To make better use of cytogenetics in research on grasses and legumes, we need more information on— • Transferring characters between species and creat- ing new species through hybridization. • Restoring fertility in sterile hybrids. • Investigating the effects of chromosomal behavior and cytoplasm on seed-set. • Determining the effects of genetics and environ- ment on asexual seed-set. • Determining the origin and inheritance of asexual seed-set and male sterility. • Establishing the physiological consequences of changing the number of chromosomes. • Identifying mutagenic agents as well as the types and value of mutations. • Determining the origin and genetic behavior of natural and induced polyploids. • Isolating genetic markers for basic and applied N-31863 Grass specialists examine Kentucky bluegrass mutants at the Plant Industry Station, Bcltsville, Md. Mutations obtained by irradiation and chemical treatments are of value in studying gene action and inheritance in Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
