Abstract
The field plot experiments were conducted in the years 2003–2004. In the first year 23 varieties were tested of dwarf and semi-dwarf naked oats (with dwarfing genes introduced form the Badicoot variety) together with the traditional — tall naked varieties Akt and Polar and hulled variety Chwat. In the next year 18 naked oat dwarf and semi-dwarf varieties and one dwarf hulled oat variety — STH 5630 were compared with the traditional tall oat varieties Polar and Chwat. The introduction of dwarfing genes caused the reduction of plant height from 31 to 50%, compared with the tall varieties Akt and Polar. The height reduction was not dependent on field and weather conditions. The following varieties were distinguished: STH 7091 (naked) — characterized by high panicle density, long panicle with low number of grains per panicle with high weight of 1000 grains; STH 7146 (naked) — with relatively lower panicle density but high grain yield per panicle, caused by higher number of grains per panicle; STH 5630 — characterized by high panicle density and high number of grains per panicle. Any effects of dwarfing genes on growth stages timing, plant development and number of hulled grains were not observed.
