The development of biotypes and existence of variability in Brown planthopper population always demands for the identification of new sources of resistance from time to time. However, the presence of desirable quality and yield traits in the genotypes along with source of resistance to BPH will be a[r]

Pseudomonas sp. PG2982 [23]. The enzymes isolatedfrom these bacteria were designated as class II EPSPson the basis of their catalytic efficiency in the presenceof high glyphosate concentrations and their substantialsequence variation as compared with EPSPs fromplants or E. coli [24]. Other cla[r]

Performance of modern cultivars in terms of yield under organic farming differs from that of conventional system. As the demand for organic rice is increasing, so to maintain high productivity, there is a need to evaluate modern high yielding rice varieties under organic farming systems. Field exper[r]

The most important diseases of eucalyptus in the plantations are leaf and shoot blight caused by Cryptosporiopsis eucalypti and associated with defoliation, dieback and mortality of eucalyptus trees. Disease causes major losses in nurseries and plantations resulting in failure of planting material a[r]

A field experiment was conducted at the research plot of the Department of Plant Pathology, SHIATS, Allahabad, U.P. during the Rabi season of 2013-14 to evaluate selected bioagents, plant extracts and fungicides for the management of Alternaria blight of Indian mustard (Brassica juncea L.) by applyi[r]

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]

Two year field screening was undertaken during Kharif season of 2011 and 2012 with eight varieties of Mungbean to ascertain its resistance against Yellow mosaic virus disease. It is evident from the pooled data that no varieties/ lines showed complete resistance to YMV disease during both the consec[r]

Okra genotypes were evaluated for their genetic variability, character associationships and genetic divergence among fifteen quantitative traits by adopting Randomized Block Design.

The experiment “studies on collection and evaluation of genetic variability available in Amaranthus under Chhattisgarh plain condition” was conducted at Horticulture Research cum Instructional Farm, Department of Horticulture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during Rabi 2014-15.[r]

The rice crop is affected by various biotic and abiotic stresses. The fungal diseases come under major biotic stress, among fungal diseases sheath blight of rice is one of the major threat for cultivation of rice crops. The sheath blight pathogen (Rhizoctonia solani Kühn) is being affected by differ[r]

There have been numerous attempts to transfer Papaya ringspot virus type P (PRSV-P) resistance from wild Vasconcellea relatives to Carica papaya L. Success has been limited by the high degree of genetic divergence and incompatibility. In the present work, the advanced intergeneric population of Cari[r]

Considering these facts, the present study was undertaken to determine the suitable plant density and nitrogen level for optimum growth and improved radiation use efficiency of transplanted rice.

The current investigation was performed with two major objectives: Assessment of BPH resistance of the batch of converged rice cultivars and local rice varieties; Phylogenetic analysis and using marker molecular-based breeding methods to develop the excellent 2-3 cultivars with sustained resistance[r]

For screening of the transformants, one mature leaf wasexcised from each individual plant, placed in an Eppendorftube and frozen in liquid nitrogen. Frozen tissue waspulverized in 200 lL protein extraction buffer [PEB: 100 mmTris ⁄ HCl, pH 8.0, 50 mm EDTA, pH 8.0, 250 mm NaCl,0.[r]

In this study, the antagonistic potential of some native rice specific Trichoderma isolates were evaluated against sheath blight disease of rice caused by Rhizoctonia solani.
