REACTION OF POTATO VARIETIES/LINES AGAINST (PVY) UNDER NATURAL FILED CONDITIONS AND CONFIRMATION ...

A reduction in potato area and productivity has been documented as a result of a variety of variables, the most important and harmful of which is PVY. This illness can cause yield losses of up to 80%. Because no chemical exists to combat viral plant diseases, the only way to deal with the problem is to generate resistant types through conventional or molecular breeding techniques. For the availability of resistance sources, we investigated locally produced potato lines in natural field circumstances. Twenty-seven lines/varieties were cultivated in natural field settings and tested for the presence or absence of resistance to PVY using an ELISA kit. No line/variety was found to be immune in a field study, which was validated by an ELISA test. PVY resistance was found in four lines/varieties: Lady Rosetta, Crusier, FD 69-1, and FD 35-36, while two lines/varieties were moderately resistant and 21 lines/varieties were severely vulnerable to PVY.
