Registration of 01Ab9663 Spring Malting Barley Germplasm

Abstract

Enlarging genetic pools of barley (Hordeum vulgare L.) germplasm is important for keeping diverse genetic resources available for barley improvement. 01Ab9663 (Reg. No. GP‐209; PI 677387) is a six‐rowed elite line from the cross 93Ab375//92Ab5189/M83. 93Ab375 was derived from the cross Russell/82Ab2322//‘Morex’, and 92Ab5189 was the result of the cross 83Ab5432/85SR40. 01Ab9663 was advanced via the bulk method from the F2 to F5 generations. 01Ab9663 exhibited a 126 and 105% yield advantage over ‘Morex’ and ‘Tradition’, respectively, within 37 locations years of testing in our irrigated trials. It showed on average 81.8% malt extract, significantly higher than all the checks from 21 trials. 01Ab9663 has a semidwarf stature with strong straw, a desirable trait for lodging resistance. These excellent character traits make 01Ab9663 a good choice for germplasm development of future malt and feed lines.

“…Agronomic trait measurement was conducted as described previously (Hu et al., 2021), and the steps are repeated here for convenience. Grain yield and test weight were measured using the Harvest Master system (Juniper Systems, Inc.) on the combine from all locations within the state of Idaho and included similar data from other collaborators at different locations.…”
