Agronomic performance of potato population B3C2 genotypes in southwestern Uganda
Abstract
104 words
Thirteen potato genotypes known as population B3C2 were
evaluated for yield and resistance to late blight. Assessment of
late blight severity started at the onset of the disease symptoms;
disease severity rating was based on visual symptoms, using a
1-9 CIP scale and percentage leaf area affected. Two genotypes
(391046.14 and 396031.119) showed higher levels of
susceptibility to late blight than Victoria, while two others
(396026.103 and 393280.82) showed higher resistance than
Cruza. Four genotypes, i.e., 396026.103 (38.6 t ha-1),
396031.108 (38.5 t ha-1), 396029.250 (34.5 t ha-1), 396038.107
(31.3 t ha-1) yielded higher than Victoria (61.5t ha-1), the main
commercial cultivar in Uganda.
