Thousand seeds weight in industrial hemp genotypes - Comparative analysis
Abstract
The study evaluated thousand seeds weight (WTS) in several genotypes of industrial hemp. The field researches were done within ARDS Lovrin. Seven genotypes of industrial hemp were used in the present study: Hg601, Hg602, Hg603, Hg618, Hg622, Hg625, and Hg628. The crop was carried out in non-irrigated conditions, in repetitions for each genotype. The seeds were harvested at physiological maturity. Thousand seed weight was determined by the classical method, by weighing modules of one thousand seeds each. A normal distribution of WTS values was recorded, with r = 0.986. In relation to the mean value (WTS_m = 17.691 g), there were positive differences in the Hg603 genotype (p < 0.01, **), and in the HG602 genotype (p < 0.05, *). Negative differences were recorded for the Hg618 genotype (p < 0.05, o). In the case of the median value, a positive difference was recorded for the Hg603 genotype (p < 0.05, *), and a negative difference for the Hg618 genotype (p < 0.05, o). The cluster analysis grouped the genotypes based on similarity into two distinct clusters (Coph.corr. = 0.775). The WTS parameter is important for industrial hemp for sowing, and for crops quality. At the same time, it is also important for the valorization of seeds in the food industry, seeds with high WTS values show a high consistency, with a high useful fraction (kernels) for different functional products.
