Clone x Tester Crosses on Compatibility Level of Sweetpotato (Ipomoea batatas L.)

Evaluation of compatibility on sweetpotato is very important to determine the crossing parents increase controlled cross-pollination. This research was aimed study level in cross-pollination based percentage normal seedlings obtained from crosses. The conducted at Kendalpayak Experimental Station ILETRI, Malang, Indonesia then followed by breaking seed dormancy and germination seeds obtained. genetic materials used were 17 accessions with high yielding potential 3 as tester for crossing. results showed that there differences levels combination their compatibilities male or female parents. Clone C-011 (Tester 2) most compatible parent, while clone C-141, C-007 C-131 C-127 3) both C-001 1) could not be parent due incompatibility.This information useful determining crosses open sweet potato order breeding efficiency.
