Comparing eight patato breeds growth in the soil of Xuan Hoa of Vinh phuc province photosynthesis after 20 days; 35 days and 50 days of growth, we have found the following: the total content of chlorophyll, Diamont, Eben and Solara have the greatest capacity; Redstar, HH7 and CV38.6 have the medium capability; KT3 and Mariella have the least.
Regarding the photosynthesis, Eben, Redstar and Diamont have the greatest capacity for photosynthesis; KT3, Mariella and CV 38.6 have the medium capability; HH7 and Solara have the least potential.
Our Comparing eight patato breeds in productivity shows that: Eben, CV38.6 and Redstar produce the highest yield; KT3, Mariella and Diamont produce the medium yield; HH7 and Solara produce the lowest yield.
