Abstract | ||||
This investigation was carried out to develop a model for molecular marker-assisted selection (MAS) to identify the promising cultivars that posses tolerance to environmental stresses (i.e. drought and salt) at a very early stage of the breeding program. Four cultivars of sugarcane were used in this study, i.e., 686/20, G95/21, 654/9 and F160. The performance of the four cultivars in sand culture experiment revealed that G.86/20 and G95/2 were superior in their salt and drought tolerance according to their performance in some yield- related traits. Cultivar G54/9 was the third, followed by F160, which was very sensitive to the two stresses. Some molecular genetic markers (SDS protein, esterase and acid phosphatase, isozymes.) were developed for the four cultivars in relation to the two stresses. | ||||
