Abstract
A research experiment was conducted to investigate the variability and heritability in F2 population of
spring wheat at the experimental field of Sothern Wheat Research Station, Tandojam during 2014-
15.The experimental material consisted of 8F2 hybrid viz: 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 Sassui and their parents were sown in Randomized Complete Block Design (RCBD) with 3
replications. Genotype were highly significant at 0.01 level of probability for days to 75 % heading,
days to 75% maturity, plant height, spike length and spikelets spike-1. The highest heritability (95.39%)
regarding spike length was displayed by cross WL-711 x Anmol-91. Spike length is the main
contributors to the grain yield and may be kept as selection criteria for developing high yielding
varieties. The F2 population Sassui x Anmol-91 and WL-711 x Anmol-91 could be selected for higher
yield in advanced generations.
