Most agricultural traits are controlled by quantitative trait loci (QTLs); however, there are few studies on QTL mapping of horticultural traits in pepper (Capsicum spp.) due to the lack of high-density molecular maps and the sequence information. In this study, an ultra-high-density map and 120 recombinant inbred lines (RILs) derived from a cross between C. annuum'Perennial' and C. annuum'Demp...

Genetic improvement of agronomic crops through breeding, which typically are marketed as commodities, are grower directed. Breeding objectives principally involve increasing yield, often based on resistance to biotic and non-biotic stress. For example improvement in hybrid maize yields have relied on increasing yield stability under high populations. In horticultural crops, breeding objectives ...

The intention of this review is to discuss floral initiation of horticultural trees. Floral initiation is best understood for herbaceous species, especially at the molecular level, so a brief overview of the control of floral initiation of Arabidopsis (Arabidopsis thaliana (L.) Heynh.) precedes the discussion of trees. Four major pathways to flowering have been characterized in Arabidopsis, inc...

Most tropical horticultural commodities are sensitive to chilling temperatures. Therefore, chilling injury (CI) is a serious problem in the postharvest handling of tropical horticultural commodities. From the standpoint of CI, we can classify all horticultural crops into three categories: A) chilling resistant; B) chilling sensitive; and C) slightly chilling sensitive. The storage life of commo...

Purpose – The purpose of this paper is to seek to show how the implementation of different quality assurance programs (QAPs) affects international market access for horticultural processing firms in developing countries. Design/methodology/approach – A representative survey of 50 registered firms processing horticultural produce in Vietnam was conducted. Logistic regression models are used to a...
