Association and path analysis in F3 generation of single and three-way crossesof rabi sorghum [Sorghum bicolor (L.) Moench]

Abstract

F3 families developed from crosses M 35-1 x Kodamurkhi local and M 35-1 x Kodamurkhi local x Biligund localwere evaluated in family block design for nine productivity traits during rabi 2019. Number of green leaves, plant height,panicle length, panicle width and panicle weight showed positive and significant correlation with grain yield while SPADshowed negative association with plant height. Path analysis showed that panicle weight contributed high direct effect tograin yield per plant followed by number of green leaves, plant height, and panicle width in single cross whereas, numberof leaves, number of green leaves and panicle length in three-way cross.
