Self-incompatibility Alleles in Broccoli1

Abstract

Abstract Seven self-incompatibility ( S ) alleles ( S 2 , S 13 , S 15 , S 18 , S 24 , S 39 , and S 51 ) were identified in various hybrids and breeding lines of broccoli [ Brassica oleracea L. (Botrytis group)]. The international S . allele collection of Brassica oleracea at the National Vegetable Research Station was used to assure standardized identification.
