Abstract
Genetic progress has brought about a dramatic increase in yield potential per se for almost all production areas around the world. The present study examines the relationship of wheat yield with year of release, yield components, harvest index (HI), biomass production, and plant height. We used aggregative data from 1945 to 2010 to calculate genetic gain in wheat yield across different zones in China. A deeper understanding of these issues facilitates the identification of specific yield-limiting factors that can be used for future breeding strategies. Absolute yield gain for the different zones was found to range from 20 to 103 kg ha−1 year−1, whereas relative yield gain ranged from 0.33 to 1.42 % per year. When data from all the Chinese wheat production zones was pooled, yield gain at the national level had an absolute value of 66 kg ha−1 year−1 and a relative value of 1 % per year. Grain weight and spike weight, rather than the other yield components, are significantly correlated with year of release for most zones, suggesting that these two were the most promising traits for breeders in the past. These two traits are also responsible for the significant genetic progress in wheat yield in China since 1949. HI and biomass production also showed strong correlation with year of release and grain yield. In China, HI and grain weight have experienced such a substantial increase that both have almost reached their theoretical maxima in the period 1945–2010. Further improvement in the yield potential of wheat will have to involve increase in biomass production and grain number. This paper also reviews cropping systems and technologies as well as improvement in physiological trait from 1945 onwards during the period of genetic gain.

Abstract Selection based on single plants is a necessary step during early generations in breeding programs, where populations are still heterogeneous. A major problem is that individual plant performance is rather independent of crop performance, and there are few studies indicating physiological traits in individual plants that are reliable to select for to increase crop yield. In this context we aimed to find out whether it is possible to identify morpho-physiological traits in single spaced ...

Abstract Understanding agronomic and physiological performance of crop high yield is essential to make strategies for breeding and crop management. This study aimed to identify major agronomic and physiological traits associated with high grain yields of rice and wheat in the wheat–rice rotation system in the lower reaches of Yangtze River of China. Two high-yielding cultivars, each for winter wheat and rice, were field-grown from 2008 to 2010 for 3 years. Two crop management treatments, the loc...

Genetic progress for yield has been assessed globally in the semi-arid wheat yield trials (SAWYTs) of the International Maize and Wheat Improvement Center (CIMMYT) over a 17-yr period. Grain yield expressed as a percentage of the long-term check cultivar Dharwar Dry has increased at approximately 1% yr −1 between 1994 and 2010. In real terms, yield has been increased at a rate of 31 kg ha −1 yr −1 . The rate of yield increase in high-yielding environments was twice that of low-yielding environme...

Abstract Wheat is an important food crop worldwide. Genetic improvements have contributed much to wheat production since the 1960s. Verifying the evolution of agronomic traits and the physiological basis of grain yield will facilitate breeders and agronomists in developing new wheat cultivars, with the aim of stable and high yields. Thirty-five wheat cultivars, bred or widely planted in the Yangtze River Basin from 1950 to 2005, were grown in field experiments under three N rates (0, 112.5, and ...

Abstract New insights into changes in physiological processes associated with genetic gains in yield potential are essential for improved understanding of yield-limiting factors. Our field study was conducted at two sites with three N levels and 15 modern wheat ( Triticum aestivum L.) varieties. The goal was to evaluate yield components, time courses of dry matter production, and N accumulation among different yield categories, and to determine physiological processes associated with yield–trait...

Conservation agriculture involves reduced tillage, permanent soil cover and crop rotations to enhance soil fertility and to supply food from a dwindling land resource. Recently, conservation agriculture has been promoted in Southern Africa, mainly for maize-based farming systems. However, maize yields under rain-fed conditions are often variable. There is therefore a need to identify factors that influence crop yield under conservation agriculture and rain-fed conditions. Here, we studied maize ...

Abstract Understanding the key characteristics associated with genetic progress is essential to future wheat breeding strategies. Our objectives were to investigate the genetic progress in grain yield (GY) and key characteristics in wheat ( Triticum aestivum L.) cultivars released from 1964 to 2007 in Hebei province, China. Field experiments including 9 milestone cultivars were conducted during three growing seasons (2010–2011, 2011–2012, and 2012–2013) at Shijiazhuang of Hebei. Grain yield is s...

Molecular markers and phenotyping have been widely used to evaluate wheat germplasm diversity. However, the feasibility of using chromosome fluorescence in situ hybridization (FISH) to evaluate wheat genetic diversity has not been well investigated. In this study, seventy-six representative Chinese wheat lines in main wheat production area were selected and investigated with multicolour FISH using Oligo-pTa535, Oligo-pSc119.2 and Oligo-(GAA)8 probes. The results indicated that wheat chromosomes ...

Abstract Knowledge of allelic frequencies at loci associated with kernel weight and effects on kernel weight-related traits is crucial for yield improvement in wheat. Kernel weight-related traits were evaluated in 200 Chinese winter wheat cultivars (lines) grown at the Xinxiang Experimental Station, Chinese Academy of Agricultural Sciences , Xinxiang in Henan Province, for three consecutive years from 2014 to 2016. Alleles associated with kernel weight at nine loci, TaCKX6-D1 , TaCwi-A1 , TaCWI-...

Wheat yield components vary between different ecological regions and yield levels. Grain number responses to pre-anthesis dry matter (DM) and nitrogen (N) in increasing yield were always investigated in spike organs, neglecting the effect of non-spike organ nutrition or overall distribution. This paper determined the relationships between grain number and pre-anthesis DM and N in spike and non-spike organs under different yield levels, with using two sorts of field experiments (different water-n...

The final field trials to evaluate elite lines developed by the Embrapa national common bean breeding program generated a phenotypic database composed by agronomic traits of 84 elite lines and nine cultivars over a 16-year period (1993–2008) and 450 environments in all Brazilian growing areas. The main goal of this study was to use this database as a model to compare the consistency of the results obtained from indirect methods for genetic progress estimation for grain yield in common bean breed...

Genetic improvements have significantly contributed to wheat production. Five wheat cultivars—widely grown in north China in the 1950s, 1990s or 2010s—were grown in field experiments conducted in the 2014–2015 and 2015–2016 growing seasons. This study evaluated the genetic progress in wheat grain yield and its related traits in north China and explored how breeding and selection have influenced grain numbers and weights within spikelets in the past 60 years. The results showed that the significan...
