Abstract
Experiments were conducted to evaluate segregating HKR47 x MAS26 (aerobic) F3 plants for
various physio-morphological and root traits and allelic diversity for 7 microsatellite markers linked to
the root traits. In HKR47xMAS26 F3 plants enormous variation was observed for plant height, panicle
length, and number of tillers per plant, seeds per panicle, percent seed setting, root length, root
thickness, root volume, fresh and dry root weight, 1000 grain weight, grain length/breadth ratio and
yield per plant. The NTSYS-pc UPGMA cluster tree analysis led to the grouping of 46 F3 plants in two
major groups at a similarity coefficient of 0.5. All the 46 F3 plants clustered in two major groups at the
similarity coefficient of 0.50. Major group I consisted of HKR47 and 16 F3 plants while the major
group II had MAS26 and 30 F3 plants. A number of promising F3 plants have been selected, which had
higher grain yield, root length and biomass greater than the parental rice varieties (MAS26 and
HKR47)for further progeny analysis.
