Combining ability and genetic divergence among tropical maize inbred lines using SSR markers

چکیده
Our objectives were to evaluate general and specific combining ability (SCA) genetic divergence among tropical maize inbred lines using single sequence repeat (SSR) markers. Thirteen crossed based on a complete diallel scheme. Hybrids three checks evaluated in lattice experimental design. Silk anthesis flowering, average plant height, ear white spot (Pantoea ananatis) gray leaf (Cercospora zeae-maydis) severity, grain yield evaluated. Significant differences (p < 0.05) for abilities observed all traits. Based additive effects, 1 (Flash) 12 (SG 6015) selected reduce the flowering period height. Inbred 2 (CD 303) 3 (AG 8080) disease severity. For simultaneous increase reduced severity of diseases, line 11 9090) as parent or tester topcross schemes is recommended. According non-additive crosses × 13 (DKB 747) future breeding programs. Six groups identified SSR markers; major group contained six lines. Because minor relationship between SCA effects limits, use divergent

Genetic Distance Based on SSR Markers and Testcross Performance of Maize Inbred Lines
The identification of parental inbred lines to develop superior hybrids is a rather costly and time-consuming step in maize breeding. In some cases, pedigree information has been used to select diverse parental lines. In the case of Iranian maize inbred lines, this information is not fully available. In this study we investigated the genetic distance (GD) based on Simple sequence Repeats (SSR) ...
متن کاملCombining Ability among Twenty Insect Resistant Maize inbred lines Resistant to Chilo partellus and Busseola fusca Stem borers
A partial diallel design was used among 20 maize inbred lines to form 110 F1 hybrids to generate information on the values of these lines for developing insect resistant maize varieties during the short rains season of 2006. The hybrids were evaluated for resistance to the C. partellus and B. fusca, and for agronomic performance over two seasons during long and short rains of 2007 at a mid-alti...
متن کاملCombining ability of tropical and temperate inbred lines of popcorn.
In Brazil, using combining ability of popcorn genotypes to achieve superior hybrids has been unsuccessful because the local genotypes are all members of the same heterotic group. To overcome this constraint, 10 lines (P(1) to P(10)) with different adaptations to tropical or temperate edaphoclimatic environments were used to obtain 45 F(1) hybrids in a complete diallel. These hybrids and three c...

متن کاملGenetic diversity of African maize inbred lines revealed by SSR markers.
Knowledge of genetic diversity (GD) and relationships among maize inbred lines is indispensable in a breeding program. Our objectives were to (1) investigate the level of genetic diversity among maize inbred lines and (2) assess their genetic structures by applying simple sequence repeat (SSR) markers. Fifty-six highland and mid-altitude maize inbred lines obtained from CIMMYT programs in Ethio...
