Screening of Solanum melongena Against Leucinodes orbonalis Guenee 12+

🔖 Master's Thesis from the year 2012 in the subject Biology - Zoology, grade: A, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu (SKUAST-K, srinager), course: Agriculture, language: English, abstract: The present investigations were carried out to screen some important varieties/genotypes of brinjal against Leucinodes orbonalis under field conditions and also to determine morphological, biochemical characteristics of brinjal showing some degree of tolerance against this pest. All 12 varieties/genotypes as treatment were raised in Randomized Block Design with 3 replications. The relative susceptibility of the various brinjal genotypes to Leucinodes orbonalis infestation was ascertained by recording number, weight of infested and uninfested fruits. Relative susceptibility of shoots was done by recording number of damaged/undamaged shoots from each entry up to harvest time and percentage calculated. Observations in respect of several morphological characters including fruit length, fruit diameter, shape and volume index, length of peripheral seed ring, ratio of length of peripheral seed ring, length of seed less area, ratio of length of seed less area, pericarp thickness, shoot/leaf hairs, yield per plant, number of fruits per plant, plant height, number of branches per plant, roughness/smoothness of calyx, flower and fruit colour and biochemical characters including total phenols, total sugars, moisture and ash were assayed. Correlation between bore...
