Generation Mean Analysis of Maydis Leaf Blight Resistance in Maize

Efficacy of Newer Molecules, Bioagents and Botanicals against Maydis Leaf Blight and Banded Leaf and Sheath Blight of Maize

Maize (Zea mays L.; 2N=20) is major staple food crop grown worldwide adapted to several biotic and abiotic stresses. Maydis leaf blight (MLB) and banded leaf and sheath blight (BLSB) are serious foliar fungal diseases may cause up to 40% and 100% grain yield loss, respectively. The present studies were undertaken to work out the efficacy of chemicals, botanicals and bioagents for the management...

Analysis of quantitative trait Loci for resistance to southern leaf blight in juvenile maize.

ABSTRACT A set of 192 maize recombinant inbred lines (RILs), derived from a cross between the inbred lines Mo17 and B73, were evaluated as 3-week-old seedlings in the greenhouse for resistance to southern leaf blight, caused by Cochliobolus heterostrophus race O. Six significant (LOD >3.1) quantitative trait loci (QTL) were identified for disease resistance, located on chromosomes 1, 2, 3, 6, 7...

Generation Means Analysis of Leaf and Stem Resistance to Gummy Stem Blight in Cucumber

Leaf and stem resistance to gummy stem blight [Didymella bryoniae (Auersw.) Rehm.] in five resistant by susceptible crosses of cucumber (Cucumis sativus L.) was investigated using generation means analysis. No single gene of major effect controls either leaf or stem resistance to gummy stem blight in these five crosses. The mean number of effective factors controlling leaf resistance in the cro...

Turcicum Leaf Blight Resistance in Maize: Field Screening of New Inbreds and Hybrids

This paper presents identification of sources of Turcicum Leaf Blight (TLB) resistance in maize. Maize is affected by more than 60 diseases, of which 16 are major ones. TLB, caused by E. turcicum, is considered a serious disease where climatic conditions are cool with high relative humidity. Severe losses in grain yield ranging from 25 to 90 per cent have been reported in India. Seventy two hyb...
