Genetic Variation and Genetic Advance of Three Elite Cassava (Manihot Esculenta Crantz) Clones Under Wet Dry Climate of Lampung

Waxy cassava having high amylopectin content could contribute and increase genetic background. Unfortunately, the genetic parameter information of three elite cassava clones as Waxy, UJ-5, and BW-1 is still limited. Consequently, the objective of this study was to evaluate the genetic variation and...

Description
Summary:Waxy cassava having high amylopectin content could contribute and increase genetic background. Unfortunately, the genetic parameter information of three elite cassava clones as Waxy, UJ-5, and BW-1 is still limited. Consequently, the objective of this study was to evaluate the genetic variation and genetic advance of three cassava clones. This study was conducted on the Integrated Field Lab of Lampung from December 2019 to October 2020. Treatment was arranged by a single factor in RCBD with two replications. There were three cassava genotype clones, as Waxy, UJ-5 (originally Kasetsart), and BW-1 (originally Huay Bong-60). Genetics parameters were analyzed by using Minitab programs (Version 17). Variables observed were plant height, leaf number, attached leaf number, internode number, root number, tuber number, tuber fresh weight, tuber dry weight, stem dry weight, attached leaf dry weight, petiole dry weight, starch content, starch weight, and harvest index. The results showed that most variables had high genetic variation and heritability value except for starch content. Starch content showed a medium heritability value as 50%. Moreover, the genetic advance of starch content and weight were 14 and 18%, respectively. It could be concluded that an environmental factor influenced starch content.
