Abstract Common scab, calcium deficiency, and internal tuber defects, such as hollow heart, have severe negative impact on the marketable yield profitability of potato ( Solanum tuberosum L.) farmers. The present study was conducted to detect quantitative trait loci (QTL) controlling these traits. A tetraploid linkage map constructed using 808 single nucleotide polymorphisms (SNPs) from SolCAP ...

Nutrient deficiency is a major constraint for potato ( S olanum t u berosum L.) production in Ethiopia. Potato response to potassium fertilizer declined with widespread deficiencies of nutrients other than N and P, farmers are discouraged apply such recommendations. This study was, therefore, conducted two years (2018-2019) on nitisols under irrigation evaluate the liquid (K) rates. The treatme...

The aim of the study was to evaluate dependence potato crops on level irrigation in three mesoregions Poland. field experiments were carried out 2009–2011 according an obligatory methodology for evaluation crop cultivars. Three factors tested: two cultivation practices (with and without as control), five cultivars, locations (Masłowice, Szczecin-Dąbie, Węgrzce). conducted randomized blocks trip...

We apply polarities, axiallities and the notion of entropy to the task of identifying marketable items and the customers that should be approached in a marketing campaign. An algorithm that computes the criteria for identifying marketable items and the corresponding experimental work is also included.

Germplasm of Solanum tuberosum and Solanum phureja exhibit a wide (over 20-fold) variation in tuber carotenoid content. The levels of carotenoids during tuber development and storage were compared in a high carotenoid-accumulating S. phureja accession (DB375\1) with two S. tuberosum cultivars (Pentland Javelin and Desiree) that accumulate lower levels of tuber carotenoid. On a dry weight basis,...

The potato tuber moth, Phthorimaea operculella (Zeller), in tropical and subtropical countries, is the most destructive pest of potato, Solanum tuberosum L. The larvae attack foliage and tubers in the field and in storage. The purpose of this study was to evaluate the efficacy of a Bt-cry5 transgene to control the potato tuber moth in tuber tissues. Tuber bioassays using stored (11-12 mo old) a...

Field experiments were conducted at Ebonyi State University, Faculty of Agriculture Research Farm Abakaliki, Nigeria during 2009/10 growing seasons to evaluate the effects of staking and planting dates on the grain/tuber yields of seven accessions of African yam bean (Sphenostylis stenocarpa, Hochst. Ex. A. Rich). The results indicated that all the African yam bean accessions performed better w...

We screened the pharmacological effects of a 50% ethanol extract of Yacon tubers and leaves on spermatogenesis in rats. As a result, we found that Yacon tuber extracts increased sperm number and serum testosterone level in rats. It has been reported that the crude extract of Yacon tubers and leaves contain phenolic acids, such as, chlorogenic acid, ferulic acid and caffeic acid by HPLC/MS analy...
