Crossablity of seventeen disomic /ditelosomic wheat rye addition lines
with three bread wheat genotypes is determined. All cross combinations (51)
are highly crossable except 4 and 5, which had seed set percentage below
60. It was also noticed that a specific combination (6R x HD29) had very
high percentage of seed set (92.98). In some cases like 4R x PBW343, crossability
is very poor (39.69%), which suggested that crossability of wheat-rye addition
lines vary with different wheat genotypes. It is desirable to select highly
crossable disomic/ ditelosomic lines and bread wheat’s to transfer
crossability genes of these genotypes to the attractive wheat parent, which
can then be used in for further wheat improvement programme.
Key words: Crossability, wheat-rye addition lines, wheat genotypes.
