Rice production needs to increase in the future order meet increasing demands. The development of new improved and higher yielding varieties more quickly will be needed this demand. However, most rice breeding programmes world have not changed several decades. In article, we revisit evidence favour using rapid generation advance (RGA) as a routine method. We describe preliminary activities at International Research Institute (IRRI) re-establish RGA on large scale main method for irrigated...
Despite strong interest over many years, the usage of quantitative trait loci in plant breeding has often failed to live up expectations. A key weak point utilisation QTLs is "quality" markers used during marker-assisted selection (MAS): unreliable result variable outcomes, leading a perception that MAS products fail achieve reliable improvement. Most reports for focus on derived from mapping population. There are very few studies examine reliability these other genetic backgrounds, and...
While a multitude of genotyping platforms have been developed for rice, the majority them not optimized breeding where cost, turnaround time, throughput and ease use, relative to density informativeness are critical parameters their utility. With that in mind we report development 1K-Rice Custom Amplicon, or 1k-RiCA, robust custom sequencing-based amplicon panel ~ 1000-SNPs uniformly distributed across rice genome, designed be highly informative within indica pools, tailored genomic...
Abstract Rice genetic improvement is a key component of achieving and maintaining food security in Asia Africa the face growing populations climate change. In this effort, International Research Institute (IRRI) continues to play critical role creating disseminating rice varieties with higher productivity. Due increasing demand for rice, especially Africa, there strong need accelerate rate grain yield. an effort identify characterize elite breeding pool IRRI’s irrigated program, we analyzed...
In the last decade, association mapping (AM) has become a well-established method to detect genes and quantitative trait loci (QTLs) associated with agronomically important traits. The identification of large number single nucleotide polymorphisms (SNPs) from genome sequencing concurrent development high-throughput genotyping platforms led AM being widely used for range crops. These technologies have been in rice (Oryza sativa) explore abundant diversity there is enormous potential identify...
Rice breeding of inbred varieties in the public sector has hardly changed decades. This been a cause for concern given that current rate yield improvement from new is not considered to be adequate meet future global demands rice. In this article, we describe major changes irrigated program and former plant division at International Research Institute (IRRI) headquarters by incorporating modern concepts practices used private sector. These activities were conducted primarily within five-year...
Abstract Background Assessing the performance of elite lines in target environments is essential for breeding programs to select most relevant genotypes. One main complexities this task resides accounting genotype by environment interactions. Genomic prediction models that integrate information from multi-environment trials and environmental covariates can be efficient tools context. The objective study was assess predictive ability different genomic optimize use information. We used 111...
Climate change will continue to have a largely detrimental impact on the agricultural sector worldwide because of predicted rising temperatures, variable rainfall, and an increase in extreme weather events. Reduced crop yields lead higher food prices increased hardship for low income populations, especially urban areas. Action climate is one Sustainable Development Goals (SDG 13) linked Paris Agreement. The research challenge posed by so complex that trans-disciplinary response required,...
The pedigree, bulk, and single-seed descent-based rapid generation advance methods are commonly practiced breeding in rice. But the efficiency of these enhancing genetic gain has not been investigated yet. In this study, we compared pedigree bulk method-derived lines five crosses with RGA-derived lines. RGA method was found to be almost two times more efficient capturing high-yielding a high value thus accelerated much than methods. is only but also significantly cheaper (~24%) cost per...
Integrated breeding approaches such as combining marker-assisted selection and rapid line fixation through single-seed-descent, can effectively increase the frequency of desirable alleles in a program rate genetic gain for quantitative traits by shortening cycle. However, with most genotyping being outsourced to 3rd party service providers' nowadays, sampling has become bottleneck many programs. While seed-chipping prevailed an automatable seed protocol species, symmetry rice seeds makes...
Association analysis for ionomic concentrations of 20 elements identified independent genetic factors underlying the root and shoot ionomes rice, providing a platform selecting dissecting causal variants. Understanding basis mineral nutrient acquisition is key to fully describing how terrestrial organisms interact with non-living environment. Rice (Oryza sativa L.) serves both as model organism studies an important component global food system. Studies in rice ionomics have primarily focused...
