Yield and Yield Related Performance of Upland Rice Genotypes in Tselemti district, North Ethiopia, 2015

Abstract

Rice (Oryzasativa L.) is one of the major staple food crops for about 65 % of the world’s population. A rice fieldexperiment was conducted at Tselemti district of North Ethiopia during the main wet cropping season 2015-16 and2016-17. The current study was proposed to evaluate the adaptability and yield performance and to identify stable,high-yielding, disease-resistant and early maturing upland rice genotype(s) in local environments. Sixteen uplandrice genotypes including the standard check were evaluated. The tested genotypes are both released andunreleased genotypes and gained from national rice research programs. The experiment was laid out in arandomized complete block design of three replications. Combined analysis of variance revealed significantvariations in genotypes for most traits but there is non-significant for genotype by environment interaction based onthe selected analyzed traits and this implied the genotypes were not affected by the environment and the superioritygenotypes across environment is constant. The highest grain yield of 3.5 t ha-1 was recorded by G4-Tana (41.8 Qtha-1), followed by G2-Getachew (39.5 Qt ha-1). So, even if the stability didn’t analyzed the Genotype TanaandGetachew were relatively highest in mean grain yield across environments and hence, both genotypes could berecommended for cultivation by the farmers and this variety should be demonstrated and popularized in larger scaleto make use of its merits
