Given the importance of potato in the economy and people’s nutrition, as well as planting of disease-free seeds, it seems necessary to produce healthy seeds through tissue culture. This study was conducted during 2012-2013 at the Research Center of Agricultural University of Tajikistan aiming to evaluate the effect of different sizes of mini-tuber on yield and yield components of potato crop. A...

Drosophila mojavensis adults, which breed and feed on necrotic cacti, show an increase in longevity when exposed to atmospheric ethanol. The increase in longevity is accompanied by retention of mature ovarioles and is independent of diet. Differences in longevity among strains from different localities were detected for females. Strains from Arizona and Sonora, Mexico, showed the greatest incre...

Verticillium wilt of potato is a major limiting factor in potato production caused by Verticillium dahliae. The objective of this study was to evaluate the efficacy two elicitors including Acibenzolar-S-methyl (ASM) and Chitosan as plant activator in controlling of potato verticillium wilt in vitro and greenhouse conditions. ASM and chitosan were tested in vitro using Potato dextrose Agar (PDA)...

The phenotypic diversity of potato, Solanum tuberosum was assessed using morphological traits. To verify, how this diversity is distributed among the main potato varieties in the growing areas in Iran. A total of eleven potato varieties, Ramose, Sante, Shepody, Marfona, Maradona, Milova, Santana, Boren, Cosima, Granola and Agria, were evaluated under vivo and situ experimental conditions in Isf...

High frequencies of the fast allele of alcohol dehydrogenase-2 (Adh-2F) are found in populations of Drosophila mojavensis that inhabit the Baja California peninsula (race BII) whereas the slow allele (Adh-2S) predominates at most other localities within the species' geographic range. Race BII flies utilize necrotic tissue of pitaya agria cactus (Stenocereus gummosus) which contains high levels ...
