    Notes: Summary A number of inbred lines of Lolium perenne have been developed as far as the fifth inbred generation and are being used for basic studies on the cytogenetics of the species. An analysis on variation in the pattern of chiasma frequency and distribution, including the parent plants and all generations down to the S5, reveals that the effect of inbreeding is to reduce chiasma frequency and to increase both the cell and bivalent variances. Evidence is presented for a genetic basis of polygenic control of chiasma formation and distribution, and a model is suggested for control over the three related components of variation which involves a two-stage level of regulation.

    Notes: Summary An analysis of the patterns of chiasma distribution within bivalents, in a number of inbred lines of Lolium perenne, reveals a striking potential for variation in this character, as well as a polygenic genetic basis for its control. In parent plants the chiasmata have a regular pattern of localisation which restricts their formation to the ends of the chromosome arms: this strict localisation is progressively lost with inbreeding and novel patterns of distribution are found where chiasmata occur in more interstitial and proximal regions. The variation is continuous and originates from genotypic differences between the different parent plants, rather than from segregation among families deriving from individual parents.

    Notes: Summary In two contrasting types of S5 inbred Lolium perenne a correlation has been found between the distribution pattern of chiasmata within bivalents and that of meiotic U-type exchange. The relationship between the two processes is discussed, in terms of inbreeding effects upon chiasma redistribution, and mention is also made of some other types of chromosome breakages which arise following enforced self-pollination.
