Survey and pathogenicity of fusarium wilt disease in cotton fields of Tamil Nadu, India
Cotton is an important crop used globally for its natural fibre and seed. Fusarium wilt, caused by the fungus Fusarium oxysporum f. sp. vasinfectum, is a major disease of cotton capable of causing significant economic loss. The fungus persists in soil as chlamydospores and in association with the ro[r]
Screening of blackgram genotypes for resistance against corynespora leaf spot and cercospora leaf spot
Field screening was done under natural field conditions during rabi 2016- 17 to identify the sources of resistance in blackgram genotypes against leaf spot diseases caused by Corynespora cassiicola, Cercospora canascens. Out of sixteen blackgram genotypes evaluated only one genotype LBG 645 was mode[r]
GENETIC DIVERSITY IN BRINJAL (SOLANUM MELONGENA L.)
The present study was undertaken with the aim of examining the magnitude of genetic diversity and characters contributing to genetic diversity among brinjal genotypes for a planned breeding programme.
SCREENING OF MAIZE INBRED LINES AND POPULARLY GROWN HYBRIDS AGAINST BANDED LEAF AND SHEATH BLIGHT DISEASE INCITED BY RHIZOCTONIA SOLANI F. SP. SASAKII EXNER
Banded Leaf and Sheath Blight (BLSB) disease caused by Rhizoctonia solani f. sp. sasakii Exner was studied in 22 inbred lines and 12 hybrids at the Regional Agricultural Research Station farm, Lam, Guntur, during rabi 2014-15 for evaluating resistance. Out of 22 inbred lines, PFSR9-2 had shown resis[r]
Expression profiling of resistance gene analogs from French bean (Phaseolus vulgaris L.) for the manifestation of rust (Uromyces phaseoli L.)
The resistant french bean genotype Arka Anoop and susceptible genotype Arka Sharath were used for expression profiling of RGAs for the manifestation of rust. Leaf tissue was collected from both resistant and susceptible genotypes which were challenged with rust spores separately at 15 DAI and 45 DAI[r]
Genome-wide analysis of the gene families of resistance gene analogues in cotton and their response to Verticillium wilt
Gossypium raimondii is a Verticillium wilt-resistant cotton species whose genome encodes numerous disease resistance genes that play important roles in the defence against pathogens.

Abscission of fruiting structures in BT and non-BT cotton in relation to abiotic factors and agronomic intervention under rainfed condition
A two year field experiment was conducted to elucidate relation of abscission of fruiting structures in cotton (Gossypium hirsutum) with abiotic factors and effect of agronomic intervention viz., spacing (90 × 60 cm and 90 × 45 cm) and NPK levels (50:25:25, 62.5:31.25:31.25 and 75:37.5:37.5 kg NPK h[r]
Identification of resistant sources for blast and rust in foxtail millet incited by Pyricularia Setariae and Uromyces Setariae-Italica
The present investigation was undertaken to identify the resistant genotypes amongst twelve genotypes of foxtail millet or Italian (Setaria italica L.) for evaluating blast and rust disease severity caused by Pyricularia setariae Nisikado. and Uromyces setariae-italica (Diet.) Yoshino. were studied[r]
