Variability studies in wheat (Triticum aestivum L.) under late sown condition

Abstract

Variability and association of plant traits with the grain yield is important to be known for efficient selection. This is especially more important for developing wheat varieties in late sown areas where crop gets relatively less time (110-120 days as compared to 130-140 days) for crop growth and development. Around one-third of the wheat area under high input management falls under late sown category. In North Eastern Plains Zone late sown wheat comprises more than 50% area. The information regarding the extent of variability for important root traits and chlorophyll content and their correlation with grain yield and its components is lacking. Hence the present study was undertaken with a view to studying the extent of variation and degree of association of root traits, chlorophyll content and other yield traits with grain yield under late sown condition.
