Genetic analysis of root traits in maize

Genetic Analysis of Kernel Traits in Maize-Teosinte Introgression Populations

Seed traits have been targeted by human selection during the domestication of crop species as a way to increase the caloric and nutritional content of food during the transition from hunter-gather to early farming societies. The primary seed trait under selection was likely seed size/weight as it is most directly related to overall grain yield. Additional seed traits involved in seed shape may ...

Genetic Diversity Analysis of Maize Hybrids Through Morphological Traits and Simple Sequence Repeat Markers

Comparing different methods of estimating the genetic diversity could define their usefulness in plant breeding programs. In this study, a total of 18 morphological traits and 20 simple sequence repeat (SSR) loci were used to study the morphological and genetic diversity among 20 maize hybrids selected from different countries, and to classify the hybrids into groups based on molecular profiles...

QTL mapping for maize root system traits

Genetic Evaluation of Root Complexity in Maize

Root architecture is strongly linked to plant survival under abiotic and biotic stress conditions. The objective of this study was to investigate the inheritance of the primary root system complexity in maize (Zea mays L.). For a total of 231 recombinant inbred lines (RIL) derived from the IBM (B73×Mo17) population multiple primary root systems were produced by applying a replicated alpha latti...

From Qtls to Genes Controlling Root Traits in Maize

In maize, two major quantitative-trait loci (QTLs) on chromosome bins 1.06 and 2.04 have been shown to affect root architecture and a number of agronomic traits, including grain yield. The QTL on bin 2.04 (root-ABA1) also affects root lodging and ABA concentration in the leaf. To evaluate the effects of root-ABA1 better, near-isogenic lines (NILs) have been produced and evaluated per se and in ...
