DNA extraction in many plants is difficult because of metabolites that interfere with DNA isolation procedures and subsequent applications, such as DNA restriction, amplification and cloning. We have developed a reliable and efficient method for isolating genomic DNA free from polysaccharide, polyphenols and protein contaminants from tropical tuber crops (Elephant foot yam, Cassava, Sweet potat...

In the Mediterranean Basin, potato (Solanum tuberosum L.) is a major staple crop, yield performance of which can vary dramatically based on pedo-climatic conditions and genotype. Hence, dissecting genotype × environment interaction (GEI) in this region mandatory for setup high-yielding stable genotypes, also considering its importance local breeding development protected geographical identifica...

ABSTRACT- The influence of foliar application of urea, humic acid (HA), Zinc (Zn), and Boron (B) on potato yield (CV. Cror) was studied in a field experiment during 2010-2012 at the research farm of Nuclear Institute for Food and Agriculture (NIFA). Treatments consisted of i) Control, ii) Nitrogen-Phosphorous-potassium (NPK) (250,150,250 kg ha-1) , iii) NPK (125,75,125 kg ha-1) with 0.03% HA, i...

Coping with water shortages without compromising tuber yield is a majorchallenge for potato (Solanum tuberosum L.) production in northern China. In thisstudy, we used three potato cultivars with different sensitivities to drought toevaluate the effect of long-term drought stress on morphological and physiologicalcharacteristics under field conditions during three growing seasons (2009-2011).Our...

The aim of the study conducted in 2019-2021 was to determine effect biostimulants and growth regulators on yield size structure, as well chemical composition edible potato tubers. cultivar evaluated Vineta. Asahi SL, Kelpak Aminoplant, Tytanit, gibberellic acid (GA3) Moddus 250 EC were applied cultivation. application SL Tytanit increased total marketable tuber yield, average weight. Aminoplant...

The effects of row proportions and nutrient management was studied in potato (Solanum tubersoum L.) + Indian mustard [Brassica juncea (L.) Czernj.] intercropping system during 2014–15 2015–16 at Amar Singh College Farm, Lakhaoti (Bulandshahr), Uttar Pradesh. field experiment laid out a split-split plot design with 3 replications. main treatments consisted varieties, viz. ‘Kufri Pukhraj’, Anand’...

This experiment was carried out during the two growing seasons 2012/2013 and 2013/2014 at the experimental farm of Unit for Strawberry and Non Traditional Horticulture Crops, Horticulture Department, Faculty of Agriculture, Ain Shams University, Egypt, in order to investigate the effect of magnetic field on germination of true potato seeds (TPS), vegetative growth and potato tubers characterist...

The study was initiated to generate genetic information on important yield contributing characters of sweet potato genotypes maintained in Chhattisgarh. Twenty eight potatoes (Ipomea batatas L.)  were evaluated estimate the variability for different characters. experiment conducted using a Randomized Complete Block Design with three replications. parameters studied. Analysis variance showe...

The cultivar selection and nitrogen (N) fertilization are key management factors to improve potato yield. aim of the present study was evaluate ecophysiological determinants biomass tuber yield in genotypes response N availability under field conditions. Experiments 1 2 were carried out a volcanic soil southern Chile during 2021–2022 season. Treatments applied factorial combination (i) fifteen ...
