20.500.12556/DKUM-68960 Growth performance, productivity and diseases susceptibility of barley varieties in Slovenia within the Cobra project's site comparison Rast, produktivnost in občutljivost na bolezni sort jarega ječmena preskušanih v okviru projekta COBRA v Sloveniji Different plant genotypes react differently in different climates. A field experiment was carried out to estimate the growth performance, productivity and diseases susceptibility of spring barley varieties in the Slovenian climate. We received some varieties, mainly of Nordic origin, from the Technical University of Denmark, a COBRA project partner, which were previously tested in estimated future climate in RERAF phytotron. Varieties of the highest grain yield (3,993 kg ha$^{-1}$ in ‘Evergreen’ to 5,146 kg ha$^{-1}$ in ‘Sebastian’) were rather shorter (58.7 cm to 67.1 cm) and mostly had the highest specific grain weight (54.3 to 58.6 kg 100 L$^{-1}$) and 1000-kernel weight (30.2 to 37.1 g). They developed 1,561 to 2,532 tillers m$^{-2}$ and 515 to 840 ears m$^{-2}$ and reached a heading stage between 13th and 25th of May. The tested varieties seem rather insusceptible to most common diseases, but susceptible to cereal leaf beetle attacks. Odziv na različne podnebne razmere je genotipsko specifičen. V poljskem poskusu smo na sortah jarega ječmena ocenjevali rast, višino pridelka in občutljivost na bolezni v slovenskih pridelovalnih razmerah. Sorte ječmena, predvsem nordijskega izvora, smo prejeli od partnerske institucije Technical University iz Danske, ki je sodelovala v projektu COBRA. Vse sorte so bile predhodno preskušane v fitotronu RERAF, v klimatskih razmerah, ki simulirajo pričakovane podnebne razmere v prihodnosti. Skupina sort z značilno najvišjimi pridelki (med 3.993 kg ha$^{-1}$ pri 'Evergreen' in 5.146 kg ha$^{-1}$ pri sorti 'Sebastian'), so bile značilno nižje (58,7 cm do 67,1 cm) in so imele med preskušanimi sortami v večini najvišjo hektolitrsko maso (54,3–58,6 kg 100 L$^{-1}$) ter maso 1000-zrn (30,2 ̶ 37,1 g). Razvile so med 1.561 in 2.532 m$^{-2}$ stranskih poganjkov in med 515 in 840 m$^{-2}$ poganjkov s klasom. Razvojno fazo klasenje so sorte dosegle med 13. in 25. majem. Preskušane sorte so bile na najpogostejše bolezni ječmena precej neobčutljive, vendar dovzetne na napad žitnega strgača. organic breeding barley varieties productivity disease susceptibility ekološko žlahtnjenje ječmen sorte produktivost občutljivost na bolezni true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-11-14 12:24:40 2017-11-14 12:25:38 2022-08-01 16:31:41 2019-07-11 17:16:31 2016 0 0 str. 1-4 št. 1/2 Letn. 13 december 2016 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1580-8432 633.1:631.147 116855808 4317996 10.1515/agricultura-2017-0001 1580-8432 URN:SI:UM:DK:HTQCERX9 Agricultura_2016_Grobelnik_Mlakar_et_al._Growth_performance,_productivity_and_diseases_susceptibility_of_barley_varieties_in_Slovenia_wi.pdf Agricultura_2016_Grobelnik_Mlakar_et_al._Growth_performance,_productivity_and_diseases_susceptibility_of_barley_varieties_in_Slovenia_wi.pdf 1 4263CE793C1CB90E9726D909E62A62AD b216e5223b9291065c51cf89913b9c90b276febf304fd9ba933f70db51056707 7eba0b0c-7c0f-11eb-bb7a-00155d0001ca 20.500.12556/dkum/5246c875-5ec5-47b7-8b0c-7d3e71f19948 https://dk.um.si/Dokument.php?lang=slv&id=120265 http://www.degruyter.com/view/j/agricultura.2016.13.issue-1-2/agricultura-2017-0001/agricultura-2017-0001.xml 1 https://dk.um.si/Dokument.php?lang=slv&id=120264 Fakulteta za kmetijstvo in biosistemske vede Agricultura 0 0 0
