Agro-morphological characterization of upland rice accessions Scientia Agricola
Nascimento,Wellington Ferreira do; Silva,Edson Ferreira da; Veasey,Elizabeth Ann.
The agro-morphological characterization is fundamental in order to provide information for plant breeding programs. The aim of the present study was to characterize 146 accessions of upland rice (Oryza sativa L.), based on qualitative and quantitative agro-morphological descriptors. The experiment was conducted in Recife, state of Pernambuco, Brazil, using a randomized block design with three replicates. Polymorphism was observed among 12 of 14 qualitative characters evaluated, whereas significant differences (p < 0.05) were observed for 11 of the 14 analysed quantitative traits. Genetic variance was higher than environmental variance and the average inheritability coefficients were above 80 % for all characters, which ensures the predominance of the...

Characterization of Capsicum germplasm collected in Northwestern Argentina based on morphological and quality traits Agriscientia (Córdoba)
Occhiuto,P.N; Peralta,I.E; Asprelli,P.D; Galmarini,C.R.
Paprika production is concentrated in Northwestern Argentina, where around 1500 ha are annually grown. Farmers mainly from Andean valleys, maintain their local landraces or &#8220;criollas&#8221; under different environmental conditions, using their farming traditions and selection criteria. These traditional varieties represent valuable genetic resources for conservation and selection of agronomical and quality traits. Between 2005 and 2007 eight collecting trips were made to Northwestern Argentina in order to recover local germplasm. As a result, five hundred new vegetable seed samples have been incorporated into the Germplasm Bank. Among these accessions 32 belong to Capsicum, the majority for paprika production, that were evaluated in field...

Characterization of diploid Arachis interspecific hybrids for pest resistance. Repositório Alice
PAULA, A. F. de; DINATO, N. B.; VIGNA, B. B. Z.; FAVERO, A. P..
In Brazil, the thrips (Enneothrips flavens Moulton) and rednecked peanutworm (Stegasta bosquella Chambers) are considered key pests for the peanut crop. Wild species show resistance to both of these pests, and can be used in breeding programs. The production of the sterile interspecific hybrids is necessary, which could be colchicine treated to get a synthetic amphidiploid with the same or similar genomic configuration of cultivated peanut. In this context, this study proposed the hybridization of wild pest-resistant species in 18 distinct combinations, obtaining the interspecific hybrids of Arachis and completing their characterization by (i) the reproductive characterization through pollen stainability with 2% acetocarmine (AC) solution with glycerin and...

Figueiredo,Alex Sandro Torre; Resende,Juliano Tadeu Vilela de; Schwarz,Kélin; Marodin,Josué Clock; Galvão,Alexandre Gonçalves; Resende,Nathalia Campos Vilela.
ABSTRACT Tomato is the most important vegetable species and has a strong bottleneck effect in its domestication and evolution. In exploring the existing genetic variability in commercial germplasm, germplasm has been proven to be an excellent alternative to obtain inbred lines in order to provide superior new hybrids in the future. In this sense, the objective of this study was to estimate the genetic distance among commercial processing tomato hybrids via agronomical and quality postharvest fruit traits with the aim of suggesting promising crosses for the formation of base populations for tomato breeding. Ten hybrids of processing tomato were evaluated in a complete randomized block design with three replicates. In total, eleven agronomic and postharvest...

Heliconia: rhizome propagation, shooting and clump area. Repositório Alice
LOGES, V.; COSTA, A. S.; GUIMARÃES, W. N. R.; LEITE, K. P.; CASTRO, A. C. R. de; CASTRO, M. F. A.; NOGUEIRA, L. C..
Heliconia cultivation is rapidly expanding in Brazil, mainly in the Northeast region. Usually, Heliconia rhizomes are directly transplanted to the field, which has been causing a high percentage of mortality, low shooting rates, and a long time to produce new shoots, depending on the genotype. This paper presents information on rhizome viability (RV), number of shoots per clump (NSC) during one year, and area occupied per clump (APC). The evaluations were carried out at the Heliconia Germplasm Collection of Federal Rural University of Pernambuco (UFRPE), Camaragibe - PE, Brazil. A randomized block design was used, with 30 treatments (genotypes) and 4 replications. The plant spacing was 3.0 m between plants in the rows and 4.0 m between rows. Differences...

Araújo,Cecilia MM; Silva Filho,Danilo F; Ticona-Benavente,César Augusto; Batista,Manoel Ronaldo A.
ABSTRACT Murupi chili pepper is a hot Amazonian pepper that has been used as flavoring in the region, yet its diversity is unknown. This paper aims to assess the diversity in 20 landraces from Peruvian, Colombian, and Brazilian Amazon. The experiment was installed in Manaus-AM, using a randomized complete block design with three replicates and five plants per plot. Analyses of variance showed significant differences for all nine descriptors. Fruit yield showed, in average, to be 208.08 fruits per plant, tantamount to 381.44 g per plant. Given 50% of relative distances estimated by generalized Mahalanobis distances and, nearest neighbor clustering, they displayed six groups. Cluster I comprised 50% of the landraces. Clusters IV, V and VI were represented by...

Pre-breeding: a link between genetic resources and maize breeding Scientia Agricola
Nass,Luciano Lourenço; Paterniani,Ernesto.
Activities related to genetic resources are characterized by high cost and long term return. Thus the conservation of genetic variability for the future and the efficient utilization of available accessions are two important goals to be attained. However, the low utilization of germplasm banks is not restricted to Brazil but to other developing countries as well. Therefore, pre-breeding is a promising alternative to link genetic resources and breeding programs. Several aspects for maize are discussed such as concept, importance, methods and results. Problems to be investigated and suggestions are also presented.

Sources of resistance against the Pepper yellow mosaic virus in chili pepper Horticultura Brasileira
Bento,Cíntia dos S; Rodrigues,Rosana; Zerbini Júnior,Francisco Murilo; Sudré,Cláudia P.
The Pepper yellow mosaic virus (PepYMV) naturally infects chili and sweet pepper, as well as tomato plants in Brazil, leading to severe losses. This work reports the reaction to the PepYMV of 127 Capsicum spp. accessions, aiming at identifying resistance sources useful in breeding programs. The experiment was carried out in a completely randomized design, with eight replications, in greenhouse conditions. Plants were protected with an insect-proof screen to avoid virus dissemination by aphids. Leaves of Nicotiana debneyi infected with the PepYMV were used as the inoculum source. Plants were inoculated with three to four fully expanded leaves. A second inoculation was done 48 hours later to avoid escapes. Only the youngest fully expanded leaf was...
