Abstract

Spider plant, Cleome gynandra L (Cleomaceae) is an important traditional leafy vegetable in Burkina Faso diets. Due to its high nutritional value and medicinal properties, it is a good dietary supplement for combating nutritional deficiencies and certain degenerative diseases. However, the lack of quality seeds and poor agronomic performance are limitations to crop improvement. The aim of the present study was to evaluate the agro-morphological performance of a collection of C. gynandra in relation to the three climatic zones of Burkina Faso. Thus, 36 accessions collected in the three climatic zones of Burkina Faso were evaluated using a Fisher block design. The trials were conducted in August 2019 during the rainy season in the country's three climatic zones. Measurements and observations were made on the traits of interest, including fresh biomass (BMF). The best agronomic performances were recorded at the Bobo Dioulasso Experimental Station, followed by Ouagadougou, while the poorest performances were noted at Dori. The stability test (AMMI and GGE biplot) enabled us to identify accessions adapted to each climate and six high-performing, stable accessions (OUA9, OUA10, KOU, KOM2, BOB3 and MAN) for all three climatic zones. These high-performing, stable accessions can then be popularized among local populations.

Key words: Cleome gynandra, agronomic performance, yield in fresh biomass, AMMI, Burkina Faso.
