Productivity of homogeneous and heterogeneous oat populations at two sowing dates

Eight spring oat (Avena sativa L.) lines differing in height and maturity were categorized into three gropups. Group 1 contained lines variable in height and maturity whereas Groups II and III were variable in maturity and height respectively. The lines in each group were grown in pure lines and in blends and two sowing dates to study the effect of different sowing dates on homogeneous and heterogeneous oat populations. The traits measured were vegetative growth rate reproductive growth rate and grain yield. The means of homogeneous lines and heterogeneous oat populations performed equally in both growth rate and grain yield. The grain yields of the blends were within the range of their component pure lines and the blends did not show any advantage at the late sowing date.

Abstract

Eight spring oat (Avena sativa L.) lines differing in height and maturity were categorized into three gropups. Group 1 contained lines variable in height and maturity whereas Groups II and III were variable in maturity and height respectively. The lines in each group were grown in pure lines and in blends and two sowing dates to study the effect of different sowing dates on homogeneous and heterogeneous oat populations. The traits measured were vegetative growth rate reproductive growth rate and grain yield. The means of homogeneous lines and heterogeneous oat populations performed equally in both growth rate and grain yield. The grain yields of the blends were within the range of their component pure lines and the blends did not show any advantage at the late sowing date.
