A blue aleurone stock, Montcalm, and Betzes ms-v were used to
estimate the recombination value between Bl and ms-v on chromosome
4. F2 data from the Betzes (ms-v ms-v bl bl B12 B12) x Montcalm
(Ms-v Ms-v B1 B1 Bl2 Bl2) cross were obtained by sorting
blue and white seeds from F1 plants, and planting each color in a separate
plot. The number of male sterile and fertile plants in each plot are given
in Table 1. A recombination value of 11.0 + 1.3% was estimated according
to the maximum likelihood method (l).
Data from a Betzes ms-v x Hubamer cross, and from other linkage
studies with Bl and Bl2 will be available at a later date.

fertile plants from blue and white seeds.
