Abstract The objective of this work was to determine the genetic diversity, yield, and fruit quality of persimmon genotypes grown in the tropics, in order to select promising genetic materials. DNA extraction was performed on young leaves of 19 persimmon genotypes. For pomological characterization, 15 genotypes were selected. From each genotype, 50 fruit at the physiological maturity stage were harvested in the morning, in order to determine the following parameters: physicochemical characteristics; and the productive variables number of fruit per plant, average fruit fresh mass, average yield, and estimated average yield in two seasons. Twenty SSR markers were tested, out of which 12 were selected to evaluate genetic similarity, which allowed of the identification of distinct groups. The mean genetic diversity value found was 0.41, which is an indicative of low diversity among the analyzed persimmon genotypes. The 'Guiombo', 'Iapar 125', 'Kakimel', 'Mikado RJ', 'Rama Forte Tardio', and 'Taubaté' genotypes show a high yield. The genotypes classified as pollination-constant astringent ('Pomelo', 'Regina', 'Rubi', and 'Taubaté') and those classified as pollination-variant astringent ('Rama Forte', 'Guiombo', and 'Cereja') are potential materials for selection and genetic breeding programs due to their excellent fruit physicochemical characteristics. The investigation through molecular markers is an efficient approach to study the genetic diversity of persimmon genotypes grown in the tropics.
摘要本研究的目的是测定热带地区柿子基因型的遗传多样性、产量和果实品质，以选择有前途的遗传材料。对19个柿子基因型的幼叶进行了DNA提取。选取15个基因型进行形态学鉴定。从每个基因型中，上午收获生理成熟期的果实50个，以确定以下参数:物理化学特性;以及两季单株果数、平均果鲜质量、平均产量、估计平均产量等生产变量。对20个SSR标记进行了检测，选取了12个SSR标记进行遗传相似性评价，从而确定了不同的群体。平均遗传多样性值为0.41，表明所分析的柿子基因型多样性较低。“Guiombo”、“Iapar 125”、“Kakimel”、“Mikado RJ”、“Rama Forte Tardio”和“taubat”基因型产量较高。被归类为授粉恒定型收敛剂的基因型(“柚”、“雷吉娜”、“Rubi”和“taubat”)和被归类为授粉变异型收敛剂的基因型(“Rama Forte”、“Guiombo”和“Cereja”)由于其优异的果实物理化学特性而成为选择和遗传育种计划的潜在材料。分子标记研究是研究热带地区柿子基因型遗传多样性的有效途径。

Abstract The objective of this work was to estimate the genetic parameters and to evaluate the genotypic diversity of 12 'Tahiti' acid lime (Citrus latifolia) genotypes grafted onto two rootstocks. The experiment was carried out from July 2017 to January 2019, in the municipality of São Mateus, in the state of Espírito Santo, Brazil. Vegetative (stem diameter, canopy projection diameter, and plant height), productive (yield and fruit number), and fruit quality (fruit diameter, soluble solids content, and juice yield) traits were determined. A mixed model was used to estimate heritability and repeatability coefficients, as well as to predict clonal values. Scion diversity was determined through the standardized mean difference of Euclidean distances, and genotypes were clustered by modified Tocher. Clustering quality and trait importance were evaluated using the principal component analysis (PCA). Genotypic variance was observed, which is indicative of the possibility of selection of superior genotypes. The Tocher method showed the presence of three clusters, which is in alignment with the PCA results. The multivariate analyses allows of the selection and the recommendation of superior 'Tahiti' acid lime genotypes.
摘要以大溪地酸橙(Citrus latifolia)为材料，对嫁接到两根砧木上的12个基因型进行遗传参数估算和基因型多样性评价。该实验于2017年7月至2019年1月在巴西圣Espírito州的s o Mateus市进行。测定了营养性状(茎粗、冠突直径和株高)、生产性状(产量和果数)和果实品质性状(果粗、可溶性固形物含量和果汁产量)。采用混合模型估计遗传力和重复性系数，并预测克隆值。通过欧氏距离的标准化平均差来确定接穗多样性，并采用改进的Tocher聚类方法进行基因型聚类。采用主成分分析(PCA)对聚类质量和性状重要性进行评价。观察到基因型差异，这表明有可能选择优越的基因型。Tocher方法显示了三个聚类的存在，这与主成分分析的结果一致。多变量分析允许选择和推荐优良的“塔希提”酸石灰基因型。

Abstract The objective of this work was to evaluate different chemical treatments, associating herbicide combinations with the maintenance of forage species in the off-season, for the management of glyphosate-resistant sourgrass (Digitaria insularis) in a soybean crop. The experimental design was a randomized complete block in a 4×5 split-plot arrangement, with four replicates. The treatments consisted of: four combinations of the clethodim, glyphosate, haloxyfop-p-methyl, glufosinate ammonium, and s-metolachlor herbicides in the plots; green covers with the Massai, BRS Tamani, and BRS Zuri cultivars of Panicum maximum and with Urochloa ruziziensis, as well as fallow, in the subplots; and a control with the isolated application of glyphosate at the desiccation and post-emergence of the soybean crop infested with sourgrass and weeded. The herbicides tested before sowing and at post-emergence of soybean promoted a control above 90% of adult sourgrass plants until grain harvest. After harvest, there was a new emergence of sourgrass, mainly in the plots without green cover in the off-season. Overseeding soybean with forage species allowed of the establishment of these plants, which consequently interfered in sourgrass emergence and growth. The chemical treatments with herbicide combinations associated with the maintenance of forage species in the off-season are effective for the control of adult glyphosate-resistant sourgrass plants.

Abstract This review paper presents the current context of wheat production in Brazil, the management strategies to reduce yield losses due to blast, and the biotechnological approaches to improve wheat resistance. Wheat blast or brusone is caused by the Magnaporthe oryzae Triticum (MoT) pathotype fungus that can infect all the aboveground parts of the plant. The main symptom of the blast disease is spike bleaching that impairs grain production, causing yield losses up to 100% in susceptible wheat cultivars. The first world report of blast in wheat spikes was in Brazil, in 1985, and, currently, the disease is the main constraint to wheat cultivation in tropical and subtropical areas of the Cerrado and Mata Atlântica biomes. For a long time, the use of fungicides has been found to be ineffective under high-pressure disease conditions. However, recent works have pointed out that fungicide efficiency depends on the integration of other control measures, particularly the choice of cultivars with moderate resistance. In this review paper, the high variability of wheat reaction to MoT is presented, as well as a panel of resistant or moderately resistant cultivars (including non-2NS carriers), promptly available for cultivation in regions where blast is endemic.

Abstract The objective of this work was to evaluate the genetic variability of common bean (Phaseolus vulgaris) genotypes of different grain types as to macro- and micromineral concentrations, as well as to select superior genotypes by the multiplicative index. A total of 22 common bean genotypes were evaluated in experiments carried out in the dry and rainy seasons. The concentration of six minerals (potassium, phosphorus, magnesium, iron, zinc, and copper) was determined, and the multiplicative index was applied to individual and combined experiments. There was a significant effect of the genotype × environment interaction on the concentration of all minerals, and, when the genotype effect was decomposed into grain types, the genotypes differed as to the concentration of three or more minerals. There is genetic variability in the concentration of macro- and microminerals in the common bean genotypes evaluated in the dry and rainy seasons. In the combined experiments, high heritability estimates (≥ 62.60%) and a greater total genetic gain (283.59%) are observed. The multiplicative index applied to combined experiments allows the selection of superior common bean genotypes of the following grain types: red (Amendoim comprido and Light Red Kidney), cranberry ('BRS Executivo' and 'Hooter'), and carioca ('IPR Siriri'), which have high phosphorus and iron concentrations; Amendoim comprido also stands out for its high potassium concentration.
摘要本研究旨在评价不同粒型菜豆(Phaseolus vulgaris)基因型在宏微量元素含量上的遗传变异性，并利用繁殖指数筛选优良基因型。在旱季和雨季进行的试验中，对22个普通豆类基因型进行了评价。测定了六种矿物(钾、磷、镁、铁、锌、铜)的浓度，并将乘法指数应用于单个和组合实验。基因型-环境互作对所有矿物质的浓度均有显著影响，当基因型效应分解为颗粒型时，三种或三种以上矿物质的浓度存在基因型差异。在旱季和雨季评估的普通豆基因型中，宏微量元素的浓度存在遗传变异。在联合实验中，观察到较高的遗传力估计(≥62.60%)和较大的总遗传增益(283.59%)。应用组合试验的繁殖指数可以选择以下籽粒类型的优良普通豆基因型:红(Amendoim comprido和Light red Kidney)，蔓越莓(BRS Executivo和Hooter)和carioca (IPR Siriri)，它们具有高磷和高铁浓度;阿莫多也因其高钾浓度而引人注目。
