영문 초록

Interspecific crosses between three peanut cultivars(Arachis hypogaea) having different plant type, and four wild species, Arachis monticola, Arachis correntina, Arachis applisippla, Arachis rigonii were made by gibberellin(GA₃) treatment and the GA₃ effect on the interspecific crossability and growth of pollen tube in pistil was investigated. Pollen germination on the stigma and penetration of the pollen tubes into the style were increased by GA₃ treatment on the flower base. The GA₃ treatment increased pegging and pod formation up to 47% and 1.6% higher than those of control, respectively. Interspecific-crossability was varied with the combination of cultivar and wild species. Combination of Shipung-type variety Daekwangtangkong×wild species and Spanish-type variety Jinpungtangkong×wild species showed about 2% higher crossability than those of Virginia type variety Namdaetangkong×wild species. Arachis monticola among wild species showed the highest crossability with peanut cultivars, while Arachis correntina did the lowest. This result suggested that interspecific crossbility become higher in the cross between autoplyploids rather than those between allopolyploids.
