Natural hybridization is attracting much interest in modern speciation and conservation biology studies, but the underlying mechanisms remain poorly understood. In particular, it is unclear why enviro
ABSTRACT The aim of this study was to develop bell pepper hybrids with resistance to multiple pathogens and make inferences in regard to components of heterosis in hybrids obtained from lines presume
Although hybrid crop varieties are among the most popular agricultural innovations, the rationale for hybrid crop breeding is sometimes misunderstood. Hybrid breeding is slower and more resource-inten
Deciphering the genetic and developmental causes of the disproportionate rarity, inviability and sterility of hybrid males, Haldane's rule, is important for understanding the evolution of reproductive
