Abstract

ABSTRACT: The aim of this study is to determine some fruit characteristics of 19 different lines hybridized by previous regular studies. These lines were examined in order to determine the differences among volatile components and reveal the differences in comparison with the parents. Plant height (cm), fruit weight (g), fruit width (mm), fruit length (mm), fruit flesh thickness (mm), pungency, immature fruit color and mature fruit color were determined of parents and F4 lines. As a result, a wide range of variations were determined between lines and parents in terms of all parameters apart from pungency. Especially in terms of volatile components, it has been found that some active substances are found only in the father and white genotype (Fenchol, spathulenol and geranyl acetate), some of them only in the mother and orange genotype (α-terpineol, dihexyl azelate and 2-hexadecanol). It was concluded that volatile compounds of the species can be used as a marker for breeding studies.

Highlights

As a widely consumed popular vegetable in the world and in our country, pepper is rich in vitamins and minerals and beneficial for human nutrition
It was determined that the lines selected in terms of fruit characteristics and chemical components have very different characteristics from the parents

Summary

Introduction

As a widely consumed popular vegetable in the world and in our country, pepper is rich in vitamins and minerals and beneficial for human nutrition. 36 771 482 tons of fresh peppers are produced in 1 990 423 hectares in the world. The Capsicum genera (ESHBAUGH, 2012; CARRIZO GARCIA et al, 2016) consist of 43 species with 5 of them newly discovered species (BARBOZA et al, 2019; BARBOZA et al, 2020; MAVI, 2020). Among these species, 5 of them, C. annuum L., C. frutescens L., C. baccatum L., C. chinense Jacq. Exotic pepper varieties being not studied widely have been of interest to breeders in recent years
