Classification of Some Black Cumin Seed (Nigella sativa L.) Genotypes According to Phenological and Agronomic Characteristics under Mardin Ecological Conditions

Abstract

This study was carried out with 3 repetitions according to the randomized blocks trial design in 2018-2019 and 2019-2020 planting periods as winter and summer crops in order to determine the phenological observations values and agronomic characteristics of some black cumin (Nigella sativa L.) genotypes in different planting periods under Mardin ecological conditions. Çameli variety and 18 different black cumin seed genotypes were used in the study. In the study, genotypes were grouped according to the parameters obtained from phenological observations and agronomic characteristics by cluster analysis. According to the results of the cluster analysis, it was observed that the genotypes of İzmir, Konya, Burdur, Burdur-1, Eskişehir, Eskişehir-3, Eskişehir-4, Eskişehir-5 were in the first cluster, and the genotypes of Amasya, Çameli, Diyarbakır, Mersin, Samsun, Samsun, Suriye, Adana Şanlıurfa, Şanlıurfa-1, Tokat and Tokat-2 were in the second cluster, and it was determined that the genotypes in the first cluster had higher averages in terms of all phenological and agronomic characteristics. As a result of the study, it was determined that Eskişehir-5 (G9) genotype performed better than other varieties and genotypes in terms of seed yield. In terms of the parameters examined in winter planting, the values were found to be higher than summer sowing and it was determined that winter sowing was the most suitable sowing time for black cumin cultivation under Mardin conditions.
