Deployment of resistant varieties is a significant sustainable strategy for controlling CBB in marginal production systems. The objective of this study was to identify sources of resistance and the stability

Identification of two QTLs for resistance to Fusarium wilt race 1 in lettuce ( Lactuca sativa L.) Euphytica (IF 1.614) Pub Date : 2020-10-20 Kousuke Seki, Kenji Komatsu, Masahiro Hiraga, Keisuke Tanaka, Yuichi Uno, Hideo Matsumura
Fusarium wilt race 1, caused by Fusarium oxysporum f. sp. lactucae, is one of the main diseases of lettuce in tropical and subtropical regions, including under summer conditions in Japan. Resistant lettuce cultivars have shown symptoms on occasion, which have led breeding programs to focus on the improvement of resistance phenotypes to race 1. Disease assays using Fusarium wilt race 1 were performed

Characterization and absolute quantification of the Cellulose synthase-like F6 homoeologs in oats Euphytica (IF 1.614) Pub Date : 2020-10-16 Cristiano M. Zimmer, Guilherme Oliveira, Marcelo T. Pacheco, Luiz C. Federizzi
The Cellulose synthase-like F6 (CslF6) gene has been reported as a key factor for β-glucan synthesis in grasses. However, the action of this gene on oat β-glucan content is poorly understood. The objectives of this study were: (i) to quantify the absolute expression of CslF6 transcripts in oats under field conditions; and (ii) to characterize the CslF6 homoeologs in oat genotypes with different levels

Genome-wide association study (GWAS) reveals genetic basis of ear-related traits in maize Euphytica (IF 1.614) Pub Date : 2020-10-13 Lin Yang, Ting Li, Xiaokang Tian, Bingpeng Yang, Yonghui Lao, Yahui Wang, Xinghua Zhang, Jiquan Xue, Shutu Xu
Maize ear-related traits are important components of grain yield that directly influence maize production. The genetic basis of ear-related traits is still not completely understood, which would be helpful in the improvement of grain yield. In this study, to dissect the genetic basis of ear diameter (ED), ear row number (ERN), and kernel number per row (KNR), a genome-wide association study of maize

Unraveling yield-related traits with QTL analysis and dissection of QTL × environment interaction using a high-density bin map in rapeseed ( Brassica napus . L) Euphytica (IF 1.614) Pub Date : 2020-10-13 Yanping Xie, Jinsong Xu, Gang Tian, Lingli Xie, Benbo Xu, Kede Liu, Xuekun Zhang
According to the temperature and duration of the vernalization stage, three types of varieties adapted to different environments were bred in rapeseed breeding: spring, semi-winter, and winter type. Usually in a particular rapeseed producing area, only one type (spring or winter) is cultivated and almost none of the rapeseed varieties can adapt to both environments, which is mainly caused by the strong

Genetic basis of spring wheat resistance to leaf rust ( Puccinia triticina ) in Kazakhstan and Russia Euphytica (IF 1.614) Pub Date : 2020-10-08 Alexey Morgounov, Violetta Pozherukova, Jim Kolmer, Elena Gultyaeva, Aygul Abugalieva, Vladimir Chudinov, Oleg Kuzmin, Awais Rasheed, Askhat Rsymbetov, Sergey Shepelev, Aikerim Ydyrys, Minura Yessimbekova, Vladimir Shamanin
Kazakhstan-Siberia Network for Spring Wheat Improvement (KASIB) was established in 2000 to conduct multi-location cooperative yield trials for the exchange of breeding material and to evaluate agronomic traits such as grain yield and disease resistance. In 2016, aggregated KASIB data were analyzed and 120 cultivars and breeding lines demonstrating different degrees of resistance to leaf rust selected

Creation of a highly homozygous diploid potato using the S locus inhibitor ( Sli ) gene Euphytica (IF 1.614) Pub Date : 2020-10-07 Kazuyoshi Hosaka, Rena Sanetomo
Potato is a heterozygous autotetraploid crop propagated as tubers. Diploid potatoes, which are mostly self-incompatible due to gametophytic self-incompatibility, are often used to reduce genetic complexity. The discovery of the S locus inhibitor (Sli) gene has created a way to develop diploid inbred lines and perform F1 hybrid breeding in potato. However, residual heterozygosity found in advanced-generation

Phenotypic evaluation of elite spring bread wheat genotypes for hybrid potential traits Euphytica (IF 1.614) Pub Date : 2020-10-07 Samira El Hanafi, Najib Bendaou, Zakaria Kehel, Miguel Sanchez-Garcia, Wuletaw Tadesse
Wheat breeding has significantly contributed to enhancing yield potential and stability. However, one of the most promising technologies for further sustainable yield increases, hybrid wheat, is still limited due to lack of well-established heterotic groups and insufficient heterosis to compensate cost of hybrid seed production. Thus, optimizing the appropriate parents and combinations of floral and

Sensory analysis of arabica coffee: cultivars of rust resistance with potential for the specialty coffee market Euphytica (IF 1.614) Pub Date : 2020-10-06 Ivan de Paiva Barbosa, Antonio Carlos Baião de Oliveira, Renato Domiciano Silva Rosado, Ney Sussumu Sakiyama, Cosme Damião Cruz, Antônio Alves Pereira
The objective of this work was to describe the sensory profile of 11 arabica coffee genotypes with different levels of resistance to rust and to evaluate their genetic potential for the production of specialty coffees. The experiments were conducted in three coffee producing municipalities, in the region of Matas de Minas, in Minas Gerais state, Brazil. The experimental design was a randomized complete

Validation of marker-assisted selection in soybean breeding program for pod shattering resistance Euphytica (IF 1.614) Pub Date : 2020-10-06 Ji-Min Kim, Kyung-Hye Kim, Jiyeong Jung, Beom Kyu Kang, Juseok Lee, Bo-Keun Ha, Sungtaeg Kang
Significant yield losses are caused by pod shattering during the harvest of domesticated crop plants. The phenotype evaluation of pod shattering requires fully grown plants, and it is a labor-intensive and time-consuming procedure. The purpose of this study was to test the applicability of previously identified KSS-SNP5 SNP marker on chromosome 16 in the marker assisted selection (MAS) system for pod

Effects of growth conditions of donor plants and in vitro culture environment in the viability and the embryogenic response of microspores of different eggplant genotypes Euphytica (IF 1.614) Pub Date : 2020-10-06 Alba Rivas-Sendra, Patricia Corral-Martínez, Carolina Camacho-Fernández, Rosa Porcel, Jose M. Seguí-Simarro
Notwithstanding the importance of eggplant in global horticulture, doubled haploid production in this species is still far from being efficient. Although acknowledged to have a role in the efficiency of androgenesis induction, factors such as the growth conditions of donor plant or the in vitro culture environment have not been deeply explored or not explored at all in eggplant, which leaves room for

Molecular breeding of wheat lines for multiple rust and Fusarium head blight resistance Euphytica (IF 1.614) Pub Date : 2020-10-04 A. Maré, W. H. P. Boshoff, L. Herselman
Bread wheat is a widely cultivated crop with production that is often negatively influenced by disease outbreaks. Biological constraints in production include the wheat rusts (leaf rust, stem rust and stripe rust) and Fusarium head blight (FHB). Different strategies are available in the control of these important fungal diseases. However, resistance breeding remains the preferred option of control
