Effects of reduced plant height on breeding requirements and ...

usual-ly associated with t ower yiefds, this may have been a
substantial factor. ínfluencing the yield <strong>of</strong> these lines.
The matu-rity factor and the total lack <strong>of</strong> F x G interaction
for yield are inportant from the breederos viewpoint"
The results indicated that early maturing, seni_dwarf barì-ey
sel"eetions may not yield as well as standard <strong>height</strong> geno_
types. Furthermore, these shorter genotypes apparently wíll
need inherently superior yielding ability, since they did
not respond differently than the talls to applied lt, to be
superíor in yield to the best tall genotypes"
0n the other hand, when given adequate nutrition and
reasonable growing conditíons, the later maturing semi_d.warf,
M\nn64-62, performed well. Furthernore, the improved stnaw
strength <strong>of</strong> the semi-d.warfs would nake them superior, since
the criticaL fact is that semi-dwarfs which are equaL to
tal1 genotypes under norüal growing conditions should yiel
