Near-isogenic lines of various genetic markers and interchanges

Near-isogenic lines of genetic markers and interchanges are useful for a variety of genetic, biochemical, and physiological studies. This report summarizes the backcross program we have carried out for over 10 years (see tables), and is an updated version of the 1979 report (MGCNL 53:114-115).

Genetic markers are isolated in homozygous condition after six backcrosses. Certain backcross lines are now being combined to produce multiple marker stocks. Sixth backcross interchange lines are simply selfed; no attempt has been made to isolate homozygotes.
