Heritability Analysis and Phenotypic Characterization of Spider Plant (Cleome gynandra L.) for Yield

摘要: Knowledge on phenotypic diversity among existing spider plant accessions is a milestone in the improvement of plant, which highly nutritious indigenous vegetable Kenya. A study involving agronomic and morphological characterization 49 assembled from East South Africa was carried out at University Nairobi Field Station for two seasons randomized complete block design with three replications. Phenotypic data collected growth habit, flower, petiole, leaf stem colour, hairiness, number leaves per height, primary branches, length width, single area, chlorophyll content according to FAO descriptors modifications. Data analyzed using both DARwin software V6 Genstat Version 14. We observed significant differences traits implying great genetic variability evaluated accessions. The high variation further validated Unweighted Pair Group Method Arithmetic mean (UPGMA) clustering method flower colour as key traits. 49-spider were clustered into 2 major groups, each consisting Kenyan African Stepwise regression revealed that height had most influence yield terms plant. also heritability several including days flowering (91%), (99%), branches (94%), area (87%). Our results reveal between different accessions, especially regions could be exploited improve productivity related promising improving crop through direct selection.
