Effect of RID substitutions and/or modified rye chromosomes on kernel characters in triticales

Published on

The effect of rye chromosome substitution and modification
were studied on various kernel characters in sixty six
hexaploid triticales. Triticales with a 2R12D substitution
and/or a modified rye chromosome(s} exhibited 'medium'
to 'very low' degree of kernel shrivelling as observed
through increased grain weight and volume of water
displaced by 100-grains. Triticales with a 2R12D substitution
coupled with a modified rye chromosomes like 4R, 6R or
7R, the seed shrivelling is very low. 2R/2D substitution
and modification in the rye chromosomes also had a
favourable effect on seed setting. Triticales with full
complement of rye chromosomes showed 'medium' to
'high' kernel shrivelling and low seed set.
