An investigation was carried out at Vegetable Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar during spring-summer season 2011 and 2012 to study the genetic diversity using Mahalanobis’s D2 – technique among thirty five potato (Solanum tuberosum L.) germplasm for important yield attributing and quality traits. The D2 values were calculated and thirty five potato genotypes were grouped into nine clusters for growth characters and ten clusters for quality traits respectively. All the genotypes included in the present investigation, were indigenous, but their grouping in different clusters, suggested that genotypes did not follow the geographic distribution. The cluster I contained the maximum number of genotypes with respect to both yield attributing and quality traits. The inter cluster distance in most of the cases were higher than the intra-cluster distance indicating wider genetic diversity among the genotypes of different groups. Average tuber weight of potato plant contributed maximum (31.76%), followed by number of tuber per plant (27.56%), internodal length (14.45%) and plant dry matter content (13.61%) for growth characters. For quality characters, ascorbic acid content (24.70%), protein content of tuber (20.84%) and TSS of tuber (20.00%) contributed effectively towards genetic divergence. So, these traits will offer a good scope for improvement of yield and quality through rational selection of parental genotypes for future potato breeding. The findings indicated that use of parents selected from the same cross or from a cross involving a common parent should be avoided in hybridization. The results broadly showed there was no parallelism between geographical and genetic divergence.

The effect of endophytic Bacillus subtilis (strains 10-4, 26D) and their compositions with salicylic acid (SA) on some resistance and quality traits of stored potatoes infected with Fusarium dry rot were studied. The experiments were carried out on hydroponically grown Solanum tuberosum L. tubers that were infected before storage with Fusarium oxysporum and coated with B. subtilis 10-4, 26D with and without exogenous SA, and then stored for six months. It has been shown that 10-4, 26D, 10-4 + SA, and 26D + SA reduced in different levels (up to 30–50%) the incidence of F. oxysporum-caused dry rot (with the highest effect for 10-4 + SA). SA notably enhanced the positive effect of 10-4, while for 26D, such an effect was not observed. All of the tested treatments increased amylase (AMY) and AMY inhibitors activity in infected tubers, while decreased Fusarium-induced protease activity (except in the case of 10-4 + SA, which promoted a slight increase) was revealed. 10-4, 26D, and their compositions with SA decreased (in different degrees) the pathogen-caused lipid peroxidation, proline, and reducing sugars accumulation in potatoes after long-term storage. It was also discovered 10-4 and 26D, regardless of SA presence, decrease pathogen-induced glycoalkaloids α-Solanine and α-Chaconine accumulation and preserved increased levels of starch and total dry matter in infected stored potatoes. The findings indicate endophytic B. subtilis and its compositions with SA is a promising eco-friendly and bio-safe approach to cope with postharvest decays of potato during long-term storage; however, when developing preparations-compositions it should take into account the strain-dependent manner of B. subtilis action together with SA.
