Red pepper ( Capsicum annuum L.), which is used as a pungent spice in foods and food products for flavoring and coloring, is one of the most widely consumed vegetables in the world ( Garces-Claver et al., 2007 ). In South Korea, dried red pepper
annuum L. cv. Cheonyang) were first surface-sterilized with 70% ethanol for 1 min followed by 4% (v/v) sodium hypochlorite for 20 min and the seeds were thoroughly washed with sterile distilled water. The capsicum seeds were germinated on Whatman No. 1
Sweet cultivars of Capsicum annuum L. are widely cultivated throughout the world because of their nutritional value, flavor, and color. However, bell peppers are susceptible to chilling injury (CI) below 7 °C ( Paull, 1990 ) depending on

Capsicum annuum , a vegetable crop of international importance, has rich genetic diversity for fruit traits. Much of this diversity has been exploited to develop sweet, blocky peppers that are most popular in commercial production and typically
Two studies were performed to evaluate techniques for screening verticillium wilt of Capsicum annuum L. The first study tested inoculation methods. The original method involved mixing the inoculum with planting medium in a cement mixer for 1 h. Seeds then were planted in the infested medium. In the new technique, inoculum is poured directly into the row, and seeds are placed directly on top of the inoculum. Inoculum levels of 2000 and 1000 mcrosclerotia/g of soil were tested in the new “in-row” method. The disease severity of the “in-row” plants was significantly less than the plants inoculated by the original method. A significant difference remained between resistant and susceptible lines. There was no difference between inoculum levels. The second study compared three commercial planting media to the standard soil used in previous screenings. Disease severity did not differ among media, and all media showed significant differences between resistant and susceptible C. annuum lines.
Inheritance of 10 quantitative traits related to plant and fruit development was studied in an intraspecific cross between a bell-type `Maor' [Capsicum annuum L. var. annuum (Grossum Group) `Maor'] and a small-fruited pungent chilli line `Perennial' [C. annuum var. annuum (Longum Group) `Perennial']. Estimates of broad- and narrow-sense heritabilities, coefficients of genetic variance, and genotypic correlations were obtained from the segregation of 120 F3 families in 2 years. Three of the traits analyzed, days to first ripened fruit, plant height, and pedicel length, exhibited heterosis and transgressive segregation. Days to first ripened fruit and total soluble solids had low narrow-sense heritabilities. The other traits studied had moderate to high narrow-sense heritability estimates. Most of the genetic variation associated with traits that affect the size of the fruit and its shape was additive. The highest genetic correlation coefficients among pairs of traits were found between fruit weight and each of the three width characters: fruit diameter, pericarp thickness, and pedicel diameter. In contrast, fruit weight had a low correlation coefficient with fruit length, indicating that the size of the pepper fruit in this cross was determined primarily by its width.
