Subterranean clover pollen germinates freely on an agar medium at relative humidities above 95 per cent. and at temperatures between 20 and 25°C. Temperature was not as critical as relative humidity, since pollen germinated freely a t 4°C. Based on these findings an improved technique for the artificial hybridization of subterranean clover varieties was developed. With this technique 35.3 per cent. of the emasculated and cross-pollinated florets set seed in 18 different intervarietal crosses. Varying degrees of compatibility exist between different varieties. The percentage of emasculated florets in Tallarook which set seed from pollinations with different male parents varied from 75 per cent. for Dwalganup to 6.5 per cent. for Wenigup. The characteristics of a number of the F1 hybrids are described. The extent to which different parental characters were dominant in the hybrids is indicated.

An improved technique for successful artificial hybridization in annual medic (Medicago spp.) is described. Using a previously reported method, only four out of seven species were successfully crossed, with the percentage of success ranging from 3 to 22%. Initial modifications to this technique gave a 7-8 fold increase in the successful crossing rate in M. murex and M. polymorpha medic, from 9 to 64% with M. murex and from 10 to 82% with M. polymorpha. Further modifications to the technique resulted in a success rate of 100% in both species. The numbers of seeds per pod obtained from crosses in both species were also increased by using the modified techniques compared to the established method. Selection of larger, more mature flowers, differences in flower cutting position, as well as post pollination position were the main modifications which accounted for the greatly improved success rate. The modified technique was subsequently applied successfully to obtain for the first time inter-specific crosses involving M. polymorphax M. murex, M. polymorphax M. sphaerocarpos, M.murexx M. sphaerocarpos, M. solerolii x M. littoralis/M.truncatula hybrid, M. solerolii x M, tornata, and M. littoralis/M.truncatula hybrid x M. sphaerocarpos.
