Cassava (Manihot esculenta Crantz) was introduced to Southeast Asia in the 16th–17th centuries and has since flourished as an industrial crop. Since 1980s, Thailand emerged leading producer exporter of cassava products. This growth coincided with initiation breeding programs collaboration International Center for Tropical Agriculture (CIAT), focusing on root yield starch production. The success Thai can be attributed incorporation valuable genetic diversity from international germplasm resources cross local landraces, which become foundation many commercial varieties. Effective evaluation under diverse environmental conditions led release varieties high stability. A notable is development Kasetsart 50. However, extreme climate change poses significant challenges, including abiotic biotic stresses that threaten content, a potential decline starch-based industries. Future directions must include hybrid development, marker-assisted recurrent breeding, gene editing, along high-throughput phenotyping flower induction. These strategies are essential achieve objectives focused drought tolerance disease resistance, especially CMD CBSD.

Multi-trait selection in multi-environments for performance and stability in cassava genotypes

Frontiers in Plant Science, Journal Year: 2023, Volume and Issue: 14

Published: Oct. 30, 2023

Genotype-environment interaction (GEI) presents challenges when aiming to select optimal cassava genotypes, often due biased genetic estimates. Various strategies have been proposed address the need for simultaneous improvements in multiple traits, while accounting performance and yield stability. Among these methods are mean stability (MPS) multi-trait index (MTMPS), both utilizing linear mixed models. This study’s objective was assess variation GEI effects on fresh root (FRY), along with three primary secondary traits.

Drivers of consumer acceptability of cassava gari‐eba food products across cultural and environmental settings using the triadic comparison of technologies approach (tricot)

Journal of the Science of Food and Agriculture, Journal Year: 2023, Volume and Issue: 104(8), P. 4770 - 4781

Abstract BACKGROUND Nigeria and Cameroon are multi‐ethnic countries with diverse preferences for food characteristics. The present study aimed to inform cassava breeders on consumer‐prioritized eba quality traits. Consumer testing was carried out using the triadic comparison of technologies (tricot). Diverse consumers in villages, towns cities evaluated overall acceptability made from different genotypes. Data both were combined linked laboratory analyses gari used make it. RESULTS There is a strong preference higher cohesiveness brightness especially Cameroon, lower redness yellowness. Relatively hardness springiness values preferred Nigerian locations, whereas Cameroon. Trends solubility swelling power differ between two countries. also reveals that older improved genotype TMS30572 benchmark superior characteristics across regions Nigeria, recently released variety Game changer performs very well In genotypes Obansanjo‐2 TM14F1278P0003 have good stability CONCLUSION wide acceptance single geographical cultural conditions as three acceptable new varieties indicates consumers' surprisingly homogeneous eba. This would enhance breeding efforts develop wider expand potential target areas varieties. © 2023 Authors.
