Carrots are typically classified as annual or biennial, depending on their vernalization requirement for flowering, a trait that is genetically-conditioned. Wild carrots are predominantly annual, requiring less hours of cold temperatures for flower induction, whereas most cultivated carrots are biennial (i.e., they have higher cold temperature requirements). After vernalization, if followed by long...
Successful cross-breeding requires the investigation into the inheritance pattern of desirable traits. The present study recorded the segregation in coloration and analyzed anthocyanin concentration and composition in berry skin and flesh of the F1 interspecific populations (‘Beifeng’ × ‘Yan-73’) during the three successive growing seasons. All the progeny presented color in berry skin, whereas segregation...
Fusarium oxysporum f. sp. lactucae (FOLac) is responsible for significant economic losses across major lettuce-producing regions around the world. Thus far, only FOLac race 1 isolates have been reported associated with Fusarium wilt outbreaks in Brazil. The most sustainable strategy for disease control is the pyramidization of race-specific resistance factors in lettuce cultivars. The loose-leafy...
Ralstonia solanacearum is one of the causal agent of bacterial wilt in Brazil. This is the main bacteriosis in tomato plants, which can cause losses of up to 100% in their production. The use of resistant cultivars is the main form of control. Thus, the study of genetic control of resistance provides essential information for the conduct of breeding programs. The objective of this work was to study...
Fusarium wilt of bananas (Musa spp.), caused by Fusarium oxysporum f. sp. cubense (Foc) causes up to 100% yield loss in bananas. Foc race 1 in particular is very devastating to dessert bananas in Uganda. One of the effective control strategies for the disease is the development of resistant cultivars through breeding. The objectives of this study were to identify suitable banana germplasm for generating...
Citron (Citrullus amarus) is a watermelon (Citrullus lanatus) relative that is reported to carry disease resistance alleles to several important pathogens. It is therefore important to understand the inheritance of fruit quality traits while using this species to introgress resistance traits. Hence, the current experiment was carried out to determine the inheritance of important external and internal...
