Molecular markers have been utilized for genetic diversity, phylogenetic analysis, germplasm evaluation, genome mapping, genetic linkage map construction and marker-assisted selection to investigate structural genomics in crop plants (Muthamilarasan and Prasad, 2015).

Preponderance of wood apple seedlings are seen growing naturally at scattered/isolated areas of various agro climatic zones of Gujarat, India, and chance for the selection of superior genotypes are very high due to huge genetic diversity in the exiting populations. In order to reveal the genetic variability in wood apple, as fruit sample with shoot from diverse areas of province were collected and analysed for various physic-chemical attributes.

Characterization of cultivars using bio-chemical markers has been successfully used for selection of improved cultivars in mango for breeding programs. The study was conducted at Horticultural research station, Venkataramannagudem for evaluating the variability of mango cultivars to conserve the elite ones and to identify the superior genotypes based on fruit bio-chemical markers for future crop improvement. Thirty four cultivars were characterized using bio-chemical fruit markers in subsequent years to know the genetic diversity in mango.

The present investigation was carried out with 32 diverse genotypes of bread wheat in completely randomized block design with 3 replications at Norman E. Borlaug Crop Research Centre, G.B. Pant University of agriculture & Technology Pantnagar for screening the genetic diversity for yield and physiological traits under normal sown condition. The observations were recorded on 16 agronomic traits and 3 physiological traits. The statistical analysis for genetic divergence was done using Mahalanobis-D 2 statistics and clustering of genotypes was done using Tocher method.

Chilli leaf curl disease is a serious threat to summer crop of chilli in South India causing economic yield losses. Therefore, development of chilli hybrids having leaf curl tolerance and high yield is the present need in chilli growing regions. Seven high yielding lines were crosses with four resistant testers in line × tester mating design to produce 28 F1 hybrids. Highest heterosis over better parent was exhibited by the cross L6 × T4 for fruit length (74.71%), by L4 × T3 for fruit girth (37.58%), by L6 × T1 for fruits plant-1 (37.86%), by L1 × T2 for fruit weight (51.

Berseem, a nitrogen-fixing, annual, multicut forage crop cultivated around 2 million hectares areas of northern, central and eastern parts of India. Berseem has variability for pollination behavior however variation for morphological and agronomic traits are scare, perhaps, because of initially introduction of crop with narrow genetic base. Genetic variability have been fortified through introduction of exotic materials, intra-interspecific hybridization, induction of polyploidy and mutation. ICAR-Indian Grassland and Fodder Research Institute maintain >900 accessions of Trifolium spp.

Perennial fruit crops generally and temperate fruits in particular make an important contribution to the sustainable development of the socio-economy in the northern mountainous region of Vietnam where the living standard of local farmers - 40% of whom are minorities from 30 groups - is still low (about 70% of the average of the country as a whole), though significant assistance has been made by the government and a slowly developed socio-economy has been recorded.

When animals are selected from farmers’ herds, ideally farmers involved in the selection programme will have several cows, so that animals can be compared both within and across herds. When purchasing bull calves or females for future bulls, AI service providers have to consider the production and reproduction records, general appearance, breed makeup and pedigree performance of the cow. The most accurate way to select the best cows will be to perform a statistical analysis to obtain a genetic evaluation. Many factors other than genetics will affect an animal’s production.
