Abstract: The chlorophyll content and corticoid content of Chinese Spring(CS)-Synthetic 6x substitutions and parents cultivars Chinese Spring (recipient) and Synthetic 6x ( cbnor) under the drought conditions and control treatments indifferent developing stages were measured. The results indicated that the chlorophyll content of SA,5B chromo substi-tution lines and the corticoid content of SB chromosome substitution line were significantly higher than Chinese Spring at0. OS or 0. 0l level from booting to grain filling stage under normal condition,while the chlorophyll content of 3A,4Dchromosome substitution lines and the corticoid content of 2A and 4D chromosome substitution lines were significantlyhigher than Chinese Spring at 0. OS or 0. 0l level under drought stress. It was concluded that the genes of controllingchlorophyll and corticoid content were probably located on SA,5B and SB chromosomes respectively under normal condi-tion,and that of controlling chlorophyll content and corticoid content were probably located on 3A,4D and 2A,4D chro-mosomes of Synthetic 6x respectively under drought stress.

Key words: Wheat substitutions lines, Drought stress, Chlorophyll content, Corticoid content, Chromosomal regulation
