ABSTRACT Naturally-colored cotton fiber has received attention from breeding programs in the semiarid region of northeastern Brazil due to an increased interest in its fibers. Therefore, this study aimed to select genotypes of colored cotton fiber for agronomic and technological fiber characteristics for the Brazilian semi-arid conditions. The experiment was carried out in two environments (Patos-PB and Apodi-RN) in Brazil during the 2016 growing season. The experimental design was in randomized blocks with four replications. Treatments consisted of eleven colored fiber genotypes and three controls (BRS Topázio, BRS Rubi, and BRS Verde). The following traits were assessed: seed cotton yield (SCY, kg ha-1), lint percentage (LP, %), lint length (LEN, mm), lint strength (STR, gf tex-1), and lint micronaire (MIC, µg in-1). The data were submitted to individual and joint variance analyses, and means were grouped by the Scott and Knott (1974) test at 0.05 probability. Genotypes showed variability in all traits, which allows genetic gains in subsequent cycles of selection. The genotypes BRS Topázio, CNPA 2002 10245, and CNPA 2002 10327 presented the best estimates for the assessed traits, thus they can be selected for future studies in cotton breeding programs in the semiarid region.

Naturally Colored Cotton

The Northeastern region of Brazil comprises the Caatinga biome (900,000 km²) part of which is a semiarid region with rainfed and irrigated production systems. Among the successful breeding programs are cashew and cotton. The first led to a substantial increase in nut production in Ceará, Rio Grande do Norte and Piauí and the second bred a naturally colored cotton fiber, now processed in small clothing industries in Paraiba, exporting to 11 countries. In the lower-middle São Francisco valley, the previously grown onion was replaced by improved varieties, on 90% of the production area, and by industrial tomato, introduced by research in 1972, which came to be used on more than 80% of the area at the time. The participation of the private sector and continuity of breeding programs were crucial for the success. More examples of success are expected with the establishment of postgraduate courses in Agricultural Sciences in the Semiarid region.

Main Component

Naturally colored cotton is a green textile material. To cultivate new colored cotton and improve its performance, we must first understand the types, composition, and formation mechanism of the pigments in colored cotton. This study aims to explore the composition and structure of cotton fiber pigments. Qualitative analyses of pigment extracts from brown cotton, green cotton, and white cotton fibers were carried out using ultraviolet spectroscopy, diagnostic agents, and liquid chromatography–mass spectrometry. The main component of cotton fiber pigments was flavonoids, and specific types of flavonoids were found in the pigments in brown cotton, green cotton, and white cotton fibers. Research on the composition of cotton fiber pigments can increase our understanding of colored cotton fibers and lay a foundation for the cultivation, planting, and development of colored cotton fibers, as well the identification of naturally colored cotton from dyed cotton.

Sabendo de seu potencial econômico e a dúvida existente sobre sua taxonomia, foi realizada a caracterização de 60 indivíduos em três populações de cada uma das espécies com o uso de 41 descritores morfoagronômicos. Os dados foram analisados com o uso de estatística univariada e multivariada (estimativa de similaridade pelo índice de Gower e formação dos agrupamentos pelo método UPGMA). Foi encontrada grande variação na maioria dos descritores analisados dentro e entre populações e espécies. A população de Luz-MG apresentou os maiores valores relativos aos descritores de frutos e a de Corumbá-MS os menores. A análise de agrupamento revelou a formação de dois grandes grupos correspondentes às espécies analisadas e a subdivisão dentro de cada um destes corresponde a sua origem geográfica. A variação encontrada dentro de cada uma das espécies pode orientar a seleção de indivíduos mais produtivos em programas de melhoramento e a divergência entre espécies além de comprovar sua taxonomia subsidia futuros estudos e sua melhor utilização.   Palavras-chave: Acrocomia aculeata, Acrocomia totai, Arecaceae, diversidade, pré-melhoramento   GENETIC DIVERGENCE AMONG SPECIES OF PALM TREES Acrocomia Mart. BASED ON MORPHOAGRONOMIC DESCRIPTORS   ABSTRACT: The native palm trees Acrocomia aculeata and Acrocomia totai are used for several purposes, mainly, the use of fresh or processed pulp for food and the extraction of oil from the pulp and almond with different applications. Knowing its economic potential and doubt about its taxonomy, 60 individuals were characterized in three populations of each species using 41 morpho-agronomic descriptors. The data were analyzed using univariate and multivariate statistics (similarity estimate using the Gower index and formation of clusters using the UPGMA method). Great variation was found in most of the descriptors analyzed within and between populations and species. The population of Luz-MG had the highest values ​​for fruit descriptors and the population of Corumbá-MS the lowest. The cluster analysis revealed the formation of two large groups corresponding to the analyzed species and the subdivision within each of these corresponds to their geographical origin. The variation found within each species can guide the selection of more productive individuals in breeding programs and the divergence between species, in addition to proving their taxonomy supports future studies and their better use.   Keywords: Acrocomia aculeata, Acrocomia totai, Arecaceae, diversity, pre-breeding.

AbstractPlant quality trait improvement has become a global necessity due to the world overpopulation. In particular, producing crop species with enhanced nutrients and health-promoting compounds is one of the main aims of current breeding programs. However, breeders traditionally focused on characteristics such as yield or pest resistance, while breeding for crop quality, which largely depends on the presence and accumulation of highly valuable metabolites in the plant edible parts, was left out due to the complexity of plant metabolome and the impossibility to properly phenotype it. Recent technical advances in high throughput metabolomic, transcriptomic and genomic platforms have provided efficient approaches to identify new genes and pathways responsible for the extremely diverse plant metabolome. In addition, they allow to establish correlation between genotype and metabolite composition, and to clarify the genetic architecture of complex biochemical pathways, such as the accumulation of secondary metabolites in plants, many of them being highly valuable for the human diet. In this review, we focus on how the combination of metabolomic, transcriptomic and genomic approaches is a useful tool for the selection of crop varieties with improved nutritional value and quality traits.

Abstract Background In breeding programs, the selection of cultivars with the highest yield potential consisted in the selection of the yield per se, which resulted in cultivars with higher grains per spike (GN) and occasionally increased grain weight (GW) (main numerical components of the yield). In this study, quantitative trait loci (QTL) for GW, GN and spike fertility traits related to GN determination were mapped using two doubled haploid (DH) populations (Baguette Premium 11 × BioINTA 2002 and Baguette 19 × BioINTA 2002). Results In total 305 QTL were identified for 14 traits, out of which 12 QTL were identified in more than three environments and explained more than 10% of the phenotypic variation in at least one environment. Eight hotspot regions were detected on chromosomes 1A, 2B, 3A, 5A, 5B, 7A and 7B in which at least two major and stable QTL sheared confidence intervals. QTL on two of these regions (R5A.1 and R5A.2) have previously been described, but the other six regions are novel. Conclusions Based on the pleiotropic analysis within a robust physiological model we conclude that two hotspot genomic regions (R5A.1 and R5A.2) together with the QGW.perg-6B are of high relevance to be used in marker assisted selection in order to improve the spike yield potential. All the QTL identified for the spike related traits are the first step to search for their candidate genes, which will allow their better manipulation in the future.

Lentil is a versatile and profitable pulse crop with high nutritional food and feed values. The objectives of the study were to determine suitable locations for high yield and quality in terms of production and/or breeding, and to identify promising genotypes. For this reason, five lentil genotypes were evaluated in a multi-location network consisting of ten diverse sites for two consecutive growing seasons, for seed yield (SY), other agronomic traits, crude protein (CP), cooking time (CT) and crude protein yield (CPY). A significant diversification and specialization of the locations was identified with regards to SY, CP, CT and CPY. Different locations showed optimal values for each trait. Locations E4 and E3, followed by E10, were “ideal” for SY; locations E1, E3 and E7 were ideal for high CP; and the “ideal” locations for CT were E3 and E5, followed by E2. Therefore, the scope of the cultivation determined the optimum locations for lentil cultivation. The GGE-biplot analysis revealed different discriminating abilities and representativeness among the locations for the identification of the most productive and stable genotypes. Location E3 (Orestiada, Region of Thrace) was recognized as being optimal for lentil breeding, as it was the “ideal” or close to “ideal” for the selection of superior genotypes for SY, CP, CT and CPY. Adaptable genotypes (cv. Dimitra, Samos) showed a high SY along with excellent values for CP, CT and CPY, and are suggested either for cultivation in many regions or to be exploited in breeding programs.
