Introduction to the Miguang Grape Variety and a Detailed Explanation of Its Main Characteristics

Grapes are a fruit that people in both the north and the south enjoy eating, and the Miguang grape is a widely cultivated grape. Together with Chunguang and Baoguang, it is known as the “Three Lights”. Let's take a look below at the introduction to the Miguang grape variety.

1. Variety Introduction

1. Early ripening: In the Changli area, the fruit reaches full maturity in early August, ripening 7 days earlier than the main commercial variety Victoria.

2. Good taste and beautiful appearance: The flesh is crisp and has a rich rose aroma; the fruit is purplish-red, turning purplish-black when fully ripe; the quality is excellent, with soluble solids content reaching more than 19.5%, and up to 24.8% at the highest.

3. Early fruiting, high and stable yield: The clusters are large and conical, with an average cluster weight of 720.6 grams; the berries are large and oval, with an average berry weight of 9.5 grams and a maximum berry weight of 18.7 grams, the berry weight exceeding that of the control variety Pink Yadumi by 2.0 grams; it has the outstanding excellent characteristics of early fruiting and early high yield. The average yield of 2-year-old vines reaches 1650 kg per mu.

2. Variety Characteristics

The shoot tip of the young shoot is half-open, with medium-colored down; the young leaves are wine-red, and the mature leaves are green with 5 lobes. The mature canes are smooth and reddish-brown. The ripening period is early, with the fruit ripening in early August; the flesh is crisp and has a rich rose aroma, purplish-red, turning purplish-black when fully ripe; the flesh is firm and crisp, extremely sweet in flavor, with excellent quality, soluble solids content above 19.0%, titratable acid content of 0.49%, and a solid-acid ratio of 38.8; it is resistant to storage and transport. The clusters are large and the berries are large, with an average cluster weight of 720.6 g; the berries are large, with an average berry weight of 9.5 g; it fruits early, with high and stable yield, averaging 1.35 clusters per fruiting cane; it has strong yielding ability, with 3- to 5-year-old vines averaging 1806.7 kg/667 sq m, an increase of 18.0% over the Yadumi variety.

3. Key Points of Cultivation Techniques

Propagation can be done by either cuttings or grafting. For small trellis cultivation, use single-dragon-trunk training, with a plant spacing of 0.8-1 m and a row spacing of 4.0 m, planting 167-208 plants/667 sq m as appropriate; for hedge trellis cultivation, single-trunk single-arm dragon-trunk pruning or “V”-shaped training can be used; with a plant spacing of 0.6-0.8 m and a row spacing of 2.2-2.5 m, planting 333-378 plants/667 sq m as appropriate. Pay attention to bud thinning, shoot tipping, and pinching of secondary shoots to facilitate ventilation and light penetration. When planting the seedlings, apply base fertilizer at 4000-5000 kg/667 sq m. For bagging the fruit clusters, shape the clusters and thin the berries 25 d after flowering, and bagging is appropriate when the berries are the size of soybeans.

The Miguang grape is a relatively superior grape with relatively high cultivation value. Its current market performance is also very good, and in 2014 it also won the gold award in the national grape competition, making it very suitable for cultivation.
