Floral Response, Winter Survival, and Leaf Mark Frequency of Advanced Generation Seed Increases of ‘Bollard’ Red Clover, Trifolium pratense L1

R. J. Bula, R. G. May, C. S. Garrison, C. M. Rincker and J. G. Dean2

Varietal changes of Dollard red clover (Trifolium pratense L.) seed lots were of much smaller magnitude from the second to the third generations of increase than from the first (breeder) to second generations of increase. Changes in varietal populations during seed increases at Shatter and Tehachapi. Calif, were more pronounced than during similar increases at Prosser, Wash. Shifts toward more flowering type and fewer winter-hardy plant populations were noted for some seed lots produced at Shatter and Tehachapi. However, under certain management treatments, the varietal populations from seed produced at these two locations were similar to the plant populations of the first generation seed. Seed produced at Prosser resulted in plant populations similar to those of the first generation seed. Changes induced at Prosser were toward more nonflowering and more winter-hardy type plants compared to the first generation seed.

A high correlation was noted between plant type and winter survival. No relationship was found between plant type or winter survival and leaf mark.

Key Words: Genetic shift • Seed production
