Morphological characterization of Conyza blakei, Conyza bonariensis var. bonariensis, Conyza sumatrensis var. sumatrensis and Conyza lorentzii in the southeast of Buenos Aires (Argentine). The genus Conyza Less. includes ruderal species, which grow of ruderal habitat, roadsides and railways. They have also been cited as pasture weeds, annual and perennial crops under direct sowing (SD) systems, adapting to these slightly disturbed environments since they are sensitive to soil removal. The taxonomic identification of Conyza species linked to morphological characters is difficult in vegetative stages, since this genus has highly related and polymorphic species. With the objective of morphologically characterizing Conyza blakei, C. bonariensis var. bonariensis, C. lorentzii and C. sumatrensis var. sumatrensis were recorded 19 morphological characters (12 vegetative and 7 reproductive) qualitative and quantitative, in 35 plants of each species. These characters were analyzed by Multivariate Analysis (Analysis of Components and Main Coordinates). The morphological characterization made it possible to detect phenotypic differences between the Conyza species analyzed. The analysis of main coordinates allowed to differentiate the species both at a reproductive and vegetative level, while the analysis of main components only allowed to differentiate the species in reproductive stage.

For the foreseeable future, plant breeding methodology will continue to unfold as a practical application of the scaling of quantitative biology. These efforts to increase the effective scale of breeding programs will focus on the immediate and long-term needs of society. The foundations of the quantitative dimension will be integration of quantitative genetics, statistics, gene-to-phenotype knowledge of traits embedded within crop growth and development models. The integration will be enabled by advances in quantitative genetics methodology and computer simulation. The foundations of the biology dimension will be integrated experimental and functional gene-to-phenotype modelling approaches that advance our understanding of functional germplasm diversity, and gene-to-phenotype trait relationships for the native and transgenic variation utilised in agricultural crops. The trait genetic knowledge created will span scales of biology, extending from molecular genetics to multi-trait phenotypes embedded within evolving genotype–environment systems. The outcomes sought and successes achieved by plant breeding will be measured in terms of sustainable improvements in agricultural production of food, feed, fibre, biofuels and other desirable plant products that meet the needs of society. In this review, examples will be drawn primarily from our experience gained through commercial maize breeding. Implications for other crops, in both the private and public sectors, will be discussed.

Raden I, Nugroho CC. Syahrani. 2017. Identification and characterization of morphological diversity of Lemba (Curculigo latifolia) in East Kalimantan, Indonesia. Biodiversitas 18: 1367-1376. Lemba (Curculigo latifolia) is Kalimantan’s land prospective for commercial cultivation because its leaf fiber has been traditionally utilized as fiber source for ulap doyo woven cloth; its fruit as sweetener; and its root as medicinal herb. To this days, only a few of research has been conducted on lemba in East Kalimantan or even in Indonesia, including studies on lemba plant phenotype suitable for weaving material. Thus, a research about identification and morphological characterization of lemba cultivars is necessary to identify and characterize lemba plant in East Kalimantan to reveal phenotypic variability in both quantitative and qualitative traits that can be utilized as the source of germplasm for the plant breeding program. This study was carried out in three Sub-districts, i.e.: Tenggarong Sub-district (Kutai Kartanegara District), Kota Bangun Subdistrict (Kutai Kartanegara District), and Jempang Sub-district (West Kutai District). Data collection was done by observation, and measurement of quantitative and qualitative traits of lemba plant. Descriptive analysis was applied on the morphological traits data, while correlation analysis was performed to reveal relationship between the qualitative and quantitative morphological traits by using software Minitab v.14.12. Phenotypic variability was determined based on the standard deviation. Principal component analysis and cluster analysis of the data were performed by using software SPSS v.11.6. The variance value of the 33 observed lemba plant accessions from the three Sub-districts indicated that the phenotypic variability of the qualitative traits was narrow while that of the quantitative traits was broad. There are three principal components that account for the observed variability with a cumulative variance of 96% which is obtained from 19 observed traits. Cluster analysis at similarity 95% indicates that there are five lemba accessions groups based on only qualitative, only quantitative, or based on combined qualitative and quantitative traits.

Abstract Durian Kura-kura (Durio testudinarius Becc.) belongs to the Malvaceae family and is an endemic species of Borneo. Recently, genomic-based next-generation sequencing (NGS) approaches have been carried out for germplasm conservation and plant breeding programs. The NGS technologies allow plant genomes to be sequenced quickly and inexpensively and enable the efficient development of SSR markers through the in-silico approaches. This study aimed to develop and characterize simple sequence repeats (SSRs) from the assembled genome. The 1203929 scaffolds of the assembled genome were produced from the Ray assembler. The SSRs were identified and extracted using the MISA program produced 4315 sequences containing SSRs. The six motif repeats of SSRs were identified; consist of 431 sequences of dinucleotide (the most motif is AT), 3257 sequences of trinucleotide (the most motif is TTA), 516 sequences of tetranucleotide (the most motif is AAAT), 89 sequences of pentanucleotide (the most motif is ATTTT), 18 sequences of hexanucleotide and four sequences of heptanucleotide. The new SSRs markers will be used in further studies of genetic population of D. testudinarius and plant breeding programs.

<p>Se realizó la caracterización y evaluación morfológica de una colección del tomate tipo “cereza”, conocido comúnmente como "pajarito", o "vagabundo" (Lycopersicon esculentum var. cerasiforme), comparándola con el cultivar obsoleto de frutos de mesa de tamaño grande 'Marglobe' (Lycopersicon esculentum var. esculentum ). El estudio se llevó a cabo en el Centro de Investigación “La Selva”, de la Corporación Colombiana de Investigación Agropecuaria, Corpoica, ubicado a 2.120 msnm, con temperatura promedio de 17<sup>0</sup>C, en un área perteneciente a la formación ecológica de bosque húmedo montano bajo. Para el efecto, se registraron 39 variables de índole cualitativa y 11 de naturaleza cuantitativa. Se encontró polimorfismo en 34 de los 39 atributos cualitativos y en los 11de naturaleza cuantitativa. Los análisis de conglomerados cualitativos, cuantitativos y cualitativo-cuantitativo, no indicaron un patrón claro de distribución entre accesiones del Centro de Origen (Perú-Ecuador) y del Centro de Domesticación (México-Mesoamérica), con intercalamiento en los fenogramas de estos materiales y materiales de otras zonas del mundo. Los resultados señalaron amplia variabilidad cualitativa y cuantitativa y diversos niveles de arreglo de las variables a nivel de accesiones individuales, lo cual señala un amplio potencial de utilización per se de la colección y para programas de mejoramiento. EI fenograma cualitativo-cuantitativo, transformando la última categoría de variables a escalas aditivas binarias, con un máximo de cuatro intervalos por característica, permitió discriminar entre la variedad botánica cerasiforme y el cultivar de tomates grandes 'Marglobe', lo cual no fue tan evidente a nivel del fenograma cualitativo, construido en escala binaria, y el cuantitativo con base en distancias derivadas de variables estandarizadas.</p><p><strong><br /></strong></p><p><strong>Morphologic variability in the tomato pajarito (Lycopersicon esculentum var. cerasiforme), a precursor of cultivated tomato.</strong></p><p>To study the phenotypic variability of a “cherry” collection of tomato of the type in comparison with the vintage tomato cultivar 'Marglobe', an experiment was carried out at “La Selva”, Research Centre of Corpoica, located in Rionegro, Antioquia, at 2,120 masl, with an average temperature of 17<sup>0</sup>C and a relative humidity of 78%. Fifty descriptors were evaluated in this study, 39 were qualitative and l1 quantitative. Polymorphism was found in 34 out of 39 qualitative characteristics, and in the 11 quantitative variables. The qualitative, quantitative and qualitative-quantitative clusters analysis obtained with the polymorphic variables did not show a clear pattern of distribution between materials from the Origin Centre (Perú-Ecuador) and from the Domestication Centre (México-Central America). These results show ample qualitative and quantitative variability in the cherry type tomato collection, as well as ample distribution and arrangement of characters within individual accesions, which indicates the great potential to use this collection as well as in breeding programs. The qualitative-quantitative phenogram obtained by transforming the last type of variables to additive binary scales, with a maximum of four values by characteristic, exhibited discriminatory power between the cherry type tomato and the vintage cultivar 'Marglobe', which was not so clear for the qualitative phenogram based on binary values for the variables and for the quantitative phenogram based on distances obtained from standardized variables.</p>

The transfer of genetic variability from related species into crops has been a main objective for decades in breeding programs. Breeders have used interspecific genetic crosses and alien introgression lines to achieve this goal, but the success is always dependent on the interspecific chromosome associations between the alien chromosomes and those from the crop during early meiosis. In this Special Issue, the strength of chromosome manipulation in a breeding framework is revealed through research and review papers that combine molecular markers, cytogenetics tools and other traditional breeding techniques. The papers and reviews included in this Special Issue “Chromosome manipulation for plant breeding purposes” describe the development and/or characterization of new plant material carrying desirable traits and the study of chromosome associations and recombination during meiosis. New tools to facilitate the transfer of desired traits from a donor species into a crop can be developed by expanding the knowledge of chromosome associations during meiosis.

Identified germplasm is an important component for efficient and effective management of plant genetic resources. Traditionally, cultivars or species identification has relied on morphological characters like growth habit or floral morphology like flower colour and other characteristics of the plant. Studies were undertaken for identification and analysis of genetic variation within 34 rose cultivars through random amplified polymorphic DNA (RAPD) markers. Analysis was made by using twenty five decamer primers. Out of twenty five, ten primers were selected and used for identification and analysis of genetic relationships among 34 rose cultivars. A total of 162 distinct DNA fragments ranging from 0.1 to 3.4 kb was amplified by using 10 selected random decamer primers. The genetic similarity was evaluated on the basis of presence or absence of bands. The cluster analysis indicated that the 34 rose cultivars form 9 clusters. The first cluster consists of eight hybrid cultivars, three clusters having five cultivars each, one cluster having four cultivars, two clusters having three cultivars each and two clusters having one cultivar each. The genetic distance was very close within the cultivars. Thus, these RAPD markers have the potential for identification of clusters and characterization of genetic variation within the cultivars. This is also helpful in rose breeding programs and provides a major input into conservation biology.
