Abstract

The changes in chiasma frequency under different degrees of inbreeding were studies in P. typhoides (2n = 14) and in B. campestris 'Brown Sarson' (2n = 20). An increase was observed in the mean chiasma frequency per cell of P. typhoides and B. campestris inbreds compared with the outbred populations. "However, the changes in the magnitude of the chiasma frequency under inbreeding varied from population to population, in the populations from the same country and among populations grown in different years". This differential response is examined in relation to the past history of selection, the genetic diversity of the populations, the ecological conditions under which they are grown and the nature of the breeding system
