Screening sugar beet genotypes in drought stress condition using tolerance indices

Abstract

[...]sugar beet breeders could effectively use selected parental lines from this germplasm for further research works like genetic analysis of drought tolerance and hybrid breeding programs. [...]this project was aimed for evaluation of several tolerance indices in screening of studied sugar beet germplasm against drought stress and identification of drought tolerant genotypes of sugar beet based on root and white sugar yield. [...]data from root yield (Figure 1) revealed that genotypes such as G04 "HSF-844", G16 "HSF-859", G18 "HSF-861", G35 "HSF-883" and G41"32434-91" are promising sugar beet genotypes (Group A) which have suitable root yield in both conditions. (2010), the genotypes classification based on cluster analysis was paralleled with output of three dimensional plots. [...]by using genotypes that are located in separate groups and have maximum genetic distance, it is possible to analyze genetic basis of these drought tolerance indices in sugar beet.
