Agrobiological characteristics of naked oat samples (Avena sativa l. subsp. nudisativa) from the IPGR Sadovo collection
Keywords:
Erysiphe graminis f.sp. avena; oats; Puccinia coronifera; structural elements of yieldAbstract
The study was carried out in the experimental field of IPGR-Sadovo during the period 2017-2019. The aim of investigation was to establish the productive capacity of 7 naked oats accessions and found their resistance to the powdery mildew- Erysiphe graminis f. sp. avenae and leaf (crown) rust - Puccinia coronifera. It was determined that with the shortest length of vegetation period were St Мinа, B4000198, B4000200 and B7000124, with the lowest stem was B4BM0009, with the largest length of panicle, mass on the main panicle, mass of grain from the main panicle and the number of grains and the number of spikelets was В4000201. The relatively the highest yields were obtained from the samples: B4BM0009 and B1E0539. All these samples certainly of interest to plant breeding and could be included in selection program. The standard Mina variety and accessions B4BM0009 and B4000200 showed very high resistance throughout the growing season to the two pathogens tested.
