Identification and Validation of Quantitative Trait Loci for Grain Number in Rice (Oryza sativa L.)

Agronomy, 2020
Grains number is one of the most important agronomic traits in the determination of rice productivity. To explore the underlying genetic basis of grain number in rice, quantitative trait locus (QTL) analysis was performed using three recombinant inbred ...

Multi-environment QTL mixed models for drought stress adaptation in wheat [PDF]

, 2008
Many quantitative trait loci (QTL) detection methods ignore QTL-by-environment interaction (QEI) and are limited in accommodation of error and environment-specific variance.

Serious limitations of the QTL/Microarray approach for QTL gene discovery [PDF]

BMC Biology, 2010
Abstract Background It has been proposed that the use of gene expression microarrays in nonrecombinant parental or congenic strains can accelerate the process of isolating individual genes underlying quantitative trait loci (QTL). However, the effectiveness of this approach has not been assessed.

Development of single nucleotide polymorphism markers and genetic diversity in guava (Psidium guajava L.)

PLANTS, PEOPLE, PLANET, Volume 5, Issue 1, Page 58-69, January 2023., 2023
There are many understudied fruits of great economic and productive importance for regional agricultural hubs. Guava is an American fruit species with attractive nutritional and adaptability characteristics. However, in many countries like Mexico, its cultivation is still limited to small‐to‐medium size plantings and home gardens and depends on poorly ...

Multiple QTL for horticultural traits and quantitative resistance to Phytophthora infestans linked on Solanum habrochaites chromosome 11. [PDF]

, 2014
Previously, a Phytophthora infestans resistance QTL from Solanum habrochaites chromosome 11 was introgressed into cultivated tomato (S. lycopersicum). Fine mapping of this resistance QTL using near-isogenic lines (NILs) revealed some co-located QTL with ...

Epistatic modifiers influence the expression of continual flowering in strawberry

PLANTS, PEOPLE, PLANET, Volume 5, Issue 1, Page 70-81, January 2023., 2023
Until the 1970s, the majority of commercial strawberry varieties produced a single bloom of flowers. However, continuously flowering, everbearing strawberries are now routinely cultivated and use is increasing. Indeed, introgression of the everbearing flowering trait can lead to economic benefits for growers through the production of a continual crop ...

Quantitative trait loci for bone traits segregating independently of those for growth in an F-2 broiler X layer cross [PDF]

, 2007
An F broiler-layer cross was phenotyped for 18 skeletal traits at 6, 7 and 9 weeks of age and genotyped with 120 microsatellite markers. Interval mapping identified 61 suggestive and significant QTL on 16 of the 25 linkage groups for 16 traits.

Breeding and selection of taro (Colocasia esculenta) for improved disease‐resistance in Hawaiʻi

PLANTS, PEOPLE, PLANET, Volume 5, Issue 1, Page 123-145, January 2023., 2023
Taro is a root crop with wide geographic range and high cultural significance to Indigenous peoples of Hawaiʻi and the Pacific. Taro Leaf Blight (TLB) is a worldwide disease of taro, and Hawaiian taro varieties exhibited little resistance to it. To improve TLB‐resistance, conventional breeding was conducted by hand‐pollination.

Bayesian multi-QTL mapping for growth curve parameters [PDF]

, 2010
Background Identification of QTL affecting a phenotype which is measured multiple times on the same experimental unit is not a trivial task because the repeated measures are not independent and in most cases show a trend in time. A complicating factor is

In silico Analysis of qBFR4 and qLBL5 in Conferring Quantitative Resistance Against Rice Blast

Journal of Pure and Applied Microbiology, 2018
The devastating yield losses caused by rice blast can be mitigated by breeding resistant cultivars with QTLs enriched with resistance (R-gene) and defence related genes. These genes are the arsenal of the plant’s immune system against pathogen invasion.
