Summary
Tuber yield, dry matter and true protein content were studied in 24 andigena potato genotypes. Their performance and response differed greatly and significantly when grown at three levels of inorganic N, P and K fertilizer application. In general, tuber yield and protein content increased with increased fertilizer level, whereas dry matter content initially decreased but then increased significantly with fertilizer additions. For all three characteristics, genotype x fertilizer interaction was significant, and although there was a wide genetic variability for relative responsiveness of different genotypes, no significant undesirable association was detected for performance. The genotypes JEX/A 674, 706 and 744 are most promising and could be used for wide-scale cultivation and for breeding.
