Mrenda (Jew's Mallow) Germplasm Characterization by Morphological Traits

Authors(4) :-Lelei D, Omami E, Ochuodho J, Ngode L

Jew's mallow or Mrenda is widely grown in Africa with its species being highly variable in their morphological traits. In Kenya there are many local varieties widely grown across the counties as indigenous vegetable for its important contribution to diet by supplying high nutrients and medicinal value. The rich genetic variation in the many land races found locally has so far hardly been exploited nor characterized, leaving ample room for development of improved varieties or accessions. The objective was to do characterization of Mrenda morphotypes. Mrenda seed Germplasm was collected using stratified random sampling technique from various counties and planted in pots at green house and morphological traits taken, grouped and analyzed. Characterization results showed presence of two morphotypes based on color and two based on height named: Morphotypes 1(Green Short), Morphotypes 2 (Green Tall), Morphotypes 3 (Brown Short) and Morphotypes 4 (Brown Tall). Plant height showed early maturing variety being short with Morphotypes 1 (28.3 cm) and Morphotypes 3 (29.0 cm) and differentiated by stem color. The shortest variety was from West Pokot, Morphotypes 1 and Morphotypes 3 at height of 26 cm, while tall accession was from Nandi, Morphotypes 1 (31 cm) and Morphotypes 3 (33 cm). The highest pod count per plant was Morphotypes 1 at 14 pods from Simlaw seed selection while lowest was 5 pods (West Pokot, Keiyo and Trans Nzoia). On late maturing variety, West Pokot had both the shortest, Morphotypes 2 (79 cm) and Morphotypes 4 (77 cm), while Nandi had the tallest (93 cm) from Morphotypes 2 and 84 cm from Morphotypes 4. Generally the Green types were taller than Brown types. Highest Pod count per plant was from Nandi on both Morphotypes 2 and 4 at (19 pods) and lowest was from West Pokot (16 pods). It is concluded that there was variation in traits of Mrenda Germplasm thereby needing purification of accessions to separate them into various morphotypes for farmer’s crop production purposes.
