13. A multiplex PCR system for detection of wide compatibility allele S5-n and erect panicle allele dep1 in rice
Abstract Wide compatibility and erect panicles are important traits for heterosis and ideal plant type breeding in rice and accordingly are targets for rice yield improvement. In this study, a multiplex PCR system based on functional markers was developed to simultaneously identify genotypes of the wide compatibility allele S5-n and the erect panicle allele

14. Behavior of grape breeding lines with distinct resistance alleles to downy mildew (Plasmopara viticola)
Abstract Downy mildew (Plasmopara viticola) is the main grapevine disease in humid regions. In the present investigation, marker-assisted selection (MAS) was used to develop grapevine lines homozygous in loci Rpv1 and Rpv3 for resistance against P. viticola. The experimental populations UFSC-2013-1 (n = 420) and UFSC-2013-2 (n = 237) were obtained by self-po

15. Polymorphisms and their Haplotype Combinations in the Lysozyme Gene Associated with the Production Traits of a Chinese Native Chicken Breed
ABSTRACT Animal lysozymes, which have been studied in many of invertebrate and vertebrate species, have been characterized and demonstrated to be immune-associated molecules, digestive enzymes and multifunctional molecules. The purpose of this study was to detect the connection between lysozyme-gene polymorphism and the production traits of a Chinese native

16. Linkage and mapping of quantitative trait loci associated with angular leaf spot and powdery mildew resistance in common beans
Abstract Angular leaf spot (ALS) and powdery mildew (PWM) are two important fungi diseases causing significant yield losses in common beans. In this study, a new genetic linkage map was constructed using single sequence repeats (SSRs) and single nucleotide polymorphisms (SNPs), in a segregating population derived from the AND 277 x SEA 5 cross, with 105 reco

17. QTL mapping for yield components and agronomic traits in a Brazilian soybean population
Abstract The objective of this work was to map QTL for agronomic traits in a Brazilian soybean population. For this, 207 F2:3 progenies from the cross CS3035PTA276-1-5-2 x UFVS2012 were genotyped and cultivated in Viçosa-MG, using randomized block design with three replications. QTL detection was carried out by linear regression and composite interval mappi

18. Genome-wide association study of drought-related resistance traits in Aegilops tauschii
Abstract The D-genome progenitor of wheat (Triticum aestivum), Aegilops tauschii, possesses numerous genes for resistance to abiotic stresses, including drought. Therefore, information on the genetic architecture of A. tauschii can aid the development of drought-resistant wheat varieties. Here, we evaluated 13 traits in 373 A. tauschii accessions grown under

19. Genome selection in fruit breeding: application to table grapes
ABSTRACT Genomic selection (GS) has recently been proposed as a new selection strategy which represents an innovative paradigm in crop improvement, now widely adopted in animal breeding. Genomic selection relies on phenotyping and high-density genotyping of a sufficiently large and representative sample of the target breeding population, so that the majority

20. NCAPG is differentially expressed during longissimus muscle development and is associated with growth traits in Chinese Qinchuan beef cattle
Abstract Based on RNA-seq analysis, we recently found that the bovine NCAPG (non-SMC condensin I complex, subunit G) gene is differentially expressed during development of the longissimus muscle. In the present study, we validated this result and, using quantitative real-time PCR analysis, identified two adjacent genes, LCORL and DCAF16, that are more abunda

21. Inheritance patterns and identification of microsatellite markers linked to the rice blast resistance in BC2F1 population of rice breeding
The BC2F1 population was derived from a cross between rice variety, MR219 (susceptible to blast) and Pongsu Seribu 1 (resistant to blast). The objectives of this research were to know the inheritance pattern of blast resistance and to identify the linked markers associated with blast resistance in BC2F1 population. Sixteen microsatellite markers were found a

24. Genetic architecture of purple pigmentation and tagging of some loci to SSR markers in pearl millet, Pennisetum glaucum (L.) R. Br.
This report describes the construction of integrated genetic maps in pearl millet involving certain purple phenotype and simple sequence repeat (SSR) markers. These maps provide a direct means of implementing DNA marker-assisted selection and of facilitating "map-based cloning" for engineering novel traits. The purple pigmentation of leaf sheath, midrib and
