Abstract :
Aresearch experiment was conducted to investigatethe variability and heritability in F2populationof spring wheatatthe experimental field of Sothern Wheat Research Station, Tandojam during 2014-15.The experimental material consistedof8F2hybridviz: Sassui x Anmol-91, WL-711 x Anmol-91, Sassui x Johar, Abadgar x SKD-1, Sassui x Abadgar-93, Marvi x Noori, Moomal-2002 x Anmol-91, Marvi x Sassuiand their parents were sown in Randomized Complete Block Design (RCBD) with 3 replications. Genotype werehighly significant at0.01level of probabilityfor days to 75 % heading,days to 75% maturity, plant height, spike lengthand spikelets spike-1.The highest heritability(95.39%)regarding spike lengthwasdisplayed by cross WL-711 x Anmol-91. Spike lengthis the main contributorsto the grain yield and may be kept as selection criteriafor developing high yieldingvarieties.The F2populationSassui x Anmol-91andWL-711 x Anmol-91 could be selected for higher yield in advanced generations.
