This experiment consists of two stage i.e: (1)
Study inheritance root re-growth in nutrient culture. The objective of
this research was to study soybean inheritance tolerance to aluminum
stress and gene action at seedling stage and acid soil.
This
research used 120 seeds of F2 population generated from crossing
between Argomulyo (Al-sensitive) with Tanggamus (Al-tolerant). Seeds
were grown in nutrient culture for six days (two days without Al, two
days with Al concentration 1.5 mM and pH 4.0 then two days more without
Al) to see root length under condition stress and recovery. The result
showed root length had high and medium heritability at condition stress
and recovery, that means root length is easily be inherited because root
length was larger influenced by genetic compared to the environment
factors. The root re-growth on F2 population at Argomulyo were 83 plants
and Tanggamus were 33 plants. (2) Study inheritance of agronomy
characters in the acid soil. Studied inheritance tolerance to Al stress
at acid soil showed that number of productive branches, seed weight by
plant and 100 seeds weight had moderate heritability so the characters
were used as character selection for next generation.
