abstract

pod borer is one of the main factors for yield decrease of chickpea. therefore, breeding of chickpea for resistance to this pest is important. modified cry1ac gene of bacillus thuringiensis in pcry1ac-nptii plasmid containing twin t-dna for cry1ac and nptii genes have been used for transformation of chickpea. at last 38 plants had nptii gene that 36 plants of them had cry1ac gene and two plants had only nptii gene. western blotting analysis showed that 30 plants had cry1ac protein expression. transformation percentage was 0.37 in this experiment. only 7 plants produced t1 seeds. regarding to western blotting and pcr analysis for t0 and t1, plants were devided to some groups with different expressions. bioassay with neonate of pod borer showed high mortality in lines with high cry1ac protein expression.

Expression of a Chimeric Gene Encoding Insecticidal Crystal Protein Cry1Aabc of Bacillus thuringiensis in Chickpea (Cicer arietinum L.) Confers Resistance to Gram Pod Borer (Helicoverpa armigera Hubner.)

Domain swapping and generation of chimeric insecticidal crystal protein is an emerging area of insect pest management. The lepidopteran insect pest, gram pod borer (Helicoverpa armigera H.) wreaks havoc to chickpea crop affecting production. Lepidopteran insects were reported to be controlled by Bt (cryI) genes. We designed a plant codon optimized chimeric Bt gene (cry1Aabc) using three domains...

Genetics of traits associated with pod borer resistance and seed yield in chickpea (Cicer arietinum L.)

The combining ability analysis using Line × Tester model was conducted in chickpea to know the general and specific combining ability of the distingushing parents and their crosses, respectively and to select best material for further breeding programme and generation advanceme- nt. Two genetically diverse testers viz., JAKI-9218 and ICCV-2 as females and 8 males viz., HC-5, ICC-506, PKV Harita...

GENETIC DIVERGENCE IN CHICKPEA (Cicer arietinum L.)

Genetic diversity of 27 chickpea genotypes was studied through Mahalanobis D and Principal Component analysis. The genotypes under study fall into five clusters. The cluster II contained the highest number of genotypes (11) and Cluster I contained the lowest. Cluster I produced the highest mean value for number of pods per plant. The inter cluster distances were much higher than the intra clust...

Efficacy of Some Synthetic and Biopesticides Against Pod Borer, Helicoverpa armigera (Hubner) in Chickpea

Efficacy of some synthetic and biopesticides against pod borer, Helicoverpa armigera (Hubner) damage in chickpea was studied at the Regional Agricultural Research Station, Ishurdi, Pabna, Bangladesh during rabi cropping season of 2004-05. Synthetic and biopesticides reduced pod borer damage significantly. Significantly lowest pod damage was observed in cypermethrin (5.75%) and HNPV (5.86%) spra...

Investigating The Genetic Resistance of Some Iranian Chickpea (Cicer arietinum L.) Cultivars to Pursuit Herbicide

Chickpea (Cicer arietinum L.) is one of the most important crops in the world. After bean and pea, chickpea is the most important cold season legume. Weeds are one of the most important threats to chickpea production worldwide. Due to the sensitivity of chickpea to herbicides, the majority of herbicides are used pre-emergence and the use of post-emergence herbicides is limited, and therefore we...
