Other claims from this paper (7)
- Method / resource Pure summer squash lines differing in fruit shape were isolated.
- Observation F2 fruit shape segregated three-quarters disc to one-quarter sphere.
- Mechanism A single dominant major flattening factor was inferred to separate disc and spherical types.
- Observation Extracted spheres in two crosses were flatter than pure spherical types.
- Observation Extracted discs in two crosses were deeper than pure discs.
- Mechanism A second, weaker dominant flattening factor may explain deviations in extracted fruit shapes.
- Mechanism Evidence favored shape-determining factors over segregation of size factors.
