QTL mapping through genome-wide association studies (GWAS) is challenging, especially in the case of low heritability complex traits and when few animals possess genotypic and phenotypic information.

The results indicated that for eggplant improvement, additive variation is of great importance and makes it possible to successfully select better individuals in segregating populations, since the selective gains will depend only on gametic variation. For this reason, backcross, pedigree, single-seed descent or gametic selection methods are recommended for advancing the segregating populations.

Due to the advancement in high throughput technology, single nucleotide polymorphism (SNP) is routinely being incorporated along with phenotypic information into genetic evaluation. However, this approach often cannot achieve high accuracy for some complex traits. It is possible that SNP markers are not sufficient to predict these traits due to the missing heritability caused by other genetic variations such as microsatellite and copy number variation (CNV), which have been shown to affect disease and complex traits in humans and other species.

Despite the tremendous therapeutic advances that have stemmed from somatic oncogenetics, survival of some cancers has not improved in 50 years. Osteosarcoma still has a 5-year survival rate of 66%. We propose the natural canine osteosarcoma model can change that: it is extremely similar to the human condition, except for being highly heritable and having a dramatically higher incidence.

The present study was carried out to evaluate fifty wheat genotypes of different ecogeographic origin. Data on eight quantitative characters viz., Plant height, reproductive tillers/plant, length of spike, spikelets/spike, days to maturity, grains/spike, test weight and grain yield/plant were recorded.

The material for the present study consisted of 30 F4 families of bhendi, to assess the genetic components for growth and yield at Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal, UT of Puducherry, India. The mean values and ranges recorded for various traits under study revealed significant variation. The maximum range of variability was observed for fruit yield plant-1 (148.0 to 377.31 g), followed by plant height at final harvest (76.56 to 160.40 cm).

Thirty six diverse genotypes of Indian mustard (Brassica juncea L. Czern and Coss.) were evaluated for ten quantitative. The variability indicates that Genotypic coefficient of variation (GCV) was moderate for 50% flowering, days to maturity, total no. of siliqua per plant, biological weight, test weight and seed yield; low for plant height, no. of siliqua on main shoot, no. of seed per siliqua and harvest index.

In the present investigation, 21 F1s were generated by crossing seven lines and three testers following Line x Tester mating design. Nine yield traits of barley were studied on 21 crosses to estimate heritability in narrow sense, genetic advance in per cent of mean, phenotypic and genotypic coefficient of variation.

Genetic variability, heritability and genetic advance were studied in 22 germplasms of Dolichos beans for yield attributing traits. Analysis of variance revealed significant differences among the genotypes for all the characters studied. For all the characters studied, phenotypic coefficients of variability were higher in magnitude than genotypic coefficients of variability, though difference was very less in majority of the cases.

The experiment was conducted during 2015-2016 at Division of Plant Genetic Resources, Indian Institute of Horticultural Research (IIHR), Hessarghatta, Bengaluru. Genotypic variability, heritability and genetic advance for yield and yield contributing traits were studied on 13 Holostemma ada-kodien accessions. Data were recorded on plant height (m), leaf length (cm), leaf width (cm), petiole length (cm), pedicel length (cm), fruit length (cm), fruit diameter (cm), thickness of pericarp (cm), thickness of mesocarp (cm), number of fruits per plant, fruit yield (kg).
