I. introduction of varieties

1. Early ripening: the fruit fully matured in early August in Changli area, which was 7 days earlier than the main variety Victoria.

two。 Good taste and beautiful appearance: crisp flesh and strong rose flavor; variety fruit purplish red, fully ripe purplish black; excellent quality, soluble solids content up to 19.5%, up to 24.8%.

3. The fruit is early, high and stable: the ear is large, conical, the average ear weight is 720.6 g, the average grain weight is 9.5g, the maximum grain weight is 18.7g, and the fruit weight is 2.0g higher than that of the control variety pink Yadumi, which has the outstanding characteristics of early fruiting and early high yield. The average yield per mu of 2-year-old is 1650 kg.

II. Variety characteristics

The tip of the tender shoot is semi-open and the villi are coloring; the young leaves are wine-red, the adult leaves are green, 5-lobed. Mature branches smooth, reddish brown. Early ripening period, fruit ripening in early August; crisp flesh, rich rose flavor, purplish red, fully ripe purplish black; hard and crisp pulp, extremely sweet flavor, excellent quality, soluble solids content above 19.0%, titratable acid content of 0.49%, solid-acid ratio of 38.8; resistant to storage. Large panicle, average panicle weight 720.6g; fruit grain large, average kernel weight 9.5g; early fruiting, high yield and stable yield, average 1.35spike per fruiting branch; strong high yield, 3-5-year-old average 1806.7kg/667m2, Biadomi variety increased yield by 18.0%.

III. Key points of cultivation techniques

It can be propagated by cutting or grafting. Dulong stem shaping is suitable for small shed cultivation, plant spacing is 0.8m / 667m2, row spacing is 4.0m, planting is 167m / 667m2, hedgerow cultivation is suitable for single stem, single arm stem pruning, or "V" shape shaping, plant spacing is 0.6m / 0.8m, row spacing is 2.2 / 2.5m, and planting is 333 / 667m2. Pay attention to sprouting, wiping and peeling, so as to facilitate ventilation and light. The basal fertilizer 4000~5000kg/667m2 was applied when the seedlings were planted. Ear bagging is suitable for ear shaping and grain thinning at 25 days after anthesis, and bagging is suitable when the fruit grain is large as soybean.

Miguang grape is a kind of grape with relatively superior and high planting value. at present, the performance of the market is also very good. It also won the National Grape Gold Award in 2014, which is very suitable for planting.
