BIOCHEMICAL DEFENCE AND THE NATURE OF GENE ACTION AGAINST 'TIKKA' DISEASE IN GROUNDNUT

Published on

Under the attack of Cereospora Spp. resistant genotypes as studied in groundnut are
capable of maintaining a higher level of chlorophyll, soluble sugar, acid protein,
RNA and total phenol content in their leaves. Gene action study revealed that both
additive x dominance and dominance x dominance gene interactions are important
for total phenol content in the leaves. Biparental matings followed by recurrent
selection of types with increased amount of phenol inthe leaves would be suggested
for the development of 'Tikka' disease resistant genotypes.
 

Keywords: Groundnut, Tikka' disease, Biochemical defence, resistance, susceptible, gene interaction.
