GREEN PEPPER GERMPLASM SELECTION FOR IMPROVED PRODUCTION UNDER HEAT AND DROUGHT STRESS CONDITIONS

摘要

A bulk collection of green pepper (Capsicum annuum L.) land variety from southern Egypt was evaluated under heat and drought stress conditions Higher percentage of fruit set was positively associated with increased number of finks, fruit weight and fruit yield while negatively associated with plant height. Elite individual plants were visually selected and their selfed progenies were tested. Parent-offspring regression suggested that non-heritable genetic components of variation had a considerable influence on the expression of percent fiuit set, average fruit weight, number of fruits/plant and fiuit yield/plant. Population raised using bulked S_2 seeds of two most elite tested progenies showed significant increase in these traits compared with population of the original land variety collection. This developed germplasm selection may be useful for stress breeding and physiology investigations in pepper.
