棉花是重要的工业原材料和天然纤维材料,相比于其他作物,陆地棉的遗传多样性极低,解析其形成原因,对棉花的遗传改良具有重要意义。研究人员通过对两种不同基因型的陆地棉进行全基因组比较分析,发现A08染色体上存在着大片段的遗传变异。该倒位能够将已发表的陆地棉核心种质资源材料分为两类,与利用SNP基因型重构的进化树的分类和主成分分析结果高度一致,表明陆地棉种内可能产生了分化。利用人工创制的群体和陆地棉核心种...
上个世纪90年代,北美灌木柳育种计划在纽约州启动,经过30多年的杂交、选育以及在美国中、北部的区域试验,选育了一大批高产、高抗的灌木柳栽培品种,目前很多品种在美国已商品化生产。在北美纽约州、宾夕法尼亚州等地,灌木柳被广泛用于工业污染地、垃圾填埋场的植物修复、公路防风雪篱以及生物质能源生产。尽管国际上在柳树重金属污染修复方面做了大量研究,筛选出很多对重金属具有高积累、耐性以及转移的品种,但是重金属积...
Bacterial blight (BB) is an important constraint on achieving a high and stable rice grain yield. An increasing number of BB resistance (R) genes have been identified and cloned to increase the availa...
Flavoalkaloids have been found from tea. However, there is limited information about their content in difffferent teas. Herein, 51 tea samples were screened for flflavoalkaloid content. Twelve teas wi...
Eight minor and neglected cultivars of Vitis vinifera L. were characterised according to their ampelographic and agronomic traits and discriminated by molecular analysis with SSR markers. These resul...
In this study the texture profile, total soluble solids (TSS) and the fruit skin colour of four day-neutral strawberry cultivars cultivated in Italy (‘Anabelle’, ‘Murano*’, ‘Portola*’ and ‘Triumph’) ...
Fifteen apple cultivars registered in the Czech Republic were included in this comparative study. The most productive after eight years of cropping was ‘Rucla’, which had a mean yield of 50.9 t/ha. T...
In Hungary the black locust (Robinia pseudoacacia Linnaeus) is one of the most important exotic stand-forming tree species growing mostly under unfavourable ecological conditions. Considering the cli...
An experiment was established in the spring of 2006 in the Experimental Orchard in Dąbrowice (central Poland). The plum cultivars under assessment included: ‘Avalon’, ‘Edda’, ‘Excalibur’, ‘Jubil...
This study was conducted in order to determine the antioxidant activities of certain apple varieties. ‘Galaxy Gala’, ‘Scarlet Spur’, ‘Fuji’, ‘Pink Lady’ and ‘Granny Smith’ were characterized in this ...
Cultivation of apples is currently based on a limited number of commercial cultivars; as a consequence, ancient and local varieties have almost completely disappeared. Red-fleshed, ancient and commerc...
The evaluation of dormancy break based on the number of flower buds in bloom was performed in years 2011–2013 (January–April) for 15 peach cultivars compared to the control cv. Redhaven. Based on the ...
Over the course of 2007–2013, 19 selected cultivars of Chrysanthemum × grandiflorum were tested. Testing was conducted during two seasons under field conditions and on potted plants in the freezing ch...
Hungary lies near the northern border of the apricot growing area, so frost hardiness is a decisive factor for the reliability of production. Both the development and loss of frost hardiness take plac...
Maximum aphid numbers on wheat are positively related to the length of the period elapsed from immigration to the population peak. We predicted that maximum abundances on late maturing cultivars would...
