![]() The addition of thiamin to potato-dextrose agar did not induce the formation of perithecia by isolates which produced no perithecia upon potato-dextrose agar. The addition of thiamin to Czapek`s medium was necessary for perithecium formation by isolates capable of forming perithecia on potato-dextrose agar. Half of te progeny of the cross of pathogenic X nonpathogenic isolates were apparently nonpathogenic to sweet potato. The progeny of the cross of two heterothallic strains included isolates apparently identical to the original homothalllic strain. Ascospore isolations from a homothallic strain gave rise to heterothallic strains. The results of these crosses suggest that a combination of at least two independently inherited genes are necessary for perithecium production. The ascospore progeny from perithecia formed by combinations of strains included the parental types alone, or both parental and recombination types. This subject prepares students for teaching in English medium, bilingual (Mori and English) and Mori medium (total immersion) educational settings. ![]() Isolates of still other strains did not produce perithecia alone or in combination with other self-sterile strains.

Teaching (Mori Medium/Te Kaupapa Arareo Mori) Te Kura Toi Tangata School of Education is committed to the education and development of Mori medium teaching. Long-necked perithecia formed on the line between self-fertile and certain self-sterile strains, as well as between certain self-sterile strains. Single conidium isolates from single-spore cultures were of the parental type. The ascospore progeny of 4 self-fertile strains included not only te parental self-fertile strains but its respective self-sterile strain. These strains were obtained from the ascosore progeny of cultures isolated from black-rot lesions on sweet potato or from the crosses of variants of the same origin. Ten strains of Ceratostomella fimbriata, differing in pathogenicity, morphology, and compatibility were isolated and described.
