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 dif

β¦ Synopsis
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 group of recessive S-alleles differences have been found in their ability to give good self-incompatibility.
The implications in relation to breeding Ft hybrid Brussels sprouts 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
Partial dominance between S-alleles in the stigma was found to be common in 412 plants of Brussels sprouts in which two S-alleles could be detected. Amongst a further 168 plants in which only one S-allele could be detected, 5 plants showed the detected allele to be completely dominant to the other a
