Choosing Crop Varieties For High Yield Performance

Selecting the optimal crop varieties is an integral step toward achieving high yield performance. When making this important decision, several considerations need to be considered such as maturity groupings, disease tolerance and standability of various varieties.

Evaluations must take place across several years and locations for accurate prediction of performances, so as to choose cultivars with consistent performances that will succeed in your fields.

Varieties with high yield potential

High-yield varieties (HYVs) have proven instrumental in increasing food production and helping alleviate hunger across many nations. While HYVs require specific conditions to reach their full potential, they produce more grain or other crop products than traditional strains. Furthermore, these genetically improved strains have played a pivotal role in increasing agricultural productivity during the Green Revolution; with shorter roots that resist lodging and being less sensitive to photoperiodicity meaning two or even three harvests annually can now be grown successfully with them.

As well as increasing yields, new varieties have also been created that can withstand both biotic and abiotic stresses, thanks to genetic modification and male-sterile varieties. CRISPR/Cas9 technology has recently been employed to generate heat sensitive male-sterile lines of rice, wheat and corn which breeders will use to develop hybrid hybrids with higher yield potential and better grain quality.

Selecting the optimal variety is key to increasing crop yields, with multiple factors impacting yield potential such as plant size, disease resistance and nutrient needs determining yield potential. Furthermore, selecting one adapted to your local climate and soil type – particularly winterhardy varieties which will continue producing even when weather becomes harsh.

Oklahoma State University Wheat Improvement Team’s Orange Blossom CL+ variety offers strong yield potential and excellent adaptability to local conditions, making it suitable for dual purpose purposes such as grazing while it grows to reduce feed costs for cattle producers. Due to its stem-like structure, planting depth can be greater and recovery after grazing can last longer than with most wheat varieties.

OSU Wheat Improvement Team recently conducted trials on CLL17 variety wheat in multiple locations, and discovered it outshone previous varieties in several categories including sheath blight resistance. Furthermore, blast and other diseases were less of a threat while it is susceptible to aphids requiring multiple applications of fungicide.

Varieties with disease tolerance

Disease tolerance in crops is an ideal characteristic, as it reduces chemical input costs and encourages eco-friendly farming practices. Disease tolerance becomes even more essential as climate change disrupts weather patterns that have previously been predictable and stressed crops. When choosing varieties with disease resistance, several factors need to be taken into account before selecting varieties with tolerance – first understanding under what conditions resistance works and secondly how this might impact on farm profitability.

Growing resistant varieties is often an expensive endeavor for growers, particularly if they must plant multiple fields to maximize yield potential. Due to climatic variations between fields and year-to-year yield variations, new varieties can be hard for farmers to accept; to reduce barriers associated with this practice, the CCARDESA Technical Brief 20 recommends farmers test resistance-tolerant varieties in their fields and collaborate with seed manufacturers in testing the performance of resistant varieties – including their ability to resist disease resistance, harvesting characteristics, palatability goals and any end use quality goals set forth.

Recent work undertaken at our institute utilized a model of plant disease epidemiology to investigate the impact of growing improved crops with either tolerant or resistant characteristics on disease dynamics. At low rates of horizontal transmission, an equilibrium with an all-control population (i.e. those using improved crops with tolerant traits) was reached when a certain proportion of growers used improved varieties with these characteristics resulting in high expected profits for users while low payoff for non-controllers, encouraging widespread participation in control.

At higher horizontal transmission rates, a bifurcation was observed, leading to different types of equilibrium depending on the cost of control (phC). Equilibria with phC = 0 were stable and unchanging as infection rate increased while those with phC 1 were less so but still did not collapse under similar infection pressures.

Growers should generally opt for resistant varieties rather than tolerant ones when selecting varieties for growing. This is due to tolerant crops not offering any advantages when infected, while resistant crops will offer significant gains when challenged with disease. Furthermore, tolerant crops are more likely to become infected and serve as carriers of infection – potentially increasing disease propagation further down the chain.

Varieties with good standability

When choosing soybean varieties, it’s essential to select those with excellent standability or lodging scores. This is especially essential if growing in sandy soils or fields receiving regular manure applications, or in wide rows requiring irrigation. A bushier variety may be more resistant to lodging than taller varieties due to their bushier growth habit and thin-line types’ ability to produce only a single stem whereas bushy varieties often produce multiple stems per plant while thin-line types might produce only a single straight one – the number of branches can vary accordingly; bushy varieties typically producing multiple stems while thin-line varieties can only produce one or two stems per plant while only producing thin-line types can produce only few stems per plant for each variety type.

Lodging can be a serious threat in soybean production areas and is responsible for significantly reduced yields. One effective solution to the lodging issue is planting varieties with superior standability – this means good emergence and seed size; additionally, those with a higher lodging score require lower seeding rates than their peers.

As part of your field evaluation process, it is also vitally important to take into account disease tolerance. While certain diseases such as soybean cyst nematodes and iron chlorosis may be managed with variety selection alone, others like sudden death syndrome and charcoal rot cannot. Therefore, selecting varieties resistant to such ailments is necessary in order to optimize yield potential and maximize your yield potential.

LGS4122E3 is an ideal variety for any environment that demands broad adaptation with superior emergence, as its roots can penetrate multiple soil types and tillage conditions, performing admirably in our trials. Additionally, its superior stress tolerance makes it perfect for environments with wet periods. Plus it boasts excellent yield potential thanks to resistance against SCN, PRR, IDC white mold and brown stem rot and high ratings of Phytophthora root rot resistance and soybean blast resistance! Furthermore it makes an excellent double crop planting soybean with high herbicide tolerance traits; making it the perfect candidate for growers looking to maximize yield potential on Enlist platforms.

Varieties with good grain dry-down

Drying down crops effectively is essential to harvesting with profitable moisture levels, with temperature, weather conditions and variety selection all playing roles in its success. Early maturing varieties typically dry down faster due to having more favorable drying conditions early in the growing season than later maturing varieties – this reduces desiccant use which could otherwise negatively impact grain quality as well as become costly for farmers.

Crop genetics continue to advance thanks to breeders’ efforts at improving yield potential while simultaneously increasing disease tolerance, nutritional qualities and climate resilience. By rotating hardy varieties into their crop rotation plans, producers can protect their fields while building more sustainable and adaptable systems over time.

Numerous factors contribute to the drying down rate of durum varieties, including daily growing degree days (GDD) accumulation and the size of their husks. A larger husk reduces how much heat and light are absorbed by grain, hastening dry down. Furthermore, their number, thickness, tightness, etc. all play an integral part.

Durum varieties that produce high yields must also withstand fluctuations in soil nutrient content, something which can be especially challenging in regions with variable rainfall patterns and short growing seasons. To accomplish this goal, they must be capable of taking in enough nutrients without overabsorbing them; thankfully newer durum varieties have been created with enhanced drought and frost resistance properties.

Stellar durum wheat variety was developed through backcrossing low linolenic acid mutants with variety Regent to produce low levels of linolenic acid while still yielding high yields, providing farmers with excellent weed control capabilities and resilience against drought and frost conditions. As such, it makes an excellent option for areas experiencing unpredictable climate conditions.
