20.500.12556/RUL-172897 Primerjava morfoloških lastnosti štirih žlahtniteljskih linij feminizirane industrijske konoplje (Cannabis sativa) Comparison of the morphological characteristic of four breeding lines of feminized industrial hemp (Cannabis sativa) Raziskava je bila usmerjena v ovrednotenje štirih žlahtniteljskih linij feminizirane industrijske konoplje (Cannabis sativa L.), poimenovanih CHk, G8k, G10k in MERk, pridobljeni iz izbranih starševskih genotipov. Poskusi so bili izvedeni na dveh lokacijah, in sicer v Ljubljani in Krškem, v treh terminih in načinih setve: direktna setev semen na njivo in sajenje sadik, pridobljenih v dveh rokih setve v rastlinjaku. Preizkušali smo odziv rastlin na agrotehnični ukrep vršičkanja. Analizirani so bili nekateri morfološki (višina rastline, masa suhe listne biomase s socvetji, delež suhe snovi, razmerje listi/steblo) ter biokemijski parametri (vsebnost kanabidiola – CBD in tetrahidrokanabinola – THC). Rezultati kažejo, da so se linije med seboj razlikovale glede na odziv na lokacijo, termin setve in vršičkanje. Najvišjo povprečno višino je dosegla linija MERk, največjo povprečno maso socvetij G8k, največje razmerje listi/steblo pa G8k. Največji povprečni delež CBD je imela MERk, medtem ko je CHk dosegla največji povprečni pridelek CBD. Analiza starševskih genotipov je pokazala, da imajo starši pogosto večjo vsebnost CBD, vendar tudi več THC. Največji napredek v žlahtnjenju je bil dosežen pri liniji MERk, kjer se je ohranil visok CBD in znižal THC na zakonsko ustrezno raven. The research focused on the evaluation of four breeding lines of feminized industrial hemp (Cannabis sativa L.), named CHk, G8k, G10k, and MERk, derived from selected parental genotypes. The experiments were carried out at two locations, Ljubljana and Krško, and across three sowing terms and methods: direct sowing of seeds in the field and transplanting of seedlings produced in two sowing dates in the greenhouse. We tested the response of plants to the agronomic practice of topping. Several morphological (height of plants, dry biomass of leaves with inflorescences, dry matter content, leaf/stem ratio) and biochemical parameters (cannabidiol – CBD and tetrahydrocannabinol – THC content) were analysed. The results show that the lines differed in their response to location, sowing date, and topping. The line MERk achieved the highest average plant height, G8k had the highest average inflorescence mass, and G8k also showed the highest leaf/stem ratio. MERk had the highest average CBD content, while CHk achieved the highest average CBD yield. Analysis of the parental genotypes revealed that the parents often had higher CBD content, but also higher THC levels. The greatest breeding progress was achieved with the line MERk, where high CBD content was maintained while THC was reduced to a legally compliant level.
