摘要：

Ninety two derivatives derived from rye-wheat crosses were analyzed for their rye chromosome/chromatin constitution using molecular cytogenetic tools FISH and GISH, to detect targeted rye chromatin introgression with minimum linkage drag. Of the 92 recombinants lines analyzed, 17 exhibited one pair of rye chromosome substituting different chromosomes of A, B, and D genomes, 10 lines showed substitution and translocations at the same time and 55 lines had 1BL.1RS translocations. Four lines that had more than 10 chromosomes from rye were alike triticale, whereas remaining six lines exhibited no rye chromatin/chromosome. These lines were evaluated for different agronomic traits such as days to maturity, type of spike, colour of spike, compactness of spike etc. for ascertaining correlation between rye chromatin with morphological traits. © 2016, Archana Sharma Foundation of Calcutta.
