Study on dimensions of the sunflower seeds of the latest NS confectionary hybrids

Abstract

The confectionary/non-oil seed of sunflower hybrids is characterized by a higher content of the hull, which is thicker than the oil seed hybrids of sunflower. These seeds can be of different size and shape, with a hull not completely black. The aim of this study is to examine the dimensions of confectionary seeds of the latest NS sunflower hybrids. The results of the analyzed seed samples of the latest hybrids of second filial (F2) generation (NS-H-6792, NS-H-6489, NS-H-6311) are compared with the results of already-used hybrid seeds (Cepko). Equivalent diameter and linear dimensions of seed are characterized by Malik and Saini, 2016. The highest specific value of the equivalent diameter was 8.25±0.60 mm (NS-H-6792) and the smallest was 7.90±0.30 mm (NS-H-6311). Only 24.33% of the measured seeds were between 15.00 and 15.99 mm long, which is the most frequent length interval. The average seed width is from 7.00 to 7.99 mm (44.33%), while the average seed thickness is from 4 to 4.99 mm, which was measured in 46.67% of examined seeds. From the above results of the linear dimensions it can be concluded that the seeds are the most different in length, while the distribution of the results by width and thickness is less.
