This is a comprehensive language preview which includes the title, table of contents, objectives and key themes, chapter summaries, and key words for a research document likely related to the study of brinjal crop resistance to pests.
The study objectives include: 1) Studying the incidence and severity of important brinjal varieties/genotypes against shoot and fruit borer under field conditions. 2) Determining the morphological/biochemical characteristics responsible for exhibiting resistance to brinjal shoot and fruit borer (L. orbonalis) by screening various varieties.
The key themes revolve around host plant resistance in brinjal, focusing on morphological and biochemical factors influencing resistance to Leucinodes orbonalis (shoot and fruit borer). It explores the correlation between plant characteristics, infestation levels, and identifies resistant and susceptible genotypes.
The document discusses morphological characters like fruit length, fruit diameter, shape index, volume index, peripheral seed ring length, ratio of the seed ring length, length of seedless area, ratio of length of seedless area, pericarp thickness, shoot and leaf hairs, plant height, number of branches per plant, roughness/smoothness of calyx, and flower and fruit colour.
The study analyzes biochemical parameters including total phenols, total sugars, moisture content, and ash content in relation to borer infestation.
Data is analyzed using Analysis of Variance (ANOVA) and simple correlation to determine relationships between plant characteristics and pest infestation.
The literature review focuses on studies related to the incidence and severity of brinjal varieties/genotypes against shoot and fruit borer under field conditions, and the determination of morphological and biochemical characteristics of brinjal varieties/genotypes exhibiting some degree of tolerance against the brinjal shoot and fruit borer (Leucinodes orbonalis Guenee).
The key words include Brinjal, Screening, Shoot borer, Fruit borer, Incidence, Morphology, and Biochemical parameters.
Specifically mentioned are Brinjal-85 and Local Long (resistant), Shalimar Brinjal Hybrid-1 and Shalimar Brinjal Hybrid-2 (susceptible), as well as several other genotypes classified as tolerant or fairly resistant.
Findings indicate that no brinjal genotype is completely immune to L. orbonalis. Variations in morphological and biochemical characteristics influence susceptibility, with resistant genotypes generally exhibiting traits like higher phenol content and lower sugar content. Infestation is positively correlated with fruit diameter and length of seedless area and negatively correlated with ratio of seedless length and shoot hairs and leaf hairs
