Inheritance of leaf chlorophyll content in groundnut (Arachis hypogaea L.)

Published on Jan 18, 2021 12:08 PM

In groundnut, water-use efficiency is governed by the
photosynthetic capacity which is dependent on leaf
nitrogen status. Leaf nitrogen status is ultimately reflected
in the chlorophyll content. Chlorophyll content of different
genotypes/individual plants in segregating generations in
a relative manner can be obtained through SPAD
chlorophyll meter reading (SCMR). The experimental
material consisted of 300-350 F
2 plants in each of five
crosses involving a common male parent. Individual plants
were screened for SCMR in F
2 populations of each cross
and the data were grouped taking a class interval of two.
From the perusal of F2 frequency distributions of five
groundnut crosses and the results of skewness and
kurtosis, it could be inferred that leaf chlorophyll content
in groundnut may be a quasi-quantitative trait with
modifiers acting either to increase or decrease the
expression of the trait in different genetic backgrounds
as in the present study
