ABSTRACT: We succeeded in producing mature seed from a line of Brassica rapa ssp. pekinensis that had
been hybridized with Raphanus sativus var. major. Our focus was on dominance of B. rapa ssp. pekinensis;
radish (R. sativus var. major)
had no influence.Marker tests for similarity showed
that the original CR291M-64 x HwiM-2 hybrid was an inbred CR291M-64, rather
than a genuine cross; this appears to have resulted from weak
self-incompatibility in this strain.The plants
from the mature seed bloomed with reddish flowers differently shown up to
present. The intergeneric hybrid between Brassica inbred and Raphanus hybrid was very weak in strength compared to the Brassica inbred which
was self-pollinated even though the cause of the weak was not identified. The hybrids
between Brassica hybrid, dominant and elite recessive, and Raphanus can
be developed in large quantities using mature hybrid seed without resorting to
ovule culture techniques.
