PERFORMANCE OF BARLEY N.P. 109 IN THE NORTH INDIAN HILLS

Published on

Barley is grown widely in the north Indian hills from foot hills to areas
located at altitudes of more than 4,000 meters a.s.!. It is attacked by rusts,
Puccinia graminis tritici and Puccinia striiformis and under favourable conditions
these cause heavy losses. Barley also constitutes an important source of inoculum
of rust spores which disseminate from the hills to the plains causing fresh
recurrence of this disease every year. Consequently, evolution of rust resistant
barley varieties forms an important part of the cereal breeding programmes for
the hills. In these programmes, main emphasis is laid on breeding for yellow
rust resistance as this rust appears early and causes greater damage. Black rust
appears late in the season in most areas when the barley crop is almost mature
and consequently does not cause any appreciable loss in yield.
