Description
The objective of this study was to compare the virus-resistant white clover (Trifolium repens L.) germplasm SRVR with virus-susceptible cultivars for productivity and persistence under clipping in several different environments. Four cultivars and SRVR were broadcastseeded in the field at Mississippi State, MS in the fall of eight different years. Dry matter yields were taken for 2-4 years after seeding using mowers for defoliation. Virus-resistant SRVR had greater dry matter yields than all four cultivars in the second year, greater than three of four cultivars in the third year, and greater than two of four cultivars in the fourth year. Relative yields at the final harvest of each study and white clover ground cover were greater for SRVR than for the other white clover cultivars. Multiple virus resistance in SRVR improved white clover productivity and persistence under clipping.
