Abstract: In
order to ascertain the diversity for its possible utilization in rice
grain quality improvement in Pakistan, local rice genetic resources (475
accessions) collected from 3-rice cultivation zones and other parts of
the country were investigated for the seed characters. The distribution
patterns of some interesting observations were also carried out. A wide
variation was found in grain size and shape. Pakistan rice cultivars
were dominated by long grain type while the short grains were absent,
according to the measured length. However, based on grain length/width
ratio, 1.3 % short grain types were present in NWFP/N. Areas.
