Abstract
Each one rooted cutting of seventy Ladino clover individuals derived from seven sources was transplanted in an insect-free cage, 2.5×5.5×2.0m, on May 20, 1964. Plants were irrigated frequently after transplanting to develop well-established plants for maximum self-fertilized seed yield and all the heads were picked immediately after fading of flower-stalks. The results obtained are as follows: 1) Twenty eight individuals produced self-fertilized seeds. Less than one seed per head were produced on 26 individuals except 2 individuals which produced 8.9 and 4.4 seeds per head respectively. 2) The rates of emergence of individuals which produced self-fertilized seeds did not vary with sources. 3) It was ascertained that the first flowering dates had no relation to the rates of self-fertility and the number of head had also no influence upon the number of fertilized seed. 4) Both numbers of head and flower which produced self-fertilized seeds were correlated with number of fertilized seed (r=+0.673 and + 0.923) respectively.
