Abstract Determination of gene effects and combining abilities is a critical stage in maize hybrid breeding. In the present study, 20 S6 lines as female and three S6 inbred lines (K18, K19 and K1264/5-1) as tester were crossed and the resulting  test cross progenies were evaluated in a randomized complete block design with three replications in 2008. During the growing period, several agronomi...

HIGHLIGHTS New parthenocarpic gynoecious cucumber line ‘PBRK-11’ was developed and characterized. Application of silver thiosulphate @ 250 ppm induced maximum number male flowers per plant, minimum plant mortality percentage for longer duration. In vitro protocol standardized to maintain the inbred “PBRK-11”.

VER nearly half a century numerous workers have considered covariances and/or correlations between genotypic values of relatives and have related these population parameters to more basic parameters descriptive of the Mendelian mechanism of inheritance for diploids and the modes of gene action. FISHER (1918) considered random mating populations and developed formulae for the correlations betwee...

In their quest to elucidate the genetic influences contributing to alcoholism, researchers have long used selected lines and inbred strains of rodents. Selected lines are obtained by repeatedly mating those animals within a population that show extremely high or low values of the desired trait. Inbred strains are generated by mating male and female siblings, irrespective of any particular trait...
