Estimates of combining ability and standard heterosis for grain yield and various agromorphological traits in rice (Oryza sativa L.) [PDF]
Journal of Applied and Natural Science, 2017 A study was conducted for estimating combining ability and standard heterosis for grain yield and various agromorphological traits involving 10 parents and their 45 F1s (half diallel) during 2012-13 and 2013-14. The results of present investigation revealed that additive gene action played a predominant role in the inheritance of most of the traits ...

Standard heterosis and trait association of maize inbred lines using line x tester mating design in Ethiopia [PDF]
African Journal of Plant Science, 2020 Maize is one of the high priority crops to feed the ever increasing population in Africa, however, its production limited by shortage of high yielding variety coupled with biotic and abiotic stresses. The study was initiated to evaluate the heterotic performances of the F1 hybrids over the standard checks (Kolba and Jibat). Fifty entries consists 48 F1

Bangladesh Journal of Plant Breeding and Genetics, 2015 An experiment was carried to estimate heterotic performances of newly developed test hybrids utilizing CMS system during Rabi 2011 using RCBD design. Five known CMS lines and sixteen developed R-lines were crossed through line × tester analysis. Eighty test hybrids were developed.

EAS Journal of Biotechnology and Genetics, 2022 For an organized cross breeding program, information on heterotic grouping, perse performance, and commercial heterosis of newly introduced maize lines is required. Therefore, the present study was conducted to determine the heterotic group, commercial heterosis, perse and crosses mean performance of newly introduced from IITA-Nigeria and CIMMYT ...

Studies of standard heterosis for quantitative traitsin eggplant (Solanum melongena L.)
INTERNATIONAL JOURNAL OF AGRICULTURAL SCIENCES, 2016 Standard heterosis has been amply exploited in developing hybrids in eggplant by increasing commercial value of them. In an experiment, fifteen parents (12 lines and 3 testers) were selected on the basis of divergence and mated them in line x tester design. Hybrids and parents rose to measured heterosis for different quantitative traits.
