Abstract

A mass selection breeding program was conducted on a heterogonous genetic material collected from different parts of the karkadi growing area to genetically improve the crop in Western Sudan. Eight genotypes were identified on the basis of color and shape of the calyx (sepals); in addition to the morphology of the plant and other agronomic, commercial and quality characteristics were evaluated in an experiments conducted at Abu- Omsaaden and Um-Habeela villages during two successive seasons 2015/16 and 2016/ 17. The Eight main genotypes were named as: El Rahad 1 (control), Line 2, Line 3, Line 4, Line 5, Line 6, Line 7 and Line 8. Yield was used to evaluate the productivity, while partial budget analysis was carried out to evaluate the profitability of the different Roselle genotypes. The combined analysis of variance over seasons and locations revealed highly significant differences among the genotypes for all studied parameters with the exception of plant population/ha. The highest yields of dry calyxes were shown by line 2, line 4 and line 3 giving, 328, 302 and 163 kg/ha, respectively. Significant difference in moisture content was detected between the genotypes No. 4, 2, 5 & 6 which recorded the lowest values (7.511 - 7.683). The genotypes had no significant differences in the total TSS. Highly significant differences (p = 0.01) were recorded between the genotypes in pH. The pH values recorded by the different genotypes ranged from 2.688 to 2.932 (genotype No.3). This range still lies below the level determined by the SSMO specification (2016:2404) which is equal to 3.5. The optical density (O.D) of the different karkadi extracts (diluted 50 times) ranged from 0.004 (genotype No.7) to 0.107 (genotype No.2). The analysis of variance showed marked differences (p = 0.01) between the genotypes. Genotype No. 2 scored the highest value. Marked differences (p = 0.01) in total acidity (19.515-24.030) were recorded between the genotypes. The highest net benefit of (3556 SDG/ha) was recorded by genotype line 2 fallowed by line 4 (3179 SDG/ha) and line 3 (1164 SDG/ha). From productivity, quality and profitability point of view it is recommended that the genotypes line 2, line 4 and line 3 to be grown in the targeted areas of Western Sudan.
