for combined seasons and mean values separation of the variable used the 5% Duncan Multiple Range Test. Correlation between grain yields and morphological variable data were computed for each season and for combined season. The correlation coefficients of variables and grain yield were partitioned into direct and indirect causes using path analyses. Combined analyses of veriances indicated significant effects of genotypes season and genotypes x season interaction for almost all variables including grain yields suggesting there were seasonal adaption specificity among genotypes. Five genotypes were identified as suitable for dry season planting and nine genotypes as suitable for wet season planting. Among those getypes there genotypes namels mekongga inprari-10 and OM 5240 were suitable for both dry and wet season plating. ciherang and cigeulis varieties were more suitable for dry season whele cibogo inpari-1 inpari-3 inpari-5 and inpari-8 were more suitable for wet season plating. adopting the most productive rice varieties for plating on dry or wet season as was suggested on this research should increase rice production substantially. to facilitate the availability of varieties adapted for a specific plating season rice breeding should purposedly apply a directional selection of lines suitable for specific plating season starting on the early generation of selection. 1.
