Registration of 'Plateau' Waxy (Amylose-Free) Proso Millet
Additional Document Info
Crop Science Society of America. All rights reserved. Plateau (Reg. No. CV-272, PI 672536), a waxy (amylose-free starch) proso millet (Panicum miliaceum L.) cultivar, was developed by the Nebraska Agricultural Experiment Station. In addition, faculty and staff from University of Wyoming, Colorado State University, and USDAARS, Lincoln, NE, and Akron, CO, assisted in trials and laboratory evaluations. Plateau, tested as 172-2-9, was selected from F4 progeny of a cross, made in 1999, between Huntsman (NE79012/NE79017/3/Cope//Dawn/Common) and PI 436626, a Chinese waxy accession. Waxy starch was the most important selection criteria during early generations, and yield was the predominant factor in selection during variety trials. Variety testing data were analyzed using PROC GLM. Mean grain yield of Plateau (1953 kg ha1) was consistently similar to the female parent, Huntsman, the locally adapted high-yielding cultivar, and higher (3090% higher yield) than PI 436626 (1020 kg ha1), the donor parent of the waxy trait. This line was primarily released for its waxy starch grain and its adequate yield, which was similar to the high-yielding locally adapted proso millet cultivars.
