Genetic variability and heritability in Ethiopian mustard (Brassica carinata A.Braun)

Abstract

Ethiopian mustard (Brassica carinata A. braun 2n=34), is a species that is one of the six most economically important species on the planet. It originated in north-eastern Africa, most likely on the Ethiopian plateau, as a natural hybrid between Brassica nigra and Brassica oleracea. Even though, the crop has high economic importance, production is limited by a scarcity of high-yielding early mature types, a high concentration of erucic acid (C22: 1) in seed oil, and a high glucosinolate content in the meal. Mustard is mostly farmed in Ethiopia's Central and Southeastern Plateaus' mid- to high-altitude (1700-2800 m asl) areas, which receive 500-1200 mm of annual rainfall. The oldest amphidiploid is B. napus, which is followed by B. juncea and B. carinata. Ethiopian mustard is an annual, biennial, or perennial crop used in Ethiopia for oilseeds or as a green vegetable. Brassicas are economically important species by supplying vitamins, minerals, trace elements, dietary fiber, protein and oil for human consumption and industrial raw materials, as well as feed and condiments. Interspecific hybridization has increased the Brassica crops gene pool by transferring beneficial features from one species to another. High heritability and high genetic progress suggested additive effects, whereas high heritability and low genetic advance indicated dominance and epistatic effects. In Ethiopian mustard, different variables like the heritability of days to flowering, days to maturity, plant height, and 1000 seed weight is high.
