Direct high positive association

The detection of signatures of selection in genomic regions provides insights into the evolutionary process, enabling discoveries regarding complex phenotypic traits. In this research, we focused on identifying genomic regions affected by different selection pressures, mainly highlighting the recent positive selection, as well as understanding the candidate genes and functional pathways associated with the signatures of selection in the Mangalarga Marchador genome.

The exploitation of yield potential through inter sub specific (inter-racial) hybridization become a challenging task for rice breeders. Grain yield improvement is considered to be prime objective of any breeding programme, quality traits are yet another important consideration of rice breeding in India. Association of yield and yield components and among grain quality traits thus assumes a unique prominence as the basis for selecting desirable high yielding genotypes with good grain quality characters.

Correlation and path analysis were carried out in forty-five tomato hybrids along with ten parents for yield. The association studies showed that fruit yield per plant was positively and significantly correlated with average fruit weight. However, fruit yield per plant was negatively correlated with number of cluster per plant, length of fruits, total number of branches per plant, TSS and ascorbic acid content of fruit.

Yield is a complex character controlled by a large number of contributing characters and their interactions. For any effective selection programme, it would be desirable to consider the relative magnitude of association of various characters with yield. The path coefficient technique helps in estimating direct and indirect contribution of various components in building up the total correlation towards yield.

Chickpea is a cool season pulse and suffers severe yield losses when exposed to higher temperatures during reproductive phase. Stable chickpea production will depend on the release of new cultivars with improved adaptation to drought and high temperature. Twenty five breeding lines of two crosses JG 11 x JG 14 and JAKI 9218 x JG 14 were assessed under timely and late sown situations. High variability was observed for majority of the traits in both the seasons.
