Effects of Self-Compatibility on Chance Crossing in Medicago sativa L.¹

Nineteen M. sativa clones were evaluated for percent pod set, seeds/pod, seeds/100 flowers tripped and ovules/-ovary. Pod set was significantly correlated with seeds/pod (r = +0.96). Ovules/ovary was not significantly correlated with either seeds/pod or pod set.

Eight of the 19 clones ranging in pod set from 6.9 to 91.2% averaged over 2 self-pollinations were selected to study the effects of self-incompatibility on chance crossing without emasculation. These 8 clones were used as females and hand crossed with and without emasculation to 2 different yellow-flowered clones as males. When the emasculated progenies were compared to the unemasculated progenies, only 1 of the 16 comparisons was significantly different with either the "t" test or X² of the frequency distribution.

The data suggested no relationship between percent self compatibility and selfing when hand crosses were made without emasculation.
