“…The resistance of C. baccatum to Pepper yellow mosaic virus (PepYMV) can also be explained by the additive‐dominant model, but with the greater participation of the additive effects in the expression of the character (Bento et al, ). In contrast to this study, studies with other species of the Solanaceae family have also demonstrated that resistance to some diseases is highly influenced by additive effects (Chen et al, ; Singh, Rai, Singh, Saha, & Singh, ).…”

Anthracnose, caused by Colletotrichum spp., is one of the most common diseases affecting sweet pepper and chilli pepper production worldwide, especially in tropical and subtropical zones. This disease results in severe fruit damage both pre‐ and postharvest. The development of resistant cultivars is the most effective strategy for disease control, which requires knowing the genetic basis of resistance. In this study, we analysed the inheritance of resistance of Capsicum annuum to Colletotrichum scovillei at two fruit development stages. The ripe and unripe fruits were inoculated by conidia suspension, and anthracnose severity was evaluated for 8 days using a score scale. It was found that the inheritance of resistance has independent expression in ripe and unripe fruits. In both cases, two main genes are responsible for resistance with polygenic effects. Genetic control, with a quantitative aspect, is more affected by dominance than the additive effects, in both fruit development stages of C. annuum.

SUMMARYA total of 34 tomato genotypes (24 F1+10 parents) were tested for resistance to tomato leaf curl virus (ToLCV) disease by various whitefly inoculation techniques under field and insect-proof glasshouse (mass and cage) conditions. Of the ten tomato parental lines, two accessions [EC-520061 (Solanum habrochaites) and EC-521080 (Solanum pimpinellifolium)] were identified as highly resistant while four accessions (EC-520049, EC-528372, WIR-5032 and WIR-3957) of wild species were resistant to ToLCV. Out of the 24 F1 crosses, PBC×EC-520061, H-86×EC-520061, H-24×EC-520061 and DVRT-2×EC-520061 were found to be highly resistant against ToLCV disease. Biochemical (total phenol and total sugar concentration) and physiological (chlorophyll content and leaf area index) parameters were also used in healthy and disease-inoculated leaves of ten parents and six F1 hybrids to test the conformity of ToLCV-resistant and susceptible disease reactions. The results showed that among the 16 genotypes (10 parents+6 F1), EC-520061, EC-520049, PBC×EC-520061 and H-86×EC-520061 were stable for both biochemical and physiological markers while EC-521080 showed higher accumulations of total phenol and sugar concentrations and reduced leaf size between healthy and disease-inoculated leaves. The present study demonstrates the importance of the whitefly inoculation technique and biochemical and physiological markers in virus resistance screening programmes, and identifies a potential source of resistance to the ToLCV in Solanum species.

“…However, wild relatives of 167 tomato e.g. S. chmielewskii, S. habrochaitesand S. pimpinellifoliumwere found resistant 168 even with artificial screening [14]. The differences in the results of field-based screening 169 method could also be due to the difference in virus strain, vector genotype or altered 170 feeding conditions [47, 48] 171 Resistant), and S (Susceptible).…”

Eloquent information about the genetic basis of inheritance is important for any 8 breeding program. Therefore, a diallel study was conducted under the influence of tomato 9 leaf curl virus (TLCV) disease, using the eleven advanced lines of tomato. Firstly, the 10 information regarding percent disease index (PDI) was determined via artificial screening 11 with viruliferous whiteflies. Later, these lines were crossed in half diallel mating design to 12 produce fifty-five one-way hybrids. These hybrids and parental genotypes were 13 evaluated for seven morphological and three biochemical traits under open field 14 conditions. Using the Griffing approach (Method II and Model I) basis of inheritance of 15 traits were determined. Also, a Bayesian model was applied to the total yield descriptor. 16Correlations data indicated that total yield was not correlated with any other trait. The 17 significant general combining ability (GCA) and specific combining ability (SCA) 18values indicates exploitable genetic variation. The broad-sense heritability values were 19 larger than narrow-sense heritability, showing that selection will be efficient for the 20 improvement of these traits. Hybrid combinations H23, H42 and H49 can be 21 considered efficient for the selection of multiple traits, including yield. Overall, this study 22 provides a useful information regarding the genetics of important traits of tomato under 23 TLCV infestation. 24
