How Variety Selection Shapes Growth, Yield and Nutrition in Western Malwa Plateau
Imagine biting into a plump, red strawberry—its sweet yet slightly tart juice bursting in your mouth. This simple pleasure, enjoyed worldwide, belies a complex agricultural challenge: growing the perfect strawberry isn't easy, especially in specific regional conditions like Western Malwa Plateau.
Strawberries are not true berries botanically. They are aggregate fruits because they form from multiple ovaries of a single flower.
As climate change alters growing conditions and consumer demands evolve, agricultural researchers are racing to identify which strawberry varieties will thrive in particular regions while delivering the optimal yield, size, and nutritional content that both farmers and consumers desire.
The significance of this quest extends far beyond the fruit bowl. Strawberries represent an important cash crop for small and marginal farmers in many regions, including India, where their cultivation has expanded into non-traditional areas. Understanding how different cultivars respond to local conditions isn't merely academic—it directly impacts farm viability, local economies, and food security.
Choosing the right variety can make or break a farming season
Strawberries provide important income for regional farmers
Optimized crops contribute to stable food supplies
At the heart of productive strawberry cultivation lies a simple truth: not all strawberries are created equal, especially when grown outside their ideal conditions. The genetic makeup of each cultivar determines everything from its chilling requirements (the cold period needed to trigger fruiting) to its disease resistance, fruit size, and nutritional profile.
Research has demonstrated that different cultivars exhibit remarkable variation in key growth parameters. For instance, studies under protected cultivation conditions have shown that cultivar 'Nabila' achieved maximum plant height (25.80 cm) and produced the most runners (5.76 per plant), while 'Sabrina' exhibited the earliest flowering and fruiting 1 .
The table below illustrates how strawberry cultivars can vary across key growth parameters:
| Cultivar | Plant Height (cm) | Days to First Flowering | Number of Runners | Days to Fruit Maturity |
|---|---|---|---|---|
| Nabila | 25.80 | ~55 | 5.76 | ~75 |
| Sabrina | ~23 | 51.43 | ~4 | 69.39 |
| Gili | ~20 | ~56 | 2.68 | ~77 |
| E1-1333 | ~22 | 56.93 | ~3 | 78.13 |
To understand how different strawberry varieties perform under the specific conditions of Western Malwa Plateau, researchers designed a comprehensive comparative study. The experiment investigated multiple strawberry cultivars—including popular choices like 'Sabrina', 'Nabila', and 'Gili'—evaluating their performance across growth parameters, flowering patterns, fruiting characteristics, and fruit maturity timelines 1 .
The research was conducted using a Randomized Complete Block Design (RCBD), a standard agricultural research approach that minimizes the effect of variability in the field.
The plants were grown under protected conditions (net tunnels), which help moderate extreme weather events and protect delicate flowers and fruits.
The results revealed striking differences between the strawberry cultivars tested, highlighting the importance of selecting the right variety for specific growing conditions and market needs.
Recorded the maximum plant height (25.80 cm at 120 days after planting) and the highest number of runners per plant (5.76) 1 .
Proved to be the earliest maturing variety, requiring the fewest days to first flowering (51.43 days) and reaching fruit maturity in just 69.39 days 1 .
| Parameter | Nabila | Sabrina | Gili | E1-1333 |
|---|---|---|---|---|
| Plant Height (cm) | 25.80 | ~23 | ~20 | ~22 |
| Plant Spread - E/W (cm) | 32.50 | ~29 | 27.40 | ~28 |
| Number of Runners | 5.76 | ~4 | 2.68 | ~3 |
| Days to First Flowering | ~55 | 51.43 | ~56 | 56.93 |
| Days to Fruit Maturity | ~75 | 69.39 | ~77 | 78.13 |
While growth parameters and yield are crucial for farmers, fruit quality and biochemical composition increasingly influence consumer preferences and market success. Contemporary strawberry research has expanded to include detailed analysis of nutritional content and bioactive compounds that contribute to both flavor and health benefits.
Different strawberry cultivars show remarkable variation in their biochemical profiles. Research on new advanced breeding selections has revealed that cultivars like 'Dina', 'AN15,07,53', and 'AN16,53,54' contain higher levels of soluble sugars, organic acids, and anthocyanins compared to other varieties 2 .
These compounds directly influence fruit quality—sugars and acids determine the signature sweet-tart balance of strawberries, while anthocyanins contribute both to the vibrant red color and the antioxidant properties that make strawberries a valued functional food.
| Cultivar/Breeding Line | Soluble Sugars | Organic Acids | Anthocyanins | Special Characteristics |
|---|---|---|---|---|
| Dina | High | High | High | Excellent balance of quality parameters |
| AN15,07,53 | High | High | High | Derived from parents with varying chilling requirements |
| AN16,53,54 | High | High | High | Anticipated peak production, suitable for organic systems |
| Elide | Medium | Medium | Medium | Highest total yield (632 g plant⁻¹) |
| Fortified Strawberry Powder | - | - | - | Provides 20% and 58% of daily FA and Zn for pregnant women 3 |
The pursuit of nutritional enhancement has led to innovative approaches like fortification. Recent research has successfully developed strawberry powder fortified with zinc and folic acid, containing 272.3 mg/100g folic acid and 0.21% zinc—sufficient to provide 20% and 58% of daily reference values for pregnant women, respectively 3 .
This innovation demonstrates how strawberries can be transformed into value-added products addressing specific nutritional deficiencies, particularly important for maternal and child health in regions with nutritional challenges.
The implications of varietal selection extend beyond immediate harvest metrics to broader agricultural sustainability. Research has shown that appropriate biostimulants can further enhance strawberry performance, particularly in organic production systems.
Application of plant-derived protein hydrolysate increased fruit yield per unit area by 13.5% and enhanced photosynthetic performance in organically grown strawberries 4 .
Integration of sensors to monitor microclimate conditions allows growers to optimize conditions for specific varieties 2 .
Identifying varieties with adaptability to warmer conditions becomes increasingly crucial as climate patterns shift 2 .
Breeding programs are now focusing on developing cultivars with lower chilling requirements that can maintain productivity in warming temperate zones 2 . The Western Malwa Plateau conditions, with their specific climatic challenges, serve as an important testing ground for varieties that might thrive in future climate scenarios.
Strawberry research relies on specialized materials and methodological approaches to obtain reliable, reproducible results. The following table outlines key components used in evaluating strawberry varieties:
| Item Category | Specific Examples | Function in Research |

The journey to identify ideal strawberry varieties for specific regions like Western Malwa Plateau represents far more than academic curiosity—it's a vital pursuit with real-world implications for farmers, consumers, and the environment. Through meticulous comparative studies, researchers have revealed that strawberry cultivars differ dramatically in their growth patterns, reproductive behaviors, and fruit qualities, with no single variety excelling in all parameters.
The future of strawberry cultivation lies in matching the right variety to specific local conditions, market needs, and farming systems. As research continues to uncover the complex interactions between genetics, environment, and management practices, growers will be increasingly equipped with the knowledge needed to optimize both productivity and sustainability. The humble strawberry thus serves as a model for how agricultural science can help adapt our food systems to changing conditions while enhancing both the quantity and quality of the crops we depend on and enjoy.
