Analysis segregation and prediction of gene action controlling soybean tolerance to aluminum toxicity
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2014, Vol 5, Issue 4
Abstract
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 (Alsensitive) 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.
