โœฆ Synopsis

An attempt to improve the self-incompatibility of an advanced inbred line of Brussels sprouts by selection has been unsuccessful . The apparent plant-to-plant variation in self-incompatibility has little or no genetic basis . It results from environmental effects and from intrinsic physiological differences between flowers on a single plant . A temperature rise from 17'C to 26'C markedly increases the self-compatibility of the lines tested, but no evidence was found for end-of-season compatibility . The best methods for producing inbreds with high and consistent self-incompatibility are discussed .

Experiments were made in which four different lines of Brussels sprout, each homozygous for S-allele 2, were tested for self-incompatibility at various stages of plant and flower development under different environmental conditions . The tests were made by counting the number of pollen tubes present

## Dominant S-alleles have been found to confer stronger self-incompatibility than recessive S-alleles in Brussels sprouts' inbred lines, but the overall effect is small and the degree of self-incompatibility associated with dominant S-alleles is often as great as that from recessives. Within the

Performance of a random array of recombinant inbred lines derived by single seed descent from five different source populations of Brussels sprouts (Brassica oleracea var. gemmifera) is presented. A total of 2,356 lines were tested in trials during 1985 and 1986. Three of the source populations were
