Genetic footprint of population diversity and genetic structure of infecting apple (Malus × domestica Borkh.).

Unlabelled: Apple scab instigated by impels remarkable losses to apple fruit production. In an effort to comprehend the key mechanisms of evolutionary potential defining population, 132 isolates of from five commercial apple orchards were collected and assayed using 14 microsatellite markers. The average diversity was observed within the individuals of populations based on the Shannon-Wieners index (I) and observed heterozygosity (Ho) was average but considerably lower than expected heterozygosity (He).

DNA marker based diversity across rice genotypes and advanced breeding lines bred for temperate regions of North-West India.

Background: Characterization and evaluation of plant genetic resources play an important role for their utilization in the crop improvement programmes.

Methods And Results: This study involves the agro-morphological and cooking quality besides, molecular characterization of 51 genotypes/advance breeding lines of rice from Kashmir Himalayas. Significant variability was observed for all agro-morphological and cooking quality traits among all the studied genotypes.
