Tom, a new diploid cultivar of Russian wildrye, Psathyrostachys juncea (Fisch.) Nevski, was developed by the Semiarid Prairie Agricultural Research Centre, Research Branch, Agriculture and Agri-Food Canada, Swift Current, SK. Tom is an eight-clone synthetic developed by recurrent selection for heavy seed weight and improved seedling emergence from deep planting. Tom represents a significant improvement in herbage yielding ability over the check cultivars Swift and Tetracan. Key words: Cultivar description, Russian wildrye, Psathyrostachys juncea (Fisch.) Nevski, seedling emergence, seed weight

Plant regeneration via tissue culture is becoming increasingly more common in monocots such as maize (Zea mays L.). Pollen (gametophytic) selection for resistance to aflatoxin in maize can greatly facilitate recurrent selection and the screening of germplasm for resistance at much less cost and in a shorter time than field testing. In vivo and in vitro techniques have been integrated in maize breeding programmes to obtain desirable agronomic attributes, enhance the genes responsible for them and speed up the breeding process. The efficiency of anther and tissue cultures in maize and wheat has reached the stage where they can be used in breeding programmes to some extent and many new cultivars produced by genetic manipulation have now reached the market.
