Panama disease new, already infected plant is fairly high. Finally, the disease is known to infect certain weeds without showing symptoms, meaning it can survive in the absence of banana plants and remain undetected in a place where bananas are planted later. FOC is thought to persist only asexually, as a teleomorph or sexual phase has not been found and no recombinant genotypes have been observed. This means that the survival and dispersal of the disease relies on purely asexual spores and structures. The disease survives in chlamydospores which are produced as the plant dies and can survive in the soil for
Crop diversity can be the result of genetic differences: a crop may have genes conferring early maturity or disease resistance Such traits collectively determine a crop's overall characteristics and their future potential. Diversity within a crop includes genetically-influenced attributes such as seed size, branching pattern, height, flower color, fruiting time, and flavor. Crops can also vary in less obvious characteristics such as their response to heat, cold, a drought, or their ability to resist specific diseases and pests. Modern plant breeders develop new crop varieties to meet specific conditions. A new variety might, for example, be higher yielding, more disease resistant or
