Mapping QTL conferring speckled snow mold resistance in winter wheat ( L.).

Breed Sci 2020 Apr 29;70(2):246-252. Epub 2020 Feb 29.

Department of Plant Pathology, Washington State University, Pullman, WA, 99164, USA.

Speckled snow mold caused by is one of the most devastating diseases of winter wheat in Hokkaido, Japan and parts of the Pacific Northwest region of USA. Münstertaler is a winter wheat landrace from Switzerland that has very high resistance to snow mold and superior freezing tolerance. Quantitative trait loci (QTL) for resistance to speckled snow mold were identified in a doubled haploid population derived from a cross between Münstertaler and susceptible variety Ibis, both under field conditions and controlled environment tests.

Identification and epistasis analysis of quantitative trait loci for zeaxanthin concentration in maize kernel across different generations and environments.

Breed Sci 2020 Apr 26;70(2):212-220. Epub 2020 Feb 26.

Maize Research Institute, College of Agronomy and Biotechnology, Southwest University, Chongqing 400716, China.

Zeaxanthin, a natural fat-soluble pigment, not only increases plant resistance, but also has vital significance for human health. However, quantitative trait loci (QTL) and the epistatic effects of zeaxanthin concentration in maize kernel have not been well studied. To identify QTLs and analyse the epistatic effects of zeaxanthin concentration in maize kernel, two sets of segregating generations derived from the cross between HuangC (a high zeaxanthin concentration inbred line) and Rezi1 (a low zeaxanthin concentration inbred line) were evaluated in three different environments.

Hokkaido Agricultural Research Center, National Agricultural Research Organization, Sapporo, Hokkaido 062-8555, Japan.

The optimization of heading date is a key aspect for maximizing grain productivity in cereal crops including rice. The combinations of genes for heading date, a quantitative trait, are a major driver in the wide adaptability of cultivated rice worldwide. Here, we identified a novel QTL, (quantitative trait locus for days-to-heading on chromosome 3), for early flowering time in the F population derived from a cross between Hoshinoyume (HS) and Daichinohoshi (DH) among local rice populations with extremely early heading date.

National Institute for Plant Biotechnology, LBS Building, Pusa Campus, New Delhi 110012, India.

Rice is a food crop of global importance, cultivated in diverse agro-climatic zones of the world. However, in the process of domestication many beneficial alleles have been eroded from the gene pool of the rice cultivated globally and eventually has made it vulnerable to a plethora of stresses. In contrast, the wild relatives of rice, despite being agronomically inferior, have inherited a potential of surviving in a range of geographical habitats. Read More

Graduate School of Life and Environmental Sciences, University of Tsukuba, 1-1-1 Tennodai, Tsukuba, Ibaraki 305-8572, Japan.

Ecotype breeding is a key technology in common buckwheat ( Moench) for the breeding of highly adaptive cultivars and their introduction to other cultivation areas. However, the details of the relationship between photoperiod sensitivity and ecotype remain unclear. Here, we evaluated photoperiod sensitivity in 15 landraces from different parts of Japan, and analyzed quantitative trait loci (QTLs) for photoperiod sensitivity using two F segregating populations derived from the crosses between self-compatible lines ('Kyukei SC2' or 'Buckwheat Norin PL1', early days-to-flowering) and allogamous plants (intermediate or late days-to-flowering).

Common buckwheat is recognized as a healthy food because its seed contains large amounts of protein, minerals, and rutin. However, the yielding ability of common buckwheat is lower than that of other major crops. The short growing period, moisture injury, occurrence of sterile seeds due to lack of flower-visiting insects, and yield loss due to lodging and shattering cause low and unstable grain yield.

Buckwheat heteromorphic self-incompatibility: genetics, genomics and application to breeding.

Breed Sci 2020 Mar 30;70(1):32-38. Epub 2020 Jan 30.

Graduate School of Agriculture, Kyoto University, Sakyou-ku, Kyoto 606-8502, Japan.

Common buckwheat ( Moench 2 = 2 = 16) is an outcrossing crop with heteromorphic self-incompatibility due to its distylous flowers, called pin and thrum. In pin plants, a long style is combined with short stamens and small pollen grains; in thrum plants, a short style is combined with long stamens and large pollen grains. Both the intra-morph self-incompatibility and flower morphology are controlled by a single genetic locus named the locus; thrum plants are heterozygous () and pin plants are homozygous recessive () at this locus.

Breed Sci 2019 Dec 24;69(4):651-657. Epub 2019 Oct 24.

Laboratory of Plant Molecular Genetics and Breeding, Southwest University of Science and Technology, 59 Qinglong Road, Mianyang 621010, China.

Seedling vigor is of vital importance for the initial plant establishment of direct-seeded rice. Here, 166 recombinant inbred lines were employed to assess eight seedling vigor traits over the first 25 days of germination. Significant correlations were found between most traits, and statistical analysis has revealed, for the first time, a linear relationship that uses seedling height and fresh weight to accurately predict the accumulation of dry biomass.

Comparative QTL analysis for yield components and morphological traits in maize ( L.) under water-stressed and well-watered conditions.

Breed Sci 2019 Dec 31;69(4):621-632. Epub 2019 Oct 31.

Drought significantly influences maize morphology and yield potential. The elucidation of the genetic mechanisms of yield components and morphological traits, and tightly linked molecular markers under drought stress are thus of great importance in marker assisted selection (MAS) breeding. Here, we identified 32 QTLs for grain weight per ear, kernel ratio, and ear height-to-plant height ratio across two F populations under both drought and non-drought conditions by single-environment mapping with composite interval mapping (CIM), of which 21 QTLs were mapped under water-stressed conditions.

Genetic mapping is a basic tool for eukaryotic genomic research. It allows the localization of genes or quantitative trait loci (QTLs) and map-based cloning. In this study, we constructed a linkage map based on DNA samples from a commercial strain L808, including two parental monokaryons and 93 single spore isolates considered with segregating to 1:1:1:1 at four mating types (AB, AB, AB and AB).

Faculty of Agriculture, Saga University, 1 Honjo-machi, Saga, Saga 840-8502, Japan.

Isoflavones in soybean seeds are responsible for plant-microbe interactions and defend against pathogens, and are also beneficial to human health. We used two biparental populations and mini core collection of soybean germplasm to identify and validate QTLs underlying the content of isoflavone components. We identified a major QTL, , which regulates the content of malonylglycitin, on chromosome Gm11, in populations bred from parents with high, low, and null glycitein contents. Read More

Climatic changes and potatoes: How can we cope with the abiotic stresses?

Tsukuba-Plant Innovation Research Center, University of Tsukuba, 1-1-1 Tennodai, Tsukuba, Ibaraki 305-8572, Japan.

Climate change triggers increases in temperature, drought, and/or salinity that threaten potato production, because they necessitate specific amounts and quality of water, meanwhile lower temperatures generally support stable crop yields. Various cultivation techniques have been developed to reduce the negative effects of drought, heat and/or salinity stresses on potato. Developing innovative varieties with relevant tolerance to abiotic stress is absolutely necessary to guarantee competitive production under sub-optimal environments. Read More

Common cutworm (CCW) is a serious herbivorous insect pest of soybean. Previously, we conducted an antixenosis bioassay (measuring feeding preference) with CCW using recombinant inbred lines (RILs) derived from a cross between a wild soybean () collected in Hiroshima prefecture (JP110755) and the leading cultivar, Fukuyutaka. The analysis revealed quantitative trait loci (QTLs) for antixenosis resistance, and . Read More
