Seleksi Genotipe Gandum Tropis Toleran Suhu Tinggi Menggunakan Marka SSR

Abstract

High temperature stresses is a challenge for developing the wheat in tropical environments and affect each stage of plant development. Therefore, early detection of yield characteristics using high-temperature linked markers is necessary in order to produce adaptive varieties in tropical environments. The purpose of this study was to detect differences in the formation of band patterns from tropical wheat populations from field selection using SSR markers for heat tolerant. This experiment used 10 selected genotypes and tested with 10 SSR markers for heat tolerant. The results showed that from 10 SSR primers only 2 primers showed a difference in band size, namely on the XGWM285 and XBARC197 primers which were formed only in OHP12a1-1-9 genotypes.Keywords : Tropical wheat, Simple sequence repeat (SSR) marker, heat tolerant, Genotypes
