Genetic improvement of Capsicum frutescens: hybrid vigor for anthracnosis resistance and production traits

Capsicum annum L. Storability Vigor and Estimation of Its Genetic Parameters

“…Seed deterioration at RH 90-95% causes chili seeds faster physiological damage. According to (Amorim et al, 2021), Humidity and hot temperatures can encourage growth of fungi. It can damage the components of the seed and can affect the quality of the seed.…”

“…The seed vigor testing method validated by ISTA (2007) (International Seed Testing Association) is the AA (accelerated aging) fast aging method and the conductivity test (electrical conductivity). Amorim (2021), investigated the relationship between seed shelf life vigor and seed deterioration and found that rapid shrinkage techniques were compatible with reduced seed quality in high-temperature storage. Based on research by McLeod et al, (2023) on seed deterioration and rapid depreciation methods in chickpea seeds (Arabian Bean) showed that the seeds that faced the seed damage positively correlated with the seed that faced the rapid damage.…”

UNEMAT Pedro and UNEMAT Malagueta Pantaneira: New pepper cultivars with increased resistance to anthracnose

“…The UNEMAT Pedro cultivar is a line derived from the UNEMAT 44 accession, which was collected in the city of Cáceres, state of Mato Grosso (lat 16° 04' 14'' S, long 57° 40' 44'' W). After the resistance to anthracnose, fruit potential, and production of this cultivar were assessed (Amorim et al 2021), two rounds of mass selection were conducted to further improve its desirable traits (Figure 1).…”

“…In this context, the key technological advantage of the UNEMAT Pedro and UNEMAT Malagueta Pantaneira cultivars is their increased resistance to anthracnose, the main post-harvest disease in this crop. This resistance is a significant advantage in disease management (Amorim et al 2021). The intensity of anthracnose affecting the fruits of UNEMAT Pedro (1.83 mm²) and UNEMAT Malagueta Pantaneira (1.74 mm²) was significantly lower than that for the fruits of susceptible commercial cultivars (114.22 mm²) (Table 2), demonstrating a high resistance, which, in turn, results in a longer shelf life for the fruits.…”
