Description Experiments were conducted to validate markers (Nax1 and Nax2) for salinity tolerance and to study
Physio-morphological and molecular evaluation of F
2 population in wheat (Triticum aestivum L. em
Thell.). Net house evaluation data showed enormous variation among Kharchia65 x WH1105 F
2 plants
including plant height (cm), No. of tillers per plant, ear length (cm), No. of grains /ear, No. of
spikelets/spike, 1000 grain weight (g), No. of grains per plant, biological yield per plant (g), harvest index
(%), main spike weight (g) and grain yield per plant under salt stress condition. All the 208 F
2 plants were
checked for Nax loci. Out of 208 Kharchia65 x WH1105 F
2 plants, 62 plants had both Nax1 and Nax2
loci. All the 62 F
2 plants were divided into seven major clusters interspersed between the two parental
lines with the similarity coefficient of 0.55 Out of these 62 F
2 plants those having higher yield could be
further backcrossed with the parent WH1105 to select salt tolerant wheat lines The information generated
from this study can be used further in the improvement of wheat through various breeding programmes.
