Persistence of Hard Seed in Vicia Lines Derived from Interspecific Hybridization1
- E. D. Donnelly2
Four advanced-generation, hard-seeded vetch lines (Vicia sativa type) from V. sativa L. × V. covdata Wulf. were studied for persistence of the hard seed characteristic in subsequent generations. Lines differed in persistence of hard seed. Two lines produced approximately 75% hard seed over a 3-year period whether planted from successive generations of hard seed only or from hard and soft seed as produced. Two other lines that received these same treatments averaged over the 3-year period 26 and 30% less hard seed when hard and soft seed were planted each generation than when hard seed only were planted. Data indicated that two lines were homozygous for the gene or genes conditioning hard seed and that two lines were segregating.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
