Mite Resistance

Mite resistance refers to genetic traits that confer tolerance or reduced susceptibility to spider mites and other arthropod pests commonly encountered in cannabis cultivation. These traits are often polygenic, involving multiple loci that contribute to pest defense mechanisms such as leaf surface characteristics, secondary metabolite production, or behavioral resistance. Lineage records frequently report mite-resistant phenotypes emerging from certain landrace populations and heritage cultivars, though the specific genetic markers remain largely undocumented in peer-reviewed literature. Breeders working in this category typically select for plants showing slower pest colonization, reduced feeding damage, or natural repellent properties under controlled pest exposure. Mite resistance is distinct from broad-spectrum pest management and should not be considered a substitute for integrated

Breeders incorporate mite-resistant germplasm through multi-generational selection and test crosses against known pest populations. Combining mite resistance with other agronomic traits requires careful phenotyping, as resistance mechanisms may be linked to undesired morphological or cannabinoid profile changes.
