“…This may include crop rotation and tillage systems which improve fallow moisture or nutrition. If weeds or Lepidopterous insects are a major constraint for yield, then GM herbicide resistance traits or Bt traits have helped to improve yield (Campbell et al, 2014). Likewise, where disease is a constraint, resistant cultivars are important (Liu et al, 2013;Stiller and Wilson, 2014).…”

“…In an assessment of genetic improvement in US cotton, Campbell et al (2014) concluded that GM trait adoption paralleled yield improvements and genetic gains from long-term breeding efforts. Thus, the package of improved crop management and conventional breeding with GM traits has increased the yield potential of US cotton and it is possible that overcoming difficult weed and insect management problems can allow management to focus on other important issues, such as nutrition and irrigation.…”

“…2), although many countries still have average yields less than 1000 kg lint/ha. Those countries with higher yield have been increasing at rates between 10 and 30 kg lint/ha/year (Campbell et al, 2014 for US; Fig. 2 for Australia, Brazil and Turkey) but there are a number of countries and regions such as Uzbekistan and French West Africa where yields have stagnated in their production systems, likely due to combinations of water availability, soil constraints and crop nutrition.…”

Enhanced utilization of defatted cottonseed meal (CSM)-based products as biobased raw materials would increase the profitability of cotton growers and processors. In this work, a multiple-step procedure that can be used to produce water washed cottonseed meal (WCSM) and a co-product water soluble cottonseed protein (CSPw) from CSM was tested at pilot scale. Alternatively, the procedure can also be used to produce CSPw, alkali soluble protein (CSPa) and the protein extracted insoluble residue (CSIR). The chemical composition of these pilot-produced products was generally comparable to that of the corresponding laboratory-prepared products. The fiber content was higher in the pilot-produced WCSM than in laboratory-produced product mainly due to the higher fiber content in the mill-based starting meal material used in the pilot trial. The protein content in the pilot-produced CSPw was only 64.4% of the solid matter, indicating that additional rinse is needed before drying the HCl-precipitated CSPw fraction. Per the yield and composition data, it was concluded that it was feasible to produce the four products WCSM, CSPw, CSPa, and CSIR from CSM in a large scale. Thus, adoption of this procedure would provide the necessary quantities for exploring the practical utilization of these products in biomaterial industry.

“…Plant breeders need to assess the relative rates of gain to understand priorities of a program. Genetic yield gain estimates in cotton suggest that yields have improved by 0.0216 t ha −1 annually from 1981-to 2011 (Campbell et al, 2014). These era studies evaluate genotypes from different eras under equal environment and management conditions are useful to establish the relative value of plant breeding effort in yield gains (Duvick, 1984(Duvick, , 2005a(Duvick, , 2005bSmith et al, 2004) Duvick et al (2004) estimated the rate of genetic yield gains to be 0.077 t ha −1 yr −1 in DuPont Pioneer's corn breeding program.…”

Long‐Term Selection in Hybrid Sorghum Breeding Programs

et al. 2019

Estimating genetic gains in sorghum [Sorghum bicolor (L.) Moench] is necessary to assess whether the current rates of improvement will meet future production demands. The current study was conducted to determine the rate of genetic gain in yield and associated traits over the commercial hybrid era using sorghum germplasm from the Texas A&M sorghum breeding program and a US sorghum seed company. From the Texas A&M AgriLife program, 60 hybrids that represented a 50‐yr span of hybrid breeding were grown and evaluated in five environments across Texas in 2016. In a separate set of trials, 14 commercial hybrids representing a similar timespan were evaluated in three Texas environments in 2016. In both programs, grain sorghum yields increased 0.008 t ha−1 annually over their respective timespans. Traits that increased over time included yield potential per plant, heterosis, test weight, panicle size, and grain number per panicle, whereas leaf angle, days to maturity, plant height, and yield stability demonstrated little to no change. Overall, ∼60% of total yield gains in US sorghum production are attributed to genetic improvement through sorghum breeding. Compared with other major US field crops, the rate of genetic gain in sorghum has been slower, presumably due to a combination of factors, which include continually shifting production environments, changing priorities in traits, reduced research investments (compared with other crops), and less‐than‐optimized heterotic groups.
