Genetic variability for yield and yield components in Jerusalem artichoke (Helianthus tuberosus L.)

Abstract

and Aleksići. The trial was arranged in a randomized complete block design with three replications. The following parameters were analyzed: tuber weight (g), plant height (cm), stem number/plant, average stem thickness (cm), green mass yield/plant (kg), and dry mass yield/plant (kg). Average tuber weight ranged from 36.7 g (Bosna) to 61.0 g (Lazarevo). Plant height ranged from 1.55 m (Lazarevo) to 2.20 m (Aleksići). Stem number/plant varied from 2.2 (Aleksici) to 5.3 (Modrica). Stem thicknesswas between 1.24 cm (Bosna) and 2.11 cm (Aleksići). The population Bosna had the lowest average yield of green mass and dry mass yield/plant, while the highest mean value had population Aleksići. Broad sense heritability varied from 34.66% (plant height) to 50.99% (dry mass yield/plant). Highly significant positive correlations between plant height and stem thickness (r = 0.874), stem thickness and green mass yield (r = 0.919), stem thickness and dry mass yield (r = 0.902) were established. Jerusalem artichoke populations were clustered into two groups, and the first group was composed of two subgroups .The results of these studies will allow choice of Jerusalem 46

The Effects of Potassium Fertilization and Irrigation on the Yield and Health Status of Jerusalem Artichoke (Helianthus tuberosus L.)

“…Jerusalem artichoke (JA) has been long grown as a source of animal feed, but in recent years, its popularity increased in the food processing industry, mainly in the production of functional ingredients such as inulin, oligofructose, and fructose [1][2][3][4]. The leaves and stems of JA are also a source of bioactive compounds that are used in the treatment of wounds and swelling [5][6][7].…”

Discovering Penicillium polonicum with High-Lytic Capacity on Helianthus tuberosus Tubers: Oil-Based Preservation for Mold Management

“…Carbohydrates, inulin, and protein contents varied during storage according to the treatments, both oils minimized the development of the deterioration process. A fresh JA tuber contains up to 80% water, 10.6–17.3% carbohydrates—mainly in the form of inulin (7–30%)—and about 2–8% protein [ 6 , 7 , 65 ]. However, these contents vary due to several reasons, such as variety, climatic changes, and storage conditions.…”

“…Jerusalem artichoke ( Helianthus tuberosus L. family: Asteraceae ) is a tuber-producing plant. In addition to being used as livestock fodder and in the production of biofuels, its tubers are consumed in human food and some functional-food ingredients because of their high nutritive value and polysaccharides contents, such as inulin, and oligofructose [ 6 , 7 ]. Under storage conditions, several fungi associated with rotted JA tubers have been reported, which vary in their disease potentiality and economic significance, e.g., Sclerotium rolfsii , Sclerotinia sclerotiorum [ 8 , 9 , 10 ], Botrytis cinerea , Rhizopus stolonifera , Penicillium, and Fusarium species [ 11 ], and Rhizoctonia solani [ 12 ].…”

Jerusalem Artichoke (Helianthus tuberosus L.): A Versatile and Sustainable Crop for Renewable Energy Production in Europe

“…There is a vast number of JA accessions held in world germplasm repositories, totaling to more than 1100 by 2006 (reviewed in [2]) and increasing, as new collections are being gathered (e.g., [30,64]). There is, however, an urgent need for correct clone identification and classification in genetically similar clusters, to enhance conservation and facilitate breeders in choosing cross-compatible parental clones with high probability of giving superior progenies [2].…”
