Screening for PVYN-Wi Resistance in Kenyan Potato Cultivars

چکیده

Abstract Over the past decades, two new strains of potato virus Y (PVY N-Wi (Wilga) and PVY NTN ) have been most widely distributed worldwide in crops ( Solanum tuberosum L.). Effective resistance genes comprehensive against all known are available some commercial cultivars. However, not cultivars challenged by to confirm effectiveness resistances available. This study was set identify resistant genotypes estimate yield losses Kenya. used for screening because it prevalent strain Kenya also found produce more severe infection Kenyan compared with O (the second strain). Three cultivars, Karibu, Sherekea Unica, were identified as they did get infections over three seasons both greenhouse field experiments. In addition, early generation breeding clones at 28 days post-inoculation. susceptible Dutch Robyjn, Nyayo Mpya, caused 21.6, 39.0 53.1%, respectively, after seasons. demonstrated necessity screen based on make an informed decision usefulness current levels

Potato cultivars from the mexican national program: sources and durability of resistance against late blight.

ABSTRACT The Mexican National Potato Program has produced several cultivars with high levels of field resistance. We evaluated the durability of resistance to potato late blight of a selection of 12 such cultivars using data from 1960 to the present. Data were extracted from the field notebooks located in the archives of the Mexican National Potato Program in the John S. Niederhauser Library in...

In vitro microtuberization in potato (Solanum tuberosum L.) cultivars.

Mechanism of microtuberization in three elite cultivars kufri badhsha (KB), kufri chandramukhi (KCM) and kufri jawahar (KJ) of potato was studied. Sprouts of all the three cultivars were used to obtain in vitro shoot cultures. MS medium supplemented with chlorocholine chloride was found to be most suitable for all the cultivars. Maximum tuberization was obtained under incubation conditions of c...
