Rf4
from A619 maps distal to BNL13.05 on 8-S
--Paul H. Sisco
Rf4from the inbred A619 was shown
to be a single dominant gene for restoration of cms-C by Kheyr-Pour et
al. (Genetics 98:379-88, 1981) and was tentatively mapped to Chromosome
8 by A. Johnson using wx reciprocal translocation stocks (MNL 58:101-102,
1984). Using DNA extracted from backcross progeny from crosses using as
male A619 (Rf4/Rf4) and as females cms-C conversions of W182BN,
Oh51A, and NYD410 (rf4/rf4), we have found linkage between
Rf4and two RFLP loci, BNL13.05and BNL9.11(Chi-Square
= 47.8).
