Genetic Diversity Analysis of Elite Doubled Haploid Rice Genotypes for Yield Attributing Traits in White Nile State, Sudan

The development of new rice varieties is highly dependent on genetic diversity in desirable agronomic traits. Therefore, this study aimed to identify potential genotypes having the characters Korean (Tongil-type) and japonica developed through doubled haploid (DH) technology apply our breeding materials. 35 elite DH lines derived from another culture African along with two local checks were planted a randomized complete block design three replications during seasons 2019 2020. All evaluated exhibited wide significant variation ten measured highest heritability related high advance was recorded for number tiller/plant, grain yield t/ha, filled per panicle, thousand weights (g). Genotypic coefficient 1000 weight t/ha both seasons. Moreover, there positive correlation panicle (0.65), tiller/plant (0.64) m2 (0.54). Cluster analysis based components trait grouped 37 into four clusters. B largest consisted 13 genotypes. Finally, it could be concluded that, productive tillers, grain/panicle, m2, yield, KF170506, KF170509, KF170542, KF170530, KF170543, KF170500 KF170510 further selection type irrigated rice. In addition, hybridization these 7 high-yielding used achieve higher heterosis among Furthermore, evaluation useful developing reliable indices improving programs.
