HPHIS paper reports results of 3 years of inbreeding work -*• with red clover to investigate the feasibility of developing inbred lines and selecting among and within them. Many early workers believed red clover was practically self-sterile. However, Fergus (1) in 1922 suggested that perhaps some self-fertile lines existed in the species. In 1921 he artificially self pollinated 650 individual heads, each on a separate plant. Thirty-two heads produced seed ranging in number from 1 to 24 with an average of 0.24 seeds per plant for all 650 bagged. Many abnormalities were found among the seedlings and many seeds failed to produce viable plants. Seventy-nine Sx plants were self pollinated in 1922, when 463 covered heads produced 1,034 seeds or 2.2 seeds per head.
