Performance of lowland Green Super Rice Genotypes for the lowland rice Ecosystem in North-West Ethiopia
The experiment was conducted in Pawe and Assosa from 2016-2018 main cropping seasons with the major objectives of high yielding and disease resistance in the lowland production system. A total of 20 genotypes including two checks were used for the study. The trial was laid out in randomized complete block design with three replications with plot size of 7.5 m2. The combined analysis revealed that no genotype significant difference than the standard check on grain yield. This revealed that the tested genotypes failed to give high grain yield than the standard check (KOMBOKA) and there is no genotype for wider adaptability. The mean grain yield ranged from 2730.30kgha-1(G7) to 3683.40 kg ha-1 (G13). Even though all tested genotypes failed on combined analysis for both locations, the separate location combined analysis revealed that there is a significant difference on grain yield and other agronomic characteristics than the standard check. The separate location combined analysis revealed that there is a significant difference on grain yield and other agronomic characteristics than the standard check. In Assosa, one genotype (G13) and in Pawe two genotypes (G14 and G1) revealed significant different than the standard check and gave grain yield advantage of 26.7%, 21.7% and 20.6%, respectively than the check.
