Abstract/Contents:An analysis of the patterns of chiasma distribution within bivalents in a number of inbred lines (four derived from variety S23, and nine German inbred lines) revealed considerable variation in this character as well as a polygenic basis for its control. In the outbred parent plants the chiasmata had a regular pattern of localization which restricted their formation to the ends of the chromosome arms; this strict localization was progressively lost with inbreeding and novel patterns of distribution were found where chiasmata occurred in more interstitial and proximal regions. The variation was continuous and originated from genotypic differences between the different parent plants, rather than from segregation among families derived from individual parents.
