knowledge of traits associated with drought tolerance would be useful for developing breeding materials fortarget environments. to study these traits, 119 spring durum wheat breeding lines (bls) from the international maize and wheat improvement center (cimmyt) were evaluated along with local checks (one modern cultivar and three landraces) in three experiments under terminal and non-terminal d...

Doubled haploid (DH) technology has been used in breeding programs for several decades and is currently the method of choice in a number of crop species, including barley (Hordeum vulgare L.), rapeseed (Brassica napus L.), maize (Zea mays L.), and wheat (Triticum aestivum L.). In this study we investigated via computer simulation the benefit of using DHs compared with the conventional wheat bre...

the first step in breeding programs is detecting the genetic diversity in breeding materials. molecular markers help to reduce costs and time in breeding programs. genetic variation in 49 genotypes of tobacco were studied using 12 issr markers, 3 retrotransposon markers and the combination of issr and retrotransposons. one hundred forty seven polymorphic bands were produced using 16 primers. to...
