| Esta investigación consistió en formar híbridos entre diferentes cepas de Lentinula edodes que presentaran equivalentes o mejores resultados y características que sus cepas progenitoras, Se evaluaron 16 cepas de Lentinula edodes. Para después realizar cruzas DI-MON entre las cepas de Lentinula edodes y los monospóricos de la cepa CP-7, y cruzas MON-MON entre los monospóricos de la cepa CP-7 y CP-188. Para el crecimiento micelial en masters, los híbridos DI-MON [97] X [7]32, [189] X [7]11 y [95] X [7]11, fueron los más precoces. Para el crecimiento micelial en bolsas, las cepas CP-172, CP-174, CP-188*, CP-97, CP-189, CP-7*, CP-163 y el híbrido MON-MON [7]32 X [188]29, fueron los mas precoces. Para la formación de costra café, el híbrido MON-MON [7]32 X... |

| ABSTRACT The eggplant is a highly valuable horticultural crop grown all over the world and it is of substantial economic importance in Asia. However, its production is severely threatened by several soil-borne and foliar diseases, insect-pests, drought, heat, and frost damage. Therefore, efforts to transfer useful resistance genes into eggplant from their wild relatives is important. In the present study, interspecific and intraspecific hybridization was carried out, that included three cultivated genotypes of eggplant (Solanum melongena MEE, Solanum melongena MEP, Solanum melongena MEB) and one wild Solanum species (Solanum incanum INC). The F1 hybrids were made by inter and intraspecific hybridization. A total of 632 possible inter and intraspecific... |

| ABSTRACT The commercial use of onion hybrids is preferred by producers. In contrast, the production of hybrid onion seeds is extremely inefficient. This is due to the use of lineages obtained by successive self-fertilizations assuming the effect of inbreeding depression per se. Therefore, it is necessary to understand new alternatives to reduce the effect of inbreeding depression in the strains. The objective of this study was to evaluate possible differences in polymorphism and levels of heterozygosity of strains obtained from intercrossed and self-fertilized plants. Twelve onion populations belonging to Bayer’s breeding program (Granex, IPA-1, IPA-2 and IPA-3) were used, obtained by self-fertilization of one plant, intercrossing of two plants or... |

| Salpichlaena is a distinctive fern genus characterised by 2-pinnate climbing fronds with indeterminate growth. The number of species in the genus has been a matter of debate. Taxonomic studies are made difficult by within-frond variability in pinna morphology and size, and by herbarium material being incomplete. We systematically documented 62 morphological traits in 283 herbarium specimens and sequenced 52 Salpichlaena and 11 outgroup specimens. DNA sequences included plastid genes (rbcL, rpoC1 and rps4), intergenic spacers (rps4-trnS, trnHpsbA and trnG-trnR) and a nuclear gene (pgiC). Phylogenetic analyses based on the plastid markers divided the samples into six major clades. We recognise the three deepest clades as distinct species (S. hookeriana, S.... |

| The first putative hybrid tree species of the genus Bruguiera (Rhizophoraceae), B. × rhynchopetala, is reported from mangrove forests of China and Australia. It was described from China previously as a variety of B. sexangula. The hybrid is acknowledged as B. gymnorhiza × B. sexangula with parent species restricted to different parts of the Indo-West Pacific. The hybrid is recognised at north-eastern and south-eastern parts of the overlap area between parent distributions, but it appears absent in western parts. Further local assessments are needed across the range. Hybrid status is supported by: 1) intermediate and shared morphological characters; 2) distribution limited to areas of co-occurrence of B. gymnorhiza and B. sexangula; and 3) molecular... |

| In the Himalayas, domesticated yak is fed at an altitudinal range of 3,000 to 5,000m. Below this zone, the cow is more common. Hybrids are fed at an intermediate zone. In order to analyze the genetic basis of milk protein variation, milk samples were taken from the nak (female yak), cow and their hybrid. By principle component analysis, yak and a highland type of cow (kirmcome) were clearly distinguished from midland (shakzam) and lowland (palang) cows. Local Sherpa people may produce suitable animals for each zone by controlling animal reproduction systems. Generally speaking, a sustainable stocking rate is two adult animals per hectare in the central Himalayas. However, most pastures were overgrazed 3 to 10 times more than this level. The feedstuff... |

| Abstract: The objective of this work was to evaluate the crossability between cassava (Manihot esculenta subsp. esculenta) cultivars and the subspecies M. esculenta subsp. flabellifolia and M. esculenta subsp. peruviana. Plants from the BRS Jari, BRS Formosa, BRS Verdinha, and BGM 2050 (Equador 72) cultivars were crossed with the two subspecies. During flowering, at pre-anthesis, pistillate flowers were covered with a nylon bag and staminate flowers on the same inflorescence were emasculated. The staminate flowers were collected and placed in flasks previously labeled and sterilized with alcohol; some fresh flowers were stored at room temperature due to asynchronous flowering. The crosses were made between 10 a.m. and 2 p.m. After pollination, the flowers... |

| ABSTRACT Layer hybrids are more superior in the egg yield than pure breeds. But this superiority causes some problems in the bones during the production period. There are a lot of differences among genotypes in the production period that have been examined extensively, however, the differences throughout incubation period aren’t known yet. Thus, the objective of this study was to evaluate the differences in femur properties of pure breed and layer hybrid embryos during the incubation period. A total of 354 fresh hatching eggs were used from one hybrid (Lohman White) and two pure breeds (Denizli & Gerze). The eggs were incubated. Hatching eggs from each genotype at the beginning of embryonic days (E) 19 and E21 were examined. At these embryonic ages, 12... |

| Abstract The productive potential of grapevine cultivars recently released in the market, especially for preparation of 100% grape juices, must be proved on the different Brazilian soil and climatic conditions of production, focusing on the Southwest of Paraná. The objective of this study was to evaluate the main yield components and chemical attributes of the juice of the following grapevine cultivars: Bordô, BRS Carmem, BRS Lorena, BRS Magna, BRS Rubea, BRS Violeta, Concord, Concord Clone 30, Isabel, Isabel Precoce, Moscato Bailey, Moscato Embrapa, Niagara Branca, Niagara Rosada and Seibel 5455. Paulsen 1103 was the rootstock used. The study was conducted during two harvests, 2015/2016 and 2016/2017, in Dois Vizinhos, Paraná State, Brazil. Due to the... |
