Morphological Evaluation and Protein Profiling of Three Accessions of Nigerian Corchorus Linn. Species

Abstract

Vegetative characters and protein profiles of three accessions of Corchorus species were investigated at the experimental plot of the

Characterization of Morphological Diversity of Jute Mallow(Corchorus spp.)

“…Most accessions were characterized by light green and green leaf color. The presence of leaf lobe Leaf length-width ratio (LWR) The ratio of leaf length to leaf width (5) Petiole length (PL) Length of leaf stalk (cm) (6) Days to 50% flowering (50 FLR) Number of days from sowing to 50% flowering (7) Number of primary branches (PB) Number of branches from main stem (8) Number of secondary branches (SB) Number of branches from the secondary stem (9) Plant canopy (PC) Plant width taken at widest point (cm) (10) Flower diameter (FD) The width of an open flower (mm) (11) Pedicel length (PEDL) The stalk of the flower (mm) (12) Fruit length (FL) Length of mature fruit excluding the pedicel (13) Days to first mature pods (DMP) Number of days from sowing to first mature pod (14) Harvest index (HI) Ratio of total harvestable leaves to total weight of the plant (15) Number of leaves (NL) Counted from individual plant during flowering (16) Biomass yield (BY) Total weight of the plant above the ground surface (gm) (17) Number of pods/plant (NPP) Counted from individual plant at maturity stage (18) Weight of 1000 seeds (W1000S) Measured in weighing balance after counting (19) Seeds per pod (SP) Counted from individual pod (20) Cotyledon color (CC) (3) Light green, (5) green, (7) purplish green (21) Stem color (ST) (3) Brown, (5) green, (7) red-purple (22) Leaf color (LC) (1) Light green, (3) green, (5) dark green, (7) purple, (9) dark purple (23) Leaf lobe (LL) (0)Absent, (1) present (24) Setae (S) (1) Small, (2) large (25) Leaf shape (LS) (1) Ovate, (3) elliptical, (5) cordate, (7) palmate (26) Leaf base (LB) (1) Rounded, (3) sagittate, (5) acute (27) Leaf apex (LA) (1) Acuminate, (3) caudate, (5) acute, (7) pale brown (67%), brown (11.7%), and dark brown (21.3%). The accessions were also highly variable in terms of stipule color and petiole color.…”

“…Osawaru et al [20] used morphological traits and presence of soluble proteins to determine the relationship among three Corchorus species. Traits such as growth habit and stem features appeared to be uniform except for stem color.…”

“…Few studies on genetics of leaf yield and its components have been conducted on Jute mallow; however, only few accessions have been used [11,14,20]. Benor et al [9] assessed patterns of morphological variation in Jute mallow accessions of Ethiopian origin and compared them with those from other parts of the world.…”

The genetic diversity of leaf vegetable jute mallow (Corchorus spp.): A review

“…In this regard, only few studies on genetics of leaf yield traits have been conducted in Jute mallow and only few accessions have been used (Palit, et al 1996;Denton and Nwangburuka 2012;Osawaru et al 2012). These few common parents in breeding programs leads to narrow genetic base of existing varieties thus make them susceptible to crop biotic and abiotic stresses (Kamannavar et al 2015).…”

“…The variation in banding pattern of different proteins are assumed to be equal to the variation in genes coding for these proteins (Osawaru et al 2012). In a study conducted by using proteins to determine the relationship among three Corchorus species, traits such as growth habit and stem features appeared to be uniform.…”
