Four while clover (Trifolium repens L.) cultivars were evaluated for their seed setting capacity at Morioka, Japan. Results of 1991 and 1992 harvest years are reported. Large year to year and cultivar to cultivar variations in seed yield per floret were observed. A high percentage of unproductive ovules was observed. The results obtained also show that majority of ovule/seed abortion occurs within a 7-day period following pollination. Seed yield per floret was mainly influenced by weather conditions during the process of seed maturation. Results cleary illustrates the sensitivity of white clover to weather conditions.
