Title	The Ih, I, i allels in Hordeum deficiens genotypes of barley
Journal	Agronomy Journal
Year	1947
Volume	39
Pages	474-482
Author	Woodward R
Abstract	The deficiens character (designated Vt) for rudimentary floral structures in the lateral florets behaves as an allel of the V, v factor for the two-rowed vs six-rowed condition, and is at least partially dominant to them The VtVt genotype is sepitatic to the fertility alleles I, Ih, or i, but when crossed with a VdVdii tester stock the genotypes of these latter factors can be determined Deficiens varieties with IhIh, II, and ii genotypes were identified by this means Considerable variation in lateral floret fertility was noted between differences There also was considerable variation in lateral floret fertility from plant to plant within a given strain and between different heads on the same plant In several intermediums characterized by having relatively high numbers of lateral kernels, the percentage of lateral kernels was significantly higher in plants grown 6 inches apart in the row than in those seeded at higher rates The combined data, F2 and F3, from all crosses showed a recombination value of 14.1% +/- 0.36 for the genes VtVd and Prpr. For the more accurate F3 data, when taken alone, this value is 10.1 +/- 1.033.
