colonies was white to gray, and the reverse was colored pale yellowish brown. The strain produced no reproductive structures even on sterilized natural substrates. The absence of morphological characteristics implied that this fungus could be treated as a deuteromycete in the Agonomycetes3). YM-170320 (1) was produced by solid state fermentation. Vegetative mycelia of strain YL-03706F growing o...

A four-year rotation is desirable for potatoes. Proper rotation of crops is one necessary practice for avoiding the holding over of potato diseases in the soil. For potato wilt control at least a four-year rotation should be used. The one shown here makes use of corn, grain, clover, and potatoes. The best basic crop rotation for Western Oregon is grain, clover seed, clover hay, and a cultivated...

this research was performed in order to study and diagnose potato virus y,potyvirus (pvy), potato virus x,potexvirus (pvx), potato virus s,carlavirus (pvs), potato virus a,potyvirus(pva) and potato leafroll luteovirus (plrv) on tubers and leaves of different potato varieties, namely, solea, safran, floris, proventa, milva, universa, lady olympia, vangogh, and marabel grown in afyon region of tu...

A new potato tuber lipoxygenase full-length cDNA sequence (lox1:St:2) has been isolated from potato tubers and used to express in Escherichia coli and characterize a novel recombinant lipoxygenase (potato 13/9-lipoxygenase). Like most plant lipoxygenases it produced carbonyl compounds from linoleate (the preferred substrate) and was purified in the Fe(II) (ferrous) state. Typical of other potat...

Potato (Solanum tuberosum L.) varieties, viz. Kufri Lauvkar (early maturing), Gaurav and Jyoti (medium maturing) were examined during the years 2018–19 2019–20 for seed size tubers production with 3 dates of haulm killing, 70, 80, 90 days after planting under West-Central Indian conditions at ICAR-Central Research Institute, Regional Station Gwalior, Madhya Pradesh. Haulm killing 80 (15.05 t/ha...

Economic theory highlights the critical importance of excludability in encouraging private research and development in the agri-food sector. Without it, private research will languish and social welfare could suffer. Since 1970 governments around the world have recognized this and strengthened the legal protections for biotechnology processes and products (e.g. patents, plant breeders’ rights a...

From 1995 through 2001, genetically modified potatoes were sold in the United States and Canada under the brand name NewLeafTM. These potato varieties were relatively popular with growers because they replaced pest-control practices involving intensive use of pesticides with technology that was present in the potato seed. Market tests indicated that the concept of reduced pesticide use through ...
