Abstract:Razvoj ponovljive in časovno učinkovite metode diagnostike zdravstvenega stanja in identifikacije semena v programu žlahtnjenja lahko pripomore k povečanju razvoja novih kultivarjev. Cilj študije je bil oceniti potencial multispektralne metode prikazovanja (ang. multispectral imageing) in bližnje infrardeče refleksijske (NIR) spektroskopije posameznega semena (SKNIR) za določljivost bolezni semena in razločevanje sort ozimne pšenice in tritikale. Ti metodi bi lahko bili aplicirani tako v konvencionalni kot tudi v ekološki program žlahtnjenja. V analizo je bilo vključenih devet sort tritikale in sedemindvajset sort ozimne pšenice. Z uporabo multispektralne metode smo lahko uspešno prikazali detekcijo in separacijo neokuženega in okuženega dela povrhnjice semena s Fusarium spp. SKNIR smo uporabili za zaznavo in diferenciranje med vsemi šestintridesetimi vključenimi sortami, in sicer na osnovi spektralnih razlik, ki so posledica razlik v kemični sestavi semena različnih sort. Raziskava nas je privedla do zanimivih spoznanj, ki bi lahko s kombiniranjem podatkov iz obeh večspektralnih metod koristila nadaljnjim študijam za razvoj klasifikacijskega modela za analize kakovosti semen in separacijo sort.

Title:APPLICATION OF IMAGE-SPECTROSCOPY METHOD FOR IDENTIFICATION OF VARIETIES AND SEED-BORNE DISEASES
Abstract:Developmental of rapid and time-efficient health diagnostic and identification technology in breeding programs could increase the availability of new varieties. The aim of the study was to evaluate the potential of multispectral imaging and single kernel near-infrared spectroscopy (SKNIR) for determination of seed health and variety separation of winter wheat (Triticum aestivum L.) and winter triticale (Triticosecale Wittm. & Camus) which could be applied to conventional as well as organic breeding programs. The analysis included nine winter triticale varieties and 27 wheat varieties. With use of a multispectral imaging device (405-970 nm wavelengths) on Fusarium spp. infected and uninfected parts of the seed surface could successfully be distinguished. SKNIR was applied in this research to differentiate all 36 involved varieties based on spectral differences due to variation in the chemical composition. The study produced an interesting result, which could be use in further studies for a sorting model development by combining data from multispectral imaging and SKNIR for identifying of seed quality and varieties.
