Abstract

Production of hybrid progenies between radish and allied genera.

Abstract

Eight species of 4 allied genera (Brassica fruticulosa, B. maurorum, B. oxyrrhina, Eruca sativa [E. vesicaria], E. vesicaria, Moricandia arvensis, Sinapis arvensis and S. turgida) and radish (Raphanus sativus) were used to investigate crossability in intergeneric reciprocal crosses. Chromosome association at metaphase I of PMCs in the F1 hybrids was observed to clarify partial homology between radish and allied genera genomes. The crossability between radish and allied genera largely depended upon the cross combination and the direction of the cross. Embryo rescue was useful for the production of F1 hybrids. Partial homology was confirmed between radish and allied genera genomes. Some synthetic amphidiploid lines, alien gene introgression lines and monosomic alien chromosome addition lines were bred in this study.
