Combining Ability for Yield and Yield Components in Groundnut (Arachis hypogaea L.)

Combining Ability of Pod Yield and Related Traits of Groundnut (Arachis hypogaea L.) under Salinity Stress

A study was performed using 6 × 6 F1 diallel population without reciprocals to assess the mode of inheritance of pod yield and related traits in groundnut with imposed salinity stress. Heterosis was found for pod number and yield. Data on general and specific combining ability (gca and sca) indicated additive and nonadditive gene actions. The gca: sca ratios were much less than unity suggesting...

Gene effects of pod yield and its components in three crosses of groundnut ( Arachis hypogaea L . )

1415 Research Article Gene effects of pod yield and its components in three crosses of groundnut (Arachis hypogaea L.) Abstract: Groundnut, (Arachis hypogaea L.) is a major source of vegetable oil and protein and also a major source of fodder crop. Genetic systems that control the expression of quantitative traits facilitate the choice of the most efficient breeding and selection procedure. Gen...

Phylloplane bacteria increase seedling emergence, growth and yield of field-grown groundnut (Arachis hypogaea L.).

AIM To isolate and characterize groundnut-associated bacterial isolates for growth promotion of groundnut in field. METHODS AND RESULTS Three hundred and ninety-three groundnut-associated bacteria, representing the geocarposphere, phylloplane and rhizosphere, and endophytes were applied as seed treatment in greenhouse. Maximum increase in plant biomass (up to 26%) was observed following treat...

GENETIC DIVERGENCE IN GROUNDNUT (Arachis hypogaea L)

Comprising 34 groundnut genotypes an experiment was conducted in a randomized block design with three replication at the Research farm of Regional Agricultural Research Station, BARI, Hathazari, Chittagong during Rabi season (December 2009 to April 2010) for estimation of the multivariate analysis of divergence. The genotypes were grouped into five clusters. Cluster III contained the highest nu...
