Genetic parameters and indirect selection of elite lines for efficiency in symbiotic nitrogen fixation in black common bean

open access: yesCrop Science, Volume 65, Issue 4, July/August 2025.
Abstract This study aimed to evaluate whether managing populations and progenies of black common bean (Phaseolus vulgaris L.) in exclusive symbiotic nitrogen fixation (SNF) systems, which refer to environments where the primary nitrogen source in the soil is the SNF, is efficient for selecting lines with high symbiotic performance, using grain yield as

Combining abilities and heterotic groups in Pisum sativum L. [PDF]

open access: yes, 2013
The objective of this research was to investigate the use of heterosis and estimates of the general combining ability (GCA) and specific combining ability (SCA) for yield and the yield-related traits for identifying suitable parents and forming heterotic

Quantitative genetic analysis reveals potential to genetically improve fruit yield through selection in Solanum lycopersicum × Solanum pimpinellifolium crosses under humid condition

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract Despite the enormous achievements recorded in tomato (Solanum lycopersicum L.) breeding using traditional and molecular approaches, most cultivars find humid environments highly unfavorable. As a result, fruit production cannot meet the rapidly increasing global demand.

Assessing the utility of genomic selection to breed for durable Ascochyta blight resistance in chickpea

open access: yesThe Plant Genome, Volume 18, Issue 2, June 2025.
Abstract Ascochyta blight (AB) is one of the most devastating fungal diseases of chickpea (Cicer arietinum L.). Conventional breeding has focused on exploiting and introgressing major genes (qualitative effect) to improve AB resistance in released varieties.

Strain comparisons in aquaculture species: a manual [PDF]

open access: yes, 2013
When different strains or breeds of a particular species are available, the best choice is seldom immediately obvious for producers. Scientists are also interested in the relative performance of different strains because it provides a basis for ...

COMBINING ABILITY IN MAIZE LINES USING A DIALLEL CROSS

open access: yesTropical and Subtropical Agroecosystems, 2011
The objective was to select maize (Zea mays L.) lines, based on the effects of general combining ability (GCA), specific combining ability (SCA) and heterosis, for the formation of single crosses.
