“…The inheritance of resistance to leafminers (L. sativae) in melon is of the dominant monogenic type according to the above observations. Other studies have reported similar inheritance in the genotypes 'Nantais Oblong' (DOGIMONT et al, 1999) and 'BAGMEL 56-R' (CELIN et al, 2017b). There are no known reports of polygenic genetic control of leafminers in melons.…”

“…The published list of melon genes includes resistance genes to diseases and pests of leaves, flowers, fruits, seeds, and in relation to productivity (DOGIMONT;SARI, 2022). Regarding insect resistance, the largest number of genes reported show resistance to Aphis gossypii (Hemiptera: Aphididae), while only the genes Lt (DOGIMONT et al 1999) and Ls (CELIN et al, 2017b) (DOGIMONT; SARI, 2022) have been reported for leafminers, highlighting the need for research into new sources of resistance and their characterization, thereby contributing to advances in the use of host resistance.…”

The use of resistant cultivars is an efficient and recommended method for the management of leafminers, which are the main phytosanitary problem in melons. The objectives of this study were to identify the sources of resistance to the leafminer in yellow melon accessions and to determine the resistance inheritance in acession AM-RT. Two field experiments were conducted in the municipalities of Baraúna, RN and Icapuí, CE, Brazil, to identify the sources of resistance. The design adopted was completely randomized blocks with 22 treatments and four replications. In this evaluation, the number of mines per leaf was quantified. The heterogeneity of the studied materials allowed for the identification of the accessions AM-RT and AM-TM as sources of resistance, considering that they revealed zero mines in the two evaluation environments. The accession AM-RT was selected and used to obtain the S1 population (by self-fertilization), S1:2 population derived from S1, and crossing between AM-RT and ‘Goldex’, which were evaluated in a third laboratory trial to determine the genetic control of resistance in that material. By the segregation pattern of the populations S1, S1:2, and the crossing (AM-RT and ‘Goldex’) and the estimation of the chi-squared (χ2) values, which were 1.33, 3.14, and 0.36, respectively, it was determined that the inheritance of resistance was controlled by only one gene with complete dominance. Therefore, in this study, two sources of resistance to the leafminer were identified, and resistance was conditioned by a gene with complete dominance in the accession ‘AM-RT’.

“…The same is true about other species in the genus Liriomyza . A single dominant locus model explained the resistance to a L. sativae in melon 45 . However, resistance to L. langei in spinach ( Spinacea oleracea ) is a complex trait presumably controlled by several genes with minor effects 46 .…”

Liriomyza trifolii (Diptera: Agromyzidae) is a leafminer that causes ruinous damage to many leafy vegetables including lettuce (Lactuca sativa L.) by stippling and tunneling the leaves. In this study, a population of 125 F3 families was developed from the intraspecific cross of ‘Valmaine’ (resistant) and ‘Okeechobee’ (susceptible) romaine cultivars for inheritance analysis and molecular mapping of the resistance loci controlling stippling damage. The experiments were conducted in an insectarium (controlled environment). Stippling damage proved to be heritable because the broad-sense heritability (H2) was 0.58. A segregation analysis suggested that a single dominant allele, Sd1 locus, controls resistance against L. trifolii. Furthermore, a quantitative trait loci (QTL) analysis identified one novel QTL, named Stippling on LG5 (qSTP5), flanked by two SNPs that were mapped to a 5.2 cM (8.5 Mb region) interval, explaining over 13% of the total phenotypic variance. Desirable allele for resistance to L. trifolii was derived from resistant cultivar Valmaine. Identification of SNPs closely linked to the QTL responsible for L. trifolii resistance should facilitate plant breeders to develop resistant romaine lettuce cultivars.

“…In Brazil, melon production is concentrated in the Northeast region, where the climate favors its cultivation under irrigation. The region accounts for over 95% of the national production, represented mainly by the states of Ceará and Rio Grande do Norte (Celin et al, 2017). The main melon-producing regions have semi-arid characteristics, which provide the best climate conditions for the crop.…”

Deficit irrigation (DI) strategies and soil cover are highly effective to improve the the water productivity in semi-arid regions. However, the effective monitoring of plant water status under DI strategies becomes crucial. The main objective of this study was to evaluate the use of thermal images to estimate the water status of melon plants cultivated in soil with and without mulching under different irrigation regimes. The experience was carried out from October to December 2018. The study was carried out in a randomized block design, in a split plot arrangement. Plots were composed by soil cover (with and without mulching with plant material), and subplots by 5 irrigation regimes (120, 100, 80, 60 and 40% of crop evapotranspiration-ETc), with five replicates. The following variables were evaluated: canopy temperature (Tcanopy), leaf water potential (Ψleaf), air temperature (Tair), soil moisture, crop yield and the thermal index (ΔT), this being defined as the difference between Tcanopy and Tair. ΔT showed high correlations with crop yield and crop water consumption, evidencing that thermography is an efficient tool to identify the water status of melon plants and could be employed for a proper irrigation scheduling under the tropical semi-arid scenarios. Moreover, the use of thermal images also allowed the identification of beneficial effects of soil cover on leaf water status and crop yield, mainly under moderate DI. The obtained results also demonstrate that mulching is essential to increase melon yield and water productivity in tropical regions.
