Abstract

An experiment entitled “genetic variability in rice populations at Mingora Swat” was conducted at
Agriculture Research Institute (ARI) Mingora Swat during rice growing season 2015 in randomize complete block
(RCB) design with three replications. A set of six rice lines in comparison with check cultivar were evaluated to
study the genetic variability among rice genotypes. Data were recorded for days to 50% flowering, days to 50%
maturity, plant height, tillers per plant, grains per panicle, 1000-grain weight and grain yield. Analysis of
variance showed highly significant differences (P ≤ 0.01) for most of the traits. The least days to flowering were
recorded in line Japonica while maximum days were recorded for line Cibogo. Maximum days to maturity were
recorded for lines Cibogo and PK3445-3-2 while minimum were recorded for line Japonica. Maximum plant
height was attained by check cultivar fakhr-e-malakand while minimum by line Cibogo. Tillers per plant were
observed maximum in check cultivar and minimum for line Pk3445-3-2. Line Pk3445-3-2 showed maximum grains
per panicle and minimum by Japonica. The 1000-grain weight and grain yield were observed maximum in check
cultivar and observed minimum in line Japonica. All of the traits were observed from moderate to high heritability.
Grain yield showed positive and significant correlation with biological yield while other traits showed positive
correlation with grain yield. Check cultivar Fakhr-e-malakand showed high grain yield while lines PK3445-3-2
and IR64 were nearer to check cultivar grain yield. Lowest grain yield was observed for line Japonica. A cross
combination of line Japonica and Fakr-e-malakand can give beneficial result in breeding program to obtained a
sustainable variety in future.
