Selection of Cassava (Manihot esculenta Crantz.) Clones from Hybridization for Yellow Roots Flesh

Cassava with yellow roots flesh and good taste are suitable for consumption and it can increase its nutritive value. Until now, cassava varieties suitable for consumption have only four varieties namely Adira 1, Malang 1, Malang 2, and Darul Hidayah, so the development of new high-yielding varieties should be carried out. The 99 clones including two control varieties were planted in a single-row trial at Jambegede Research Station, Malang, East Java. This study aimed to evaluate cassava clones with yellow roots, high yield, and suitability for food. Correlation and cluster analysis were carried out on phenotype data. In addition, qualitative traits are reported in the description forms. The results showed the diversity of various characters of leaves, stems, and roots. The root yield was significantly correlated with the harvest index, the number of large roots, and the diameter of the large roots. Cluster analysis resulted in a dendrogram divided into two main groups. There were 53 clones of yellow root cassava which indicated high beta carotene content. The root yield ranged from 0.02 kg to 9.39 kg with an average of 2.25 kg. There were 48 clones with root yields above the average of control varieties. Six clones were obtained with high-yield potential roots, yellow roots flesh, and non-bitter taste, namely 4-14, 7-4, 5-3B, 9-2, 5-3A, and 12-7. © 2024 American Institute of Physics Inc..
