Genetic and Environmental Factors Contributing to Reproductive Success and Failure in Potato

Abstract The foundation of potato ( Solanum tuberosum) breeding and the development new varieties is crossing parents to produce seeds that contain combinations alleles may be superior those in either parent. In this review, we begin by highlighting a signature problem breeding, widespread lack fertility observed many lines. We summarize normal male female reproductive structures, fertilization embryo growth. Various manifestations sterility are then described. These include defects meiosis mitosis, bud abscission, competition between structures tubers for resources, cytoplasmic sterility. Effects environmental determinants, such as temperature light intensity, on discussed. Finally, suggested best practices promote provided guide conducting genetics work with potato.
