摘要： Wild peanut (Arachis) species are promising sources of disease resistance for improving peanut cultivars. The objective of this study was to assess cross-compatibility among cultivated and wild peanuts in crosses between eight peanut cultivars and 27 wild species carrying the A, B, E, Ex, F, K, P, and H genomes. Embryo culture and chromosome doubling led to polyploids representing hybrids between cultivated peanut and A. stenosperma, A. macedoi, A. duranensis, A. villosa, and A. diogoi. The first two showed greater resistance to bacterial wilt than their cultivated parents. DNA markers were developed for verifying the hybrids and for identifying translocation or introgression lines with alien chromosome fragments.
