INHERITANCE OF SOME QUANTITATIVE CHARACTERS IN SIX-ROWED BARLEY

Abstract

An experiment was undertaken to study the genetic behaviour of yield and certain yield traits using generation mean analysis in six-rowed barley (Hordeum vulgare) The material comprised of parental (P lI Pz), Fl , Fz, F3, BCl and BCz generations of 2 crosses viz., [(RO 137/RS6) x (CN 292/RDB 1)] and [(RO 137/RS 6/CN 292/ROB 1) x (Mexican 19/Russian 20/RS6/Mexican 19)] referred to as cross I and cross II in the present study. The material was grown in RBO with 3 replications. Non segregating generations (Pv Pz, Fl ) were grown in a single row, back cross generations (BCl and BCz) in two rows and Fz and F3 in 5 rows of 2 m length. The plant to plant and row to row spacing were maintained 10 em and 20 em respectively. Standard agronomic practices were followed to raise a normal crop. Ten competitive plants from each parent and Fv 20 from BCl and BCz, 40 from Fz and F3 per replication were taken at random for recording observations on days to heading, plant height, spike length and grain yield/plant.
