Lettuce bacterial leaf spot caused by Xanthomonas campestris pv. vitians is an aggressive disease that is difficult to control. So far there are no reports of the reaction of biofortified lettuce genotypes to different isolates of the bacteria. Thus, the objective was to evaluate the aggressiveness of X. campestris pv. vitians, as well as the react...

In the improvement of pumpkins, the selection based on one or a few characters of interest tends to be less efficient, leading to a superior product only compared to the few characters selected. To maximize the simultaneous selection of multiple characteristics of interest, selection indexes are used to obtain a numerical value resulting from the c...

The culture of summer squash (Cucurbita pepo) has great socioeconomic importance worldwide. Characterization of C. pepo germplasm has been predominantly performed by field evaluations, which is very time consuming. Thus, the validation of new techniques capable of optimizing time for the field germplasm selection process would be useful. We evaluat...

The use of dwarf lines to obtain mini-tomato hybrids has provided agronomic and economic benefits. In Brazil, round tomatoes predominate over other varieties. The benefits of using a dwarf parent in round tomato hybrids has yet to be explored, making it important to develop dwarf round tomato lines. Backcrossing is the most suitable method to devel...

Tomatoes are an important crop in Brazil. In advanced stages of breeding programs, the capacity to select or reject tomato lines becomes complex. We selected tomato lines comparing different selection strategies. We evaluated 115 advanced tomato lines from the Tomato Germplasm bank of the Federal University of Uberlândia. The following characterist...

The genotypes evaluation in a germplasm bank is essential to determine their commercial or usefulness, as potential parents, in a breeding program. We aimed to detect the genetic diversity of 42 tomato genotypes of cherry type, belonging to the germplasm bank of the Federal University of Uberlândia and, also evaluate their behavior. The experiment...

Evaluation of pre-commercial hybrids in a germplasm bank is essential for determining its commercial potential or its utility as a potential genitor in a breeding program. The objective of this study was to determine genetic divergence and per se behavior of 47 pre-commercial hybrids from okra germplasm bank of the Universidade Federal de Uberlândi...

The mini tomato production has expanded, becoming an amazing alternative for enterprise. Despite all commercial potential, the cultivation has the occurrence of pests as main obstacle during the crop development. Nowadays, there are no researches that aimed obtaining genotypes with high acylsugar content, capable of providing a broad-spectrum resis...

High heterosis values can be obtained using hybrid okra seeds. However, despite high heterotic values, it is very difficult to produce hybrid okra seeds. The objective of this study was to evaluate an experimental methodology of hybridization. Two different methods of hybridization were used: traditional manual hybridization with complete emasculat...

The growth habit directly influences the tomato architecture, impacting on agronomic performance of mini-tomato hybrids. However, little is known about the growth habit of mini-tomatoes hybrids obtained by the crossing of dwarf lines versus normal lines with different growth habits. The objective of this study was to determine the type of growth th...

Little is known about the commercial potential of mini-tomato hybrids obtained from one dwarf parent. Thus, our objective was to evaluate the agronomic performance of mini-tomato hybrids obtained by crossing a dwarf line (A) with normal lines with indeterminate (I), determinate (D) and semi-determinate (SD) growth habits. The experiment was conduct...

Solar radiation is a component responsible for maintaining the life on the planet. Despite its importance, solar radiation is not recorded in most conventional meteorological station since not all have equipments to measure it, and then, it is usual to use empirical solar radiation estimation methods. In order to test and calibrate models for estim...

... Furthermore, to analyze the genetic dissimilarity between genotypes, we used Kohonen SOM, which is a computational intelligence strategy demonstrated to be efficient in identifying similarity patterns among genotypes and distinguishing and classifying them according to the distance between neurons in the network; as such, the shorter the distance, the greater is the similarity between genotypes contained in the respective neurons [33][34][35][36]. ...
... This can be achieved through introgression of genes belonging to wild species rich in allelochemicals, such as acylsugars. Acylsugar is mainly found in the glandular trichomes and promotes resistance to various pests by the mechanism of antixenosis (Maciel et al., 2018a, b;Peixoto et al., 2020). Combining broad resistance to pests and diseases, greater nutritional quality, and high yield in the same genetic material is the main challenge of breeders. ...
... In Brazil, tomatoes are classified into five categories: Minitomate, Salada, Caqui, Santa Cruz, and Saladete (Alvarenga, 2013). Outside Brazil, these tomato types are known as cherry or grape (mini-tomatoes), round, beefsteak, chonto, and saladette or roma, respectively (Finzi et al., 2020). Among them, the Santa Cruz fruit stands out with greater post-harvest durability, the highest yield potential, greater fruit uniformity, and a more intense red color (Shirahige, Melo, Purquerio, Carvalho, & Melo, 2010). ...
... Therefore, the difference between ET p and ET o needs further analysis. Many recent research involving ET p or ET o has focused on their variation, regional characteristics [12] or prediction [13], drought or drying analysis [14], vegetation responses [15], responses to drought [16], the influence of water resources on agriculture [17], and evapotranspiration rate estimations [18]. The studied timescales varied from monthly to annual [2,19], and the spatial scales varied from site [20] to multi-site [19], regional [21], national, and global. ...
... Few researches have been conducted into the biofortified lettuce (Cassetari et al., 2015;Jacinto et al., 2019;Silveira et al., 2019;Sousa et al., 2019). One of the main obstacles is to feasibly get an individual with both good agronomic traits and high level of carotenoids (Maciel et al., 2019a). ...
... The use of multivariate techniques to estimate genetic dissimilarity has become common and is employed in several species; tomatoes (Maciel, et al., 2018;Finzi, et al., 2019), common bean (Correa & Gonçalves, 2012), pumpkin (Ferreira, et al., 2016), corn (Nardino, et al., 2017) and soybean (Almeida, Peluzio & Afférri, 2011), with little research on coffee germplasm evaluation. In this context the objective of the study was to evaluate the Development, v. 9, n. 9, e561997468, 2020 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v9i9.7468 5 genetic dissimilarity among coffee cultivars based on hierarchical and optimization methods in the Alto Paranaíba region, MG. ...
... The different clustering patterns obtained from phenotypic data and SSR-based assay in the current study confirmed that the two approaches were distinct and highly variable. Numerous crop species have previously been the subject of disagreements over the relationship between morphological and molecular marker studies [77]. The variable properties of morpho-molecular parameters lead to differences in clustering patterns [59]. ...
... Phenotypic descriptors, based on morphological and agricultural traits, were widely used in the characterization of okra gene banks (YONAS; GAREDEW; DEBELA, 2014;ASGHAR, 2016;MACIEL et al., 2018). These traits are not adequate for the development of gene pools since they are influenced by environmental conditions and stage of plant development or detect only finite variation (TERZOPOULOS; BEBELI, 2008). ...
... There are few reports on okra germplasm diversity in Brazil (MATTEDI et al., 2015;MACIEL et al., 2017MACIEL et al., , 2018SILVA et al., 2021). Embrapa Hortaliças has one of the biggest okra germplasm banks in Brazil, which may hold important and strategic genetic diversity, but has not been characterized yet (SILVA et al., 2021). ...
... This result shows the success of the first generation of backcross and the restoration of part of the genetic constitution of the recurrent parent. Similarly, Maciel et al. (2017) reported positive results after the first backcross in mini-tomato (cherry tomato). ...
