Description Analysis of a six parent diallel cross involving high and low
nitrogen fixing peanut (Arachis hypogaea L.) genotypes revealed
the predominant nature of non-additive genetic variance
for nitrogenase activity and other traits. Germplasm line,
NC Ac 2821 had the highest general combining ability for nitrogenase
activity, total nitrogen, leaf area, and top weight, and
therefore, it should be a good parent for use in breeding programs.
Nitrogenase activity was significantly and positively correlated
with nodule number, nodule mass, total nitrogen, top
weight, and root weight. This evidence suggests the possibility
of breeding for increased nitrogen fixation and thus yield in
peanut.
