The genetic basis of the antibiotic silk resistance was studied using silks from individual plants of resistant and susceptible inbreds and progeny in six generations (P1, P2, F1, F2, BC1, and BC2). Results of the scaling and chi-square tests for [Ab18 (susceptible) X Zapalote Chico] (resistant) and [GT114 (resistant) X GT119] (susceptible) indicated the additive-dominance model was unsatisfactory.
