Interpretive Summary:

Technical Abstract: Reciprocal crosses were made between rhizomatous birdsfoot trefoil (L. corniculatus L.) accessions and the autogamous germplasm AG-S4 to transfer rhizomes into an autogamous background. High success was obtained when AG- S4 was used as a maternal parent. Of 293 F1 progeny, 240 produced rhizomes under greenhouse conditions and a small number were autogamous. Hybridity of progeny was verified using morphological characters and RAPD analysis. In a random sample of progeny, pollen germination ranged from 2 to 53%. Among all progeny, pod and seed set appeared variable, indicating meiotic irregularities. Meiotic comparisons of parents and progeny were made. Number of univalents observed at diakinesis-metaphase I in the progeny ranged between 0-8, with the most having 2 or 4 univalents. Rhizomes were successfully transferred from a cross-pollinated to autogamous background. Further selection should lead to rhizome producing, autogamous lines with higher fertility.
