Studies on maize inbred lines susceptibility to herbicides

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) ...

Increasing Kernel Density for Two Inbred Lines of Maize

Improving grain quality of maize (Zea mays L.), including endospermhardness and density, is often a breeding objective.Dense seed is preferred by dry millers and for alkaline processing, and can command a price premium at market. This study attempted to increase kernel density in a backcrossing program for two inbreds of maize using two selection techniques, specific gravity of kernels and the ...

Variability among maize inbred lines for seed longevity

Genetic Diversity in Maize (Zea mays L.) Inbred Lines

Thirty yellow inbred lines of normal maize were evaluated for thirteen parameters at the experimental field of Hajee Mohammad Danesh Science and Technology University during 2010-11 to study the genetic divergence using multivariate analysis. The thirty inbreds fell into six distinct clusters. The intra-cluster distances in all the six clusters were more or less low, indicating that the genotyp...

SSR Variation in Important U.S. Maize Inbred Lines

that some of the inbreds continued to contribute substantially to hybrids marketed in the USA. For example, Historically important public inbred lines continue to play an imB73 and Mo17 were used in about 28% of all seed portant role in maize (Zea mays L.) improvement in many different breeding programs. Their continued use means they have undergone planted in the USA in 1979. This fell to 12.8...
