Morphometric and agronomic characterization of 56 ginger landraces in Burkina Faso

Abstract

Objective: This study aims to characterize and assess the variability within the ginger accessions growing in Burkina Faso for morphometric and agronomic traits in order to identify appropriate strategies for the future breeding program. Methodology and Results: The experiment was conducted with 56 accessions in Randomized Complete Block Design with four replications. Moderate diversity was observed for morphometric and agronomic characters. The linear Pearson's correlations between rhizome yield and rhizome weight per plant were significantly positives with the other characters, except days taken to maturity, which were negatives. Plant height was strongly associated with number of leaves, leaf length and rhizome width. The accessions gathering into two groups is not made according to their origin, but mainly on the basis of the characters such as rhizome yield, rhizome weight per plant, rhizome length, and plant height. Conclusion and application: The ginger germplasm characterization is useful and has made it possible to understand the basic information for development of a scientific strategy for the efficient conservation of ginger. Strong associations between yield components and plant seize are important selection indices of rhizome yield and may be emphasized in the breeding programs for genetic improvement. Moreover, the model of clustering of the accessions can be used as a base for the choice of genotypes with interesting agro-morphological characteristics for the improvement of ginger productivity.

Ginger germplasm classification and identification of morphological markers related to rhizome yield

“…The correlation result in this study showed that rhizome yield would improve with an increase in pseudo-stem diameter, plant height, leaf width, and the number of leaves plant −1 . This result aligned with earlier studies (Lincy et al, 2008;Nandkangre et al, 2016) that reported a significant positive correlation of rhizome yield with pseudo-stem diameter, plant height, leaf length and width, number of leaves plant −1 and number of tillers plant −1 . Tall plants with broad leaves tend to have better photosynthetic capacity than plants with narrow leaves (Wang et al, 2019).…”

“…The dendrogram grouped the ginger genotypes based on their high-and low-performing attributes compared with the population mean. Variation in rhizome yield and biochemical composition of ginger germplasm has been linked to their genetic differences (Chukwudi et al, 2020;Eleazu et al, 2012;Kizhakkayil & Sasikumar, 2012;Nandkangre et al, 2016;Pattnaik et al, 2016;Sendanayake et al, 2017). Pattnaik et al (2016) showed genetic variability in 20 elite ginger genotypes in India using cluster analysis.…”

Effets De La Fertilisation Sur Les Nématodes Parasites Et Le Rendement En Rhizomes Frais Du Gingembre, Zingiber officinale Rosc

“…Originaire d'Asie du sud-est (Preeti et al, 2008), le gingembre est cultivé essentiellement pour ses rhizomes. C'est l'une des plus importantes épices au monde de par son importance économique et ses nombreuses vertus médicinales (Nandkangre, 2015). Les nombreuses vertus médicinales (amélioration de la qualité du sperme, protection de l'Acide Désoxyribonucléique, anticoagulant, anti-hypercholestérolémie, antihyperglycémiant, antispasmodique, antimicrobien, etc.)…”
