The Ralstonia solanacearum species complex (RSSC) is a highly diverse cluster of bacterial strains found worldwide, many of which are destructive and cause bacterial wilt (BW) in a wide range of host plants. In 2009, potato production in Madagascar was dramatically affected by several BW epidemics. Controlling this disease is critical for Malagasy potato producers. The first important step towa...

Abstract Conversion of potato from a tetraploid, heterozygous, vegetatively propagated crop to diploid F1 hybrid, via botanical seed, would constitute considerable advance for global agriculture, but faces multiple challenges. One such challenge is the difficulty in inbreeding potato, which involves purging deleterious alleles its genome. This commentary discusses possible reasons this and high...

Potato is a major staple food crops in the hilly region of Nepal.

Experiments were conducted to study the plant growth and tuber yield of the seed potato collected from PVY and PLRV infected plants. The seed potatoes were graded as under size (<28 mm), A grade ( 28-40 mm), B grade (41-55 mm) and over size (>55 mm) which were planted following RCBD in the field. Third generation seed potatoes of Diamant variety were used. The incidence of viruses was confirmed...

strategies based on genotypic selection. It is concerned with producing improved cultivars for clonal propagation by tubers, and not with ones for propagation by True Potato Seed (TPS). This is because SCRI breeders are sceptical about the place of TPS in the highly developed markets of Europe and North America, whilst acknowledging that there is much interest throughout the tropics in TPS as a...
