Наивысшую интегральную оценку, основанную на сумме рангов оценок по урожайности и стабильности I укоса, получили перспективные номера 1580 (15+) и 1504 (8+), которые сочетали высокую урожайность сухого вещества (5,803-6,209 т/га) с низкой вариансой стабильности (-0,016-0,077). По урожайности и стабильности отавы наивысшую интегральную оценку получили номера № 1504 (14+), № 1514 (12+), № 1595 (11+) и № 1580 (10+). Позднеспелые сорта Бойкивчанка, Маричка и номер № 1516 по результатам I укоса и отавы отличились самыми низкими интегральными оценками. Использование интегральной оценки позволило выявить наиболее ценные для селекционного использования номера ежи сборной: № 1580, № 1504 и № 1514.</p></abstract><trans-abstract xml:lang="en"><p>The article deals with the results of the research on the environmental stability of 12 varieties and numbers of orchard grass (Dactylis glomerata L.). Numbers 1580 (15+) and 1504 (8+) have the highest integral estimation based on the sum of the estimations on yield and stability of I cut. These varieties combine high yield of dry matter (5,803-6,209 t/ha) with stability variance (-0,016-0,077). In terms of aftergrass yield and stability numbers 1504 (14+), 1514 (12+),1595 (11+) and 1580 (10+) have the highest integral estimation. According to the results of I cut and aftergrass late varieties Boikivchanka, Marichka and number 1516 have the lowest integral estimation. The use of the integral estimation allows identifying the numbers of orchard grass 1580, 1504, and 1514 which are the most valuable for breeding.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Becker, H.C.
