Advances in genomics technologies are making it increasingly feasible to characterize breeding lines that carry traits of agronomic interest. Tobacco germplasm lines that carry loci designated VAM and va have been extensively investigated due to their association with potyvirus resistance (both VAM and va) and defects in leaf surface compounds originating from glandular trichomes (VAM only). Molecular studies and classical genetic analyses are consistent with the model that VAM and va represent deletion mutations in the same chromosomal region.

Genetic diversity among 30 advanced breeding lines of groundnut were estimated using Mahalanobis D2 statistic for 21 characters. The analysis of variance revealed significant differences among the advanced breeding lines for all characters. Based on Tocher's method, 30 advanced breeding lines were grouped into ten clusters.

The genetic diversity and gene pool characteristics must be clarified for efficient genome-wide association studies, genomic selection, and hybrid breeding. The aim of this study was to evaluate the genetic structure of 509 wheat accessions representing registered varieties and advanced breeding lines via the highdensity genotyping-by-sequencing approach.

At the same time, the breeding lines from the advanced generations are also used as parental lines for developing commercially exploitable heterotic hybrids. But, most often the source of early generations i.e., F3, F4, F5 and F6 segregating populations offer wider opportunities for achieving high success, because of wider genetic base.

In this context, genetic resistance remains the most economical method for the resource poor farmers. So far, the released varieties are found to be susceptible to GBND. Identification of GBND resistant sources in newly developed advanced breeding lines which are agronomically superior would help in recommending and release of these genotypes for GBND endemic locations. Keeping in view the economic importance of the disease in most of the groundnut growing areas and lack of available resistance sources to GBND, present work has been taken up.

Genetic divergence of 100 sesame (Sesamum indicum L.) advanced breeding lines was assessed using Mahalanobis's D2 method and the lines were grouped into 12 clusters. Cluster-I was the biggest with 76 genotypes followed by cluster-III with 14 genotypes. Ten clusters (Cluster II, IV, V, VI, VII, VIII, IX, X, XI, XII) were solitary in nature.

A field experiment was conducted in Rabi 2015 in a randomized block design with the objective to screen advanced breeding lines (genotypes) of Indian mustard (Brassica juncea L. Czern and Coss) for different physiological parameters viz, chlorophyll content, membrane stability index (MSI %), relative water content (RWC %) and electrolyte leakage and yield related to terminal heat tolerance. The study indicated that genotypes, ‘Pusa Bold’, ‘NRCHB-101’ and ‘PRO-5222’ had tolerance to high temperature at terminal stage.

The use of transferable cross-species/genera SSR markers is an alternative strategy to ensure availability of markers in genomic resources-limited crops such as dolichos bean. A total of 275 cross legume species/genera SSR markers were examined for their transferability to dolichos bean.

The study revealed that flower color and hypocotyl pigmentation could be used as critical morphological characters for ascertaining varietal distinctiveness amongst genotypes. Of the 22 genotypes, few were utterly unique as they could be distinguished based on a single trait while the majority were very closely related. Cluster analysis revealed that the 22 genotypes could be grouped into four major clusters, whereby 13 genotypes were found to be unique based on at least one character and others could be distinguished based on a set of traits rather than a single trait.

Leaf spots are the most serious foliar fungal diseases of groundnut (Arachis hypogaea L.) World wide. Early leaf spot and late leaf spots, singly or together can cause losses in pod yield of over 50% and reduce the quality of the pod and fodder. Screening of genotypes and advance breeding lines is one of the primary objective for resistance breeding in groundnut. Present investigation was carried out to screen 33 advance breeding lines and 7 released varieties of groundnut against early and late leaf spot diseases.

The extent of variability and heritability of the characters among the genotypes is the basic source for the exploitation of superior potentiality of genotypes. Calculation of GCV and PCV will gives the extent of environmental influence on the traits, whereas heritability gives the information on the magnitude of inheritance of quantitative traits, while genetic advance will be helpful in formulating suitable selection procedures.

Understanding the genetic variability and diversity of a crops species provides opportunity for plant breeders to develop new and improved cultivars having both farmer-preferred and breeder-preferred traits. In the present study 11 morphological characters and 16 quantitative characters were recorded from 27 advance breeding lines/varieties to identify useful alleles for future breeding. Genotypes varied considerably in plant growth and morphological characters. The overall mean of ShannonWiener diversity index (H’) value was 0.
