Genetic loci mapping associated with maize kernel number per ear based on a recombinant inbred line population grown under different nitrogen regimes.
Kernel number per ear (KNE) is one of the most important yield-related agronomic traits in maize (Zea mays). To clarify its genetic basis, we made a quantitative trait locus (QTL) analysis of KNE in a recombinant inbred line population derived from lines Mo17 and Huangzao4, under two nitrogen (N) regimes. Seven QTLs, on chromosomes 4, 6 and 9, were mapped under the high N regime, which ex...
متن کاملGenetic loci mapping for ear axis weight using recombinant inbred line (RIL) population under different nitrogen regimes in maize
Ear axis weight (EAW) is one of the important agronomic traits in maize (Zea mays L.), related to yield. To understand its genetic basis, a recombinant inbred line (RIL) population, derived from the cross Mo17 × Huangzao4, was used for quantitative trait locus mapping (QTL) for EAW under high and low nitrogen (N) regimes. The results showed that a total of three QTLs were mapped on chromosomes ...
متن کاملQuantitative trait locus analysis for ear height in maize based on a recombinant inbred line population.
Maize (Zea mays L.) is among the crops with the greatest worldwide economic importance. Ear height is a very important trait that is considered necessary in maize and is related to morphology, lodging, and yield. To realize its genetic basis, an F9 recombinant inbred line population and a genetic map consisting of 101 simple sequence repeat markers were used to detect the quantitative trait loc...
متن کاملQTLs for days to silking in a recombinant inbred line maize population subjected to high and low nitrogen regimes.
Days to silking (DTS) is one of the most important traits in maize (Zea mays). To investigate its genetic basis, a recombinant inbred line population was subjected to high and low nitrogen (N) regimes to detect quantitative trait loci (QTLs) associated with DTS. Three QTLs were identified under the high N regime; these explained 25.4% of the phenotypic variance. Due to additive effects, t...
متن کاملQTL identification of ear leaf morphometric traits under different nitrogen regimes in maize.
The ear leaf is one of the most important leaves in maize (Zea mays); it affects plant morphology and yield. To better understand its genetic basis, we examined ear leaf length, ear leaf width, and ear leaf area for quantitative trait locus (QTL) mapping in a recombinant inbred line population under two nitrogen regimes. Nine QTLs, on chromosomes 1 (one), 2 (one), 3 (one), 4 (three), 7 (one), a...
