The experiment was conducted at NBPGR Regional Station, Rajendranagar during 2013-14 (August 2013 to February 2014) to study the genetic variability and association among the quality characters in jack bean. The results revealed that significant variation was observed for all the characters. Among the characters studied, the highest heritability coupled with genetic advance as percent of mean was observed for magnesium followed by calcium and iron contents. However, heritability alone was found to be highest for iron content followed by magnesium, calcium and protein contents. Calcium content had significant positive association with protein content whereas magnesium, calcium and iron content recorded the positive direct effect on protein content while sodium content have negative effect.

Four Blocks

The present investigation was undertaken to assess the genetic variability and character associations for seed yield and component characters in 307 soybean germplasm lines. The lines were raised in augmented block design in four blocks during kharif 2014. Out of these, twenty seven promising genotypes were selected and forwarded for evaluation along with four checks in randomized block design with three replications at CSKHPKV, Palampur (H.P) during kharif 2015. The analysis of variance revealed the presence of sufficient genetic variability in the breeding material. High PCV and moderate GCV were recorded for harvest index and biological yield/plant. High heritability coupled with high genetic advance were observed for harvest index followed by biological yield /plant, seed yield /plant, number of pods/plant and 100-seed weight indicating the predominance of additive gene action in controlling the trait. Number of branches /plant, number of seeds /pod, biological yield/plant and harvest index exhibited significantly positive correlation with seed yield /plant both at phenotypic and genotypic levels. Two traits viz., harvest index and biological yield /plant could be considered as direct selection indices for yield improvement in soybean.

The purpose of the study described in this Research Communication was to report the full characterisation of the goat and sheep oxytocin-neurophysin I gene (OXT), their promoters and amino acid sequences. Using the genomic DNA as template, we sequenced and compared the whole OXT gene (3 exons), plus 958/960 nucleotides at the 5′ flanking region and 478/477 nucleotides at the 3′ flanking region, in 46 sheep and 24 goats belonging to different breeds/genetic types reared in Italy, Greece and Germany. The comparison of the obtained sequences showed a high degree of genetic variability at these loci. In particular, we focused on the SNP g.438T > C as possible example of trans-specific polymorphism. This SNP alters a putative binding site of the transcription factor Oct-1. The set-up of a luciferase assay confirmed that the C variant of this SNP negatively affects the promoter activity of the sheep OXT gene. The results of this study suggest that the SNP g.438T > C might be useful to promote association studies with traits/physiological processes controlled by this hormone.
