Abstract Undesirably low oleic acid and high linoleic acid concentrations in seed oil are typical of Valencia peanuts (Arachis hypogaea L.) produced in a cool, short-season climate. Improved oil quality may be achieved by incorporating Virginia type germplasm into adapted Valencia peanuts. The objectives of this study were to determine the oil quality of nine Valencia and four Virginia peanut lines, evaluate their combining ability for oil concentration, fatty acid composition of the oil, and several taxonomic characters, and assess the potential for developing cultivars adapted to Ontario with improved oil quality. General combining ability (GCA) of the Virginia parents significantly exceeded specific combining ability (SCA) for all fatty acids except arachidic, and also for oleic/linoleic (O/L) ratio, days to first flowering, days to full flowering, and branching pattern (R/R + V ratio). GCA of the Valencia parents significantly exceeded SCA only for oil concentration. Significant SCA estimates were found for oil concentration, palmitic and oleic acids, O/L ratio, and height of the main axis (first date). Significant heterosis was detected for all taxonomic characters except days to first flowering. Genetic variability for all characters except arachidic acid indicates that the development of Ontario cultivars with improved oil quality, in terms of higher oil content and reduced linoleic acid levels, appears feasible through breeding efforts.

In groundnut during Rabi 2015-16 Combining ability and heterosis was studied among 9 crosses involving three diverse lines viz., IVK 2015-21, IVK 2014-21and ICGV 00348 and 3 testers viz., Kadiri 7, Kadiri 6 and JCG 2141.On the basis of per se performance and General Combing Ability (GCA) effects together, the parents IVK-2014-21 and Kadiri-7 were identified as better combiners for various yield and its attributing characters. These parental materials could be better utilized as valuable basic material in developing high yielding groundnut varieties. Among those, based on per se performance, the corresponding GCA status of parents and SCA effects for most of the yield traits viz., days to 50% flowering, days to maturity, 100 kernel weight and pod yield per plant only one cross viz.,IVK14-21 x K7 was considered as better one.

Groundnut (Arachis hypogaea L.) is the world’s third important source of oil. A Genomic Selection Training Population (GSTP) comprising 340 genotypes was evaluated over four locations for two seasons to study genetic variability and association among agronomical and quality traits. GSTP exhibited significant variation among the genotypes, seasons and G x E interaction. Moderate to high magnitude of genotypic coefficient of variation and phenotypic coefficient of variation coupled with high heritability was observed for most quality traits. The first 7 components of PCA analysis contributed more than 75% cumulative variability. The training population grouped into three clusters in both the seasons. The number of pods/plant, pod and seed yield/plant were significantly and positively associated with each other, while test weight had negative association with number of pods/plant and had positive association with pod and seed yield during rainy season of 2015. The significant positive correlation was also observed between oil, linoleic acid and stearic acid; similarly, linoleic acid had positive association with stearic acid and palmitic acid. Significant negative correlation was observed between oil and protein content, oleic acid and linoleic acid content. The superior genotypes, namely, ICG 5221, ICGV 01393, ICGV 07220, ICGV 97120, ICGV 06420, ICG 9507, ICGV 06188 and ICGV 00440 were best performer for yield, yield components and nutritional quality traits while ICG 2381 and ICG 5221 recorded a better performance for oil content. The rainy season was found to have an advantage for vegetative, physiological growth, oil content, oleic and oleic to linoleic ratio while the post-rainy season led to forced pod filling and reduced maturity.
