The study examined the reproductive indices of albino and normal pigmented Clarias gariepinus fish from Katsina (KT) Yola (YY), carried out under hatchery condition. experiment compared fecundity, testes, milt volume, percentage fertilization hatchability (AA) (NN) (YY). Normal C. had highest number eggs (229,240), followed by YY (127,250) least was recorded in Albino (124,750). weights lengths...

The results of the study phenotypic dominance in F 1 and degree transgression F2 by elements productivity: number mass grains length main ear soft winter wheat are presented. selection parental components for crossing was formed according to scheme 7x7 diallel crossings: productivity (Podolianka, MIP Kniazhna, Yuvileina, Dovira), nutritional direction (Chornobrova, Biliava, Sofivka). In 1, spik...

interspecific hybridization occurs among cucurbia species it is commonly used for grafting, yield increasing and production of pest resistant rootstocks. in the present research probability of interspecies hybrid generation among seven lines of cucurbita pepo (p1, p4, p5, p6, p10, p22, p25) and six lines of cucurbita moschata (mo3, mo5, mo6, mo9, mo11, mo12) were investigated. after crossing of...
