  Out of 262 swab samples from feet of clinically footrot affected sheep from Jammu and Kashmir, 135 (52.0%) detected positive for Dichelobacter nodosus by 16S rRNA gene specific PCR. Out of these135 positive samples, 82 (61.74%) tested positive for intA gene carried by virulent strains. A mulplex PCR for simultaneous detection and virulence characterization of D. nodosus in clinical samples was therefore devised. The test detected 77 (57.03%) samples positive for virulent D. nodosus. The results were comparable and the success of the multiplex PCR was established. Out of 30 randomly selected isolates subjected to gelatin gel test, 24 isolates with intA gene produced thermostable protease while six isolates without intA gene revealed the production of thermolabile protease. This indicated a good co-relation between presence of intA gene and gelatine gel test in determination of the D. nodosus virulence.

  This study has been conducted to determine the extent of genetic association between yield of Rice (Oryza sativa L.) and its components. The present experiment was carried out with 40 Rice (Oryza sativa L.) genotypes which were evaluated in a randomized block design with 3 replications during wet season of 2007 and 2008. Results showed that sufficient amount of variability was found in the entire gene pool for all traits studied. Higher magnitude of genotypic and phenotypic coefficients of variation was recorded for seed yield, harvest index, biological yield, number of spikelets per panicle, flag leaf length, plant height and number of tillers indicates that these characters are least influence by environment. High heritability coupled with high genetic advance as percent of mean was registered for seed yield, harvest index, number of spikelets per panicle, biological yield and flag leaf length, suggesting preponderance of additive gene action in the expression of these characters. Grain yield was significantly and positively associated with harvest index, number of tillers per hill, number of panicle per plant, panicle length, number of spikelet's per panicle and test weight at both genotypic and phenotypic levels. Path coefficient analysis revealed that harvest index, biological yield, number of tillers per hill, panicle length, number of spikelets per panicle, plant height and test weight had direct positive effect on seed yield, indicating these are the main contributors to yield. From this study it may be concluded that harvest index, number of tillers per hill, panicle length and number of spikelet per panicle and test weight are the most important characters that contributed directly to yield. Thus, these characters may serve selection criteria for improving genetic potential of rice.
