CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Japanese Variety Registration Application No. 32562 filed Nov. 1, 2017, which is incorporated by reference herein as if set forth in its entirety.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of apple tree botanically classified as Malus Mill. and hereinafter referred to by the name ‘TAKANO 7GO’.

The new variety is a product of a planned breeding program conducted during a period from May 2006 to September 2017 by the inventor, Oshu-shi, Iwate, Japan, in which the Malus Mill. variety ‘Shinano Gold’ (female parent; Japanese Variety Registration No. 7328, registered Aug. 11, 1999) was crossed with the Malus Mill. variety ‘TAKANO 1GO’ (male parent) which is also known as the name ‘Beni Roman’ (Japanese Registered Trademark No. 5128504, registered Apr. 11, 2008) in Japan. The objective of the breeding program was to create new apple trees that produce fruits having long common storage duration and firm flesh, different from those of the parents and known similar varieties.

SUMMARY OF THE INVENTION

The new and distinct variety ‘TAKANO 7GO’ has a longer common storage duration of about one month even at an average temperature of about 20-25° C., balanced sweetness (about 14.5-15 (Brix %)) and acidity (about 0.33 g/100 ml) of the fruit, higher firmness of the flesh (about 15.3 lbs.), and earlier harvest time (for example, late August to early September in Japan), and, as described below, is distinct from: the known variety ‘Shinano Gold’ (female parent) that was produced by crossing the Malus Mill variety ‘Golden Delicious’ which is a classic American apple variety and is also well known in Japan with the known variety ‘Senshu’ (Japanese Variety Registration No. 42, registered Mar. 31, 1980), the known Malus Mill. variety ‘TAKANO 1GO’ (male parent, Japanese Variety Registration No. 20599, registered Mar. 15, 2011) that was produced by crossing the known Malus Mill variety ‘Shinano Red’ (Japanese Variety Registration No. 5867, registered Dec. 5, 1997) with the known Malus Mill. variety ‘Sansa’ (Japanese Variety Registration No. 1565, registered Mar. 5, 1988); and the Malus Mill. variety ‘Tsugaru’ well known in Japan.

 DETAILED BOTANICAL DESCRIPTION

The new variety ‘TAKANO 7GO’ has characteristics as described below, compared with the parent varieties and similar varieties. (see TABLEs 1, 2 and 3).

TABLE 1 Partial characteristics of ‘TAKANO 7GO’ Characteristic State Tree: type ramified Tree: habit spreading Fruit: height medium, about 8 cm on average Fruit: general shape ovoid Fruit: relative area of overcolor very large Fruit: hue of overcolor, with bloom orange red (RHS, removed approximately N34A) Fruit: intensity of stripes of overcolor weak Fruit: color of flesh yellow white (RHS, approximately 158D) Time of beginning of flowering medium Time of harvest early

The variety ‘Shinano Gold’, a female parent, has the characteristics of that the skin color is yellow (RHS Yellow Group approximately 6C) when harvested, the sweetness of flesh is high (about 15.3 (Brix %)), the acidity of flesh is medium (about 0.45.g/100 ml), the firmness or food texture (i.e., mouthfeel) of flesh is firm (about 15.5 lbs.), and the time of harvest is late, specifically late October in Iwate, Japan.

The variety ‘TAKANO 1GO’, a male parent, has the characteristics that the skin color is red (RHS Red Group approximately 46B) when harvested, the color of flesh is yellow white (RHS Yellow-White Group approximately 158D), the acidity of flesh is about 0.50 g/100 ml, the firmness of flesh is about 16.0 lbs., the time of harvest is very early, specifically mid of August at Iwate, Japan, and the common storage duration is short (about 4-10 days in August at Iwate, Japan).

On the other hand, the new and distinct variety ‘TAKANO 7GO’ has the characteristics described in TABLE 1 above and TABLEs 2 and 3 below, especially that the time of harvest is from late August to early September at Iwate, Japan and the common storage duration is long (about one month even in the period late August to early September at Iwate, Japan (average temperature about 20-25° C.)) substantially without making the flesh soft and thus very superior to any known variety produced in Japan (normally up to about 10 days), that the skin color of the fruit is orange red (RHS Orange-Red Group approximately N34A) when harvested, and the color of the flesh is yellow white (RHS Yellow-White Group approximately 158D) and the firmness of the flesh is firm (about 15.3 lbs.), and that the sweetness of the fruit is about 14.5-15 (Brix %) and is higher than the sweetness of known fruits like ‘Beni Roman’ (i.e. the variety ‘TAKANO 1GO’) (about 13 (Brix %) and ‘Sansa’ (about 13-14 (Brix %)), and the acidity of the flesh is medium (about 0.33 g/100 ml), while having balanced sweetness and acidity and higher firmness of the flesh. Furthermore, in the new and distinct variety ‘TAKANO 7GO’, the leaves are arranged alternatively on the stem with one leaf per node in a straight line.

TABLE 2 Comparison of characteristics between the new variety and similar varieties Varieties Sansa (not Tsugaru (not Characteristic TAKANO 7GO patented)*1 patented)*1) Stripes of overcolor weak absent — Duration of common long, slightly short, slightly short, storage about 1 month 10 days or less 10 days or (at about 20-25° C.) less Fruit firmness of firm, slightly firm, soft, flesh about 15.3-16.0 about 13.8 lbs about 13.0 lbs lbs. *1)‘Sansa’ and ‘Tsugaru’ are similar to ‘TAKANO 7GO’ in their harvest time.
