20.500.12556/DKUM-11622 AGROMORFOLOŠKA VARIABILNOST HIBRIDNIH POTOMSTEV PARADIŽNIKA IN NJIHOVA ODPORNOST PROTI BOLEZNIM AGRO-MORPHOLOGICAL VARIATION OF TOMATO HYBRID PROGENIES AND THEIR RESISTANCE AGAINST DESEASES Raziskava je potekala v letih 2006 in 2007 na Univerzitetnem kmetijskem centru Fakultete za kmetijstvo in biosistemske vede. Vključevala je več genetsko in morfološko različnih sort in njihovih križancev paradižnika, s ciljem, da bi preverili odpornost na nekatere najpomembnejše bolezni, analizirali ključne agromorfološke lastnosti in ocenili primernost posameznih genotipov za kmetijsko pridelavo. Poskus je bil nastavljen po standardni zasnovi naključnih blokov v štirih ponovitvah. Med kvantitativnimi lastnostmi je bila največja variabilnost ugotovljena pri višini rastline in dolžini peclja ploda. Velika variabilnost je bila ugotovljena tudi pri nekaterih kvalitativnih lastnostih kot so oblika, barva in čvrstost ploda. Najbolj čvrste korelacijske povezave so bile ugotovljene med dimenzijami plodov. V letu 2006 je bila ugotovljena dokaj močna okužba z žametno pegavostjo (Fulvia fulva), leto kasneje pa je prevladovala krompirjeva plesen na paradižniku (Phytophthora infestans). Leta 2006 je bila ugotovljena tudi prisotnost črne listne pegavosti (Alternaria solani) na plodovih. Raziskava je pokazala, da so bili nekateri križanci visoko kakovostni in bi jih bilo smiselno vključiti v žlahtnjiteljski program, ali pa jih še nekaj generacij samooplojevati, da bi dosegli želeno homozigotnost in jih nato testirati kot potencialne nove sorte. The research was carried out during 2006 and 2007 at the University Agricultural Centre of the Faculty of Agriculture and Life Sciences. It included a number of genetically and morphologically different varieties of tomato and their hybrids, with the aim to test resistance against some of the most important diseases, to analyse key agro-morphologic characteristics and assess suitability of individual genotypes for agricultural production. The experiment was based on randomised complete block design, in four replications. In terms of quantitative characteristics, the largest variability was found in relation to the height of plants and length of the fruit stalk. Significant variation was also found in terms of qualitative characteristics such as fruit shape, colour and firmness, whereas the strongest correlation was noted between different dimensions of the fruit. Rather strong infection with leaf mold (Fulvia fulva) was noted in 2006, while a year later, late blight (Phytophthora infestans) was the predominant disease. Early blight (Alternaria solani) was frequently observed on fruits in 2006. Research showed that some hybrids were of high quality and it would make sense to include these in breeding programmes or else continue with their self-pollination for a number of future generations in order to achieve the desired homozigosity, and subsequently test them as potential new varieties. paradižnik Lycopersicon esculentum kvantitativne lastnosti kvalitativne lastnosti odpornost na rastlinske bolezni Fulvia fulva Phytophthora infestans Alternaria solani. tomato Lycopersicon esculentum quantitative characteristics qualitative characteristics resistance against plant diseases Fulvia fulva Phytophthora infestans Alternaria solani. true true false Slovenski jezik Angleški jezik Diplomsko delo 2009-09-07 08:26:45 2009-10-19 11:59:56 2022-04-12 00:02:18 2022-04-18 03:20:30 2009 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:YAOOLV1M UNI_Filipic_Boris_2009.pdf UNI_Filipic_Boris_2009.pdf 1 539ECC2EA1CC94B220BDCDA5CD17AF73 4f9cf25e346993f4d68111e201ccd5b6b2e67a933dc2eb944047fefd43ff29b5 311c1e23-7c03-11eb-bb7a-00155d0001ca 20.500.12556/dkum/2ed129d8-34b7-4106-bbf0-026899d29943 https://dk.um.si/Dokument.php?lang=slv&id=10534 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
