Abstract
Seven types of monosomic addition lines of radish with single kale chromosome (a∼g) have been bred by successive crossings of synthetic arnphidiploid Raphanobrassica (2n=36, RRCC) with radish (Raphanus sativus L., 2n=18, RR) (KANEKO, et al. 1987). In this paper, the transrnission rate of each kale chromosome in these seven monosomic addition lines was estimated by studying their morphology, and chromosome number as well as pollen and seed fertility. The materials used in this paper were the progenies derived from the reciprocal crosses between the seven monosomic addition lines (B1F1) and radish, the intercrosses among different addition lines, the sibcrosses of each type and the intercrosses between different addition lines.
