Huay Bong 80 is the latest (2008) cassava cultivar from TTDI and Kasetsart University with similar fresh root yield to Huay Bong 60, but has higher root starch content. Its plant architecture is so designed that it withstands higher plant density and fits to existing mechanization. This cultivar has been registered under the Thai Plant Varieties Protection Law [B.E.2542 (1999 AD)]. The cultivars name is given, under the patronage, by HRH Princess Maha Chakri Sirindhorn to commemorate the 80th birthday of the King. |
Characteristic :
Huay Bong 80 has similar fresh root yield potential as Huay Bong 60, but has higher root starch content. Smaller plant and a few branches enable the plant to withstand higher plant population. Additionally, its compact root structure is suitable for machine harvest. It is expected that Huay Bong 80 would be widely adopted for modern cassava production under narrow spacings and mechanization. |
Pedigree : Rayong 5 x Kasetsart 50
