Abstract

The problem in the development of wheat crops today is climate change that reduces wheat production in almost all regions of the world. It has an impact on rising temperatures and limited water supplies that can cause drought stress. These problems became the main issue of world wheat crop development. Therefore, the assembly of adapted varieties of wheat that adapted to climate change is crucial. This study aims to evaluate characters and select wheat lines based on the yield and yield component characters and to obtain tolerant wheat lines under those natural stress in tropical environments. The study used 56 wheat lines and 6 released varieties for controls, 3 replications with Randomized Block Design. Character evaluation shows significant differences in a large number of observational characters except for the number of seeds/spike and moisture content. Characters that can be used for selection and evaluation of promising lines are all characteristics of the yield and yield components except the Number of Seed Per spike (NSS) and Water Content (WC) characters. Promising lines were G5, G8 and G11 became potential selection lines with potential yields of 3, 3.39 and 3.03.
