Abstract
The genotype Parbhani Kranti recorded maximum moisture content of 90.33 % which was at par with IC-113904 (89.77 %) and IC-43746 (89.56 %) whereas the resistant genotype IC 90210 recorded a minimum moisture content of 81.16 %. This shows that moisture content was ranged from 81.16 to 90.33 %. The chlorophyll content in selected okra genotypes was ranged from 0.18 to 0.52 mg/gm. Significant chlorophyll content of 0.52 mg/gm was noticed in the genotype EC 128888 as against minimum chlorophyll content of 0.18 mg/gm in the genotype 1557. The results indicated that there was no relation between amount of chlorophyll content in fruits of selected okra genotypes and E. vittella infestation. Results also indicated that, resistant genotypes contain maximum amount of total phenol as compared to susceptible and moderately susceptible genotypes. Maximum total phenol content of 1.27 and 1.17 % was recorded in the two resistant genotype i.e. IC 90210 and IC-974 respectively. However two genotypes from susceptible and four genotypes from moderately susceptible category i.e. IC-99724, 1557, IC-90251, IC-133336, Parbhani Kranti and 1957 recorded minimum of 0.59, 0.60, 0.61, 0.65, 0.68 and 0.69 % total phenol content respectively. The total soluble sugar content was ranged from 1.98 to 5.91 %. Moreover, it was noticed that, susceptible genotypes i.e. 1557 and Parbhani Kranti contained maximum total soluble sugar of 5.91 and 5.84 % respectively as against minimum of 1.98 per cent and 2.13 % total soluble sugar in resistant genotypes i.e. IC-90210 and IC-974 respectively. Ash content in the tested genotypes was varied from 1.47 to 4.64%. Least ash recorded was of 1.47 % which is in the genotype Parbhani Kranti which was at par with the genotypes 1557 and IC-90251 with 1.61 and 1.73% ash respectively. However, maximum ash content of 4.64 % was noticed in the genotype IC-974. The results showed that the genotypes with minimum ash content were found to be susceptible to E. vittella infestation whereas the genotypes with maximum ash content were found to be resistant to E. vittella infestation.
