Variability, Heritability and Genetic Advance of Introduced Upland Rice Genotypes at Fogera in North Western Ethiopia

Variability, heritability and genetic advance are basic in order to provide information for plant breeding programs. Forty nine upland rice genotypes were tested 7*7 simple lattice design at Fogera Wereta station of Adet Agricultural Research Center 2012/13. The objectives the study estimate variability, tested. Analysis variance revealed that there was highly significant difference among 49 all characters studied. Accessions IR 78937-B-3-B-B-1 78937-B-3-B-B-2 had highest yield with a score 5374.5 kg/ha 5305.6 respectively. high yielding genotype advantage 57% 22.2%, respectively, as compared standard checks Nerica-4 Hidasie. Phenotypic coefficient variation (PCV) values ranged from 2.5% panicle length 49.98% number spikelet per panicle. While genotypic (GCV) 2.4% 47.6% Number tiller (22.47%), (49.98%), thousand seed weight (25.56%) (23.93%) higher PCV values. flag leaf (14.79%), width (16.12%), culm (16.42%) (16.32%) medium. Flowering cycle (7.81%), maturation (2.9%), (2.5%) lower GCV low flowering (7.21%), (1.82%) (2.4%); medium (14.26%), (15.39%), (15.19%) (15.72%); tillers (22.18%), (23.07%), (25.18%) (47.60%). these suggest impact is environmental influence lower. This generally indicated variability or divergence genotypes. Thus, improvement program through direct selection rather than lengthy crossing recommended.
