Crosing Relationships between Synthetic Lotus Amphidiploids and L. corniculatus1

A total of 236 trispecific hybrids were obtained from 15 out of 22 different cross combinations attempted between 12 Lotus amphidiploids and the cultivated tetraploid L. corniculatus. The relative ease with which these ~ross.~s have been produced, without resort to embryo culture, indicates that the transference of desirable germplasm from diploids to tetraploid L. corniculatus by means of experimentally produced amphidiploids can be accomplished without too much difficulty. Generally, the self-fertile amphidiploids were more suitable as seed parents than the self-incompatible L. corniculatus. From the crossing relationships of the various amphidiploids and L. corniculatus, it appears that L. japonicus and L. alpinus are more closely related to L. corniculatus than to the diploid taxa L. tilicaulis, L. schoelleri, L. krylovii, and L. corniculatus vat. minor. The highest percentage of successful crosses (85.15%) was realized when the amphidiploid (L. japonicus ✕ L. alpinus)2 was crossed with L. corniculatus.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
