Quantification of plant biochemicals from certain genotypes of maize and their effect on different degree of infestation of maize spotted stem borer, Chilo partellus (Swinhoe)

Abstract

A total number of twenty-five maize genotypes namely, Shaktiman-1, Shaktiman-2, Shaktiman-3, Shaktiman-4, Shaktiman-5, Devaki, Laxmi, Suwan, RHM-1, RHM-2, RHM-3, Deep Jwala, P-3535, P-3533, P-3550, P-3555, Dekalb-9188, Dekalb-9170, New Cross 76×11, New Cross 72×70, New Cross 73×11, New Cross 73×74, New Cross 52×65, New Cross 53×52 and New Cross 50×58 were assessed for their biochemical contents including Chlorophyll-a, Chlorophyll-b, total Chlorophyll and protein and their effects on Chilo partellus infestation. Results have presented a negative correlation between plant age and total content of Chlorophyll-a, b and total Chlorophyll while a positive correlation found between the injury and content of all the assessed biochemicals.
