ABSTRACT
The experiment was undertaken to evaluate storage behaviour on 22 genotypes and during 90 days of storage period and it revealed that maximum potato losses due to sprouting and rotting were recorded in K. Sadabahar, K-22, PH-3 and PH-2. Only percentage of rottage tubers (early harvested genotype r=0.912 and late harvested genotype r=0.903) was found to be significantly correlated with storage loss with maximum direct effect on it, so for breeding improvement of potato genotypes which showed minimum rottage loss should be considered. To reduce storage in these favourable genotypes combination breeding with K. Suriya, K. Pushkar and K. Himalini may be done as these varieties were least affected due to rotting or sprouting during storage. Genotypes with highest direct effect on total loss due to country storage was exerted by percent of rottage tubers followed by percent of sprouted tubers and it was predominantly found to be determining factor of storage loss.
Key words :
Correlation, Potato genotypes, Rotting tuber, Storage loss, Storage parameters, Sprouting, Tuber characters.
