QTL mapping of spike fertility index in bread wheat

Crop Breeding and Applied Biotechnology, 2021
Spike fertility index (SF) is a trait easily measured at maturity and strongly associated with the number of grains per unit area. In order to identify genomic regions involved in SF control, a biparental (Baguette 10 × Klein Chajá) population of 80 ...

Modeling missing pedigree in single-step genomic BLUP [PDF]

Journal of Dairy Science, 2019
The objective was to compare methods of modeling missing pedigree in single-step genomic BLUP (ssGBLUP). Options for modeling missing pedigree included ignoring the missing pedigree, unknown parent groups (UPG) based on A (the numerator relationship matrix) or H (the unified pedigree and genomic relationship matrix), and metafounders.

Introgressed Variation in TaMYB7‐A1 Drives Graded Dormancy and Climate‐Adaptive Pre‐Harvest Sprouting Resistance in Wheat

Advanced Science, EarlyView.
TaMYB7‐A1 directly activates TaABI5 to enhance ABA signaling and regulate ABA‐GA homeostasis, enforcing seed dormancy. Its superior allele, derived from wild einkorn introgression, harbors a MITE insertion that elevates expression and two amino acid substitutions that enhance transcriptional activity, collectively generating graded PHS resistance for ...

Genomic selection for nitrogen use efficiency in perennial ryegrass (Lolium perenne L.) under field conditions

Grassland Research, EarlyView.
There is genetic variation in ryegrass for the ability to respond to nitrogen fertilizer, Breeding nitrogen use efficient cultivars can increase farm profitability and sustainability. Abstract Background Improving the nitrogen use efficiency (NUE) of pastures has the benefit of reducing costs of production and reducing nitrogen loss to the environment.

Breeding switchgrass for reduced nitrogen demand

Grassland Research, EarlyView.
Breeding has improved switchgrass biomass yield, but productivity is still heavily dependent on nitrogen fertilizer application. The genetic diversity needed to improve nitrogen use efficiency of switchgrass remains underused, mainly because of the slow and laborious breeding process, thus leaving the crop's high nitrogen demand as a major barrier to ...
