Potato breeding aims to improve crop productivity, quality and resilience based on heritable characteristics. Estimating the trait heritability correlations—both genetic phenotypic—among characteristics in a target population of environments allows us define best method that leads selection gains. Breeding clones (47) released cultivars (209) were grown using simple lattice designs at three tes...

Black truffles that morphologically resemble Tuber indicum have been known to occur in Japan since 1979. Our previous studies showed that there are two phylotypes of these truffles, both of which fell into the T. indicum complex (hereinafter "Tuber sp. 6" and "Tuber sp. 7"). However, their taxonomic treatment is still unclear. In this study, we conducted morphological and phylogenetic analyses ...

UV-B radiation and EOD light (EOD) quality has both signaling and damaging effects based on the dosage and time of exposure. At highland areas UV-B decreases crop productivity and also light quality increase at high elevation area but EOD light quality effect was not researched based on altitude. Therefore, in the present study a field experiment was conducted to investigate the effects of UV-B...

an investigation was carried out to reveal the changes in the concentration of soluble carbohydrates under tuber dormancy in food yam (dioscorea esculenta) tubers and in an economically important spice cum medicinal plant turmeric (curcuma longa) rhizomes under storage. harvested, fully matured tubers of yam and rhizomes of turmeric were stored in wooden boxes under the conditions of 28 ? 2?c t...

life cycle assessment (lca) had proven to be an appropriate assessment tool for analysis of agri-food products by identifying, quantifying and evaluating the resources consumed and emissions released into the environment. this study was performed for evaluation the environmental impacts of potato agroecosystems based on nitrogen levels by using lca methodology. tuber yield mean during 1999-2013...

Abstract To contribute to the development of a novel cropping system for potato grown from greenhouse-derived seedlings hybrid true seeds, planting density trials were carried out under normal Dutch agronomic conditions. For two consecutive years, 5-week-old experimental genotypes transplanted into farmers’ production fields at contrasting locations: flat-bed on sandy soil and traditional ridge...

The chemical composition of the essential oil from PINELLIA TUBER (Japanese name: Hange), the dried rhizome of Pinellia ternata, was investigated by capillary gas chromatography (GC) and GC-mass spectrometry (MS) analyses. The oil obtained from Pinellia tuber was revealed the presence of 114 compounds, representing 90.6% of the total oil identified. This colorless oil had a spicy and woody odor...

The uptake and distribution of Cd in potatoes over the course of a growing season was investigated in two cultivars of potatoes that differed in tuber Cd concentration. Plants were grown in soil with supplemental Cd. The concentrations of Cd in different tissues varied greatly in the order roots>shoots>> tubers. After the initiation of tuber bulking, shoot growth ceased and the increase in tota...

North American isolates of Colletotrichum coccodes, representing six vegetative compatibility groups (NA-VCG), were used to study morphological and pathogenic variability. The objective was to determine if variability in conidial and microsclerotial size was related to pathogenicity. Significant differences were detected in length, width, and length/width ratios of conidia as well as in the len...
