Extract

While the leaf resistance of many of Knight's B genes in a Sakel background is now much lower than that found in his original studies, that of B9K has remained unimpaired and this gene still segregates as a major gene. It is proposed to ascribe to the weak gene transferred by Knight from Wagad 8 (G. herbaceum) to Sakel the symbol B11, as gene homology tests between this gene and other B genes indicate that is non-homologous with them. The strong effect of environment on the expression of B11 was confirmed and it was noted that in Upland stocks B11 was much more effective than in Sakel, whereas the opposite was true of B9K.

While the leaf resistance of Bm Sakel is high its stem resistance is of a low level and it suggested that leaf, stem and boll resistance may be under the same control in some genetic systems but not in others.
