Tomato potted plants
First, cherry tomatoes
The ancestor of tomato is L.esculentumVar.cerasiforme, which is the only wild tomato found outside South America. Cherry tomato is more adaptable to tropical and humid environment than other common tomato varieties. There is a close relationship between current tomato varieties and wild cherry tomatoes. These two types easily cross each other.
The plant grows sturdily, its stem is tendril-shaped, and its surface is covered with thin and short yellow hairs (2.5 mm long). The leaves are big. The notch is deep, the lobes are long, the apex is gradually pointed, and the middle lobe is oval, oval or round. Inflorescence is mainly solitary, long or short, with few flowers, mainly composed of 5 perianth, and a few have 6 perianth. The calyx is almost as long as the petals. Ovary spherical, stigma short or as long as stamens. The fruit is spherical and fiery red. Dark yellow, 2 locules, smooth or hairy fruit and heart-shaped seeds. It's fluffy.
This variety has a wide distribution area: in Mexico and Central America. Distributed in Peru and other places. Cherry tomato fruit tastes sour, which is widely used in canned food and can also be used as the original material for breeding disease-resistant varieties.
Second, pear-shaped tomatoes.
The plant grows moderately, the stems are erect or prostrate, smooth or hairy, and the leaves are medium to large. Inflorescences are mainly single inflorescences and racemes. A few branches are stout, with few flowers and occasionally many. Calyx is shorter than petals. The petals gradually taper into an oval shape. Ovary long, stigma short or equal to stamens, fruit 2-loculed, occasionally 3-loculed. Fruit shape index 1.5 ~ 2.0, and the fruit color is red and yellow. Pink, heart-shaped and fluffy.
The offspring obtained by crossing pear-shaped tomato with spherical tomato are oval, oblong and oval; The offspring obtained by crossing with cultivated varieties have great variation, which provides great selectivity and can obtain many valuable varieties.
Three, plum tomato (variety pruniforme)
The plant grows moderately, with stem height 130 ~ 150 cm, medium-sized leaves, deeply notched lobes and a single inflorescence. Short, 8 ~10cm long. Flowers are few, about 7, of medium size, with 5-6 petals, 2cm in diameter, and the style length is equal to that of stamens. The fruit is small (2.5 ~ 3.0 cm long and 1.5 ~ 2.0 cm wide), with fruit shape index 1.5 ~ 2 and 2 compartments. Single fruit weight 15 ~ 20g, with red, yellow and pink fruit color and few seeds.
Four. Tomato (long spike variety)
The plant grows moderately strong, with erect or creeping stems, 70 cm high, covered with villi, medium to large leaves, elliptic and entire lobes. Inflorescence has a single raceme, occasionally a complex raceme, with many flowers, usually 7, 5 perianth and a few 6. Sepals are shorter or longer than petals, and styles are equal to or longer than stamens. The fruit weighs 30 ~ 50g, and it is red, pink and dark yellow.
This species is edible, widely distributed and has a high dry matter content. Therefore, it is a good raw material for cultivating processed varieties. At the same time, it has low requirements for soil and strong adaptability.
Five, ordinary tomatoes
The plants grow vigorously, and the stems are tendril-like, semi-tendril-like or dwarf. The branches are weak and strong, with fluff on the body surface, large and large leaves, and no plastic nicks. The color of the leaves varies from light green to dark green, and the edges of the leaves have blunt serrations to sharp serrations. Inflorescences have racemes or compound racemes, and flowers range from a few to many. Fruits have varieties of various shapes, colors, sizes and maturity, and most cultivated varieties are concentrated in this variety.
Six, big leaf tomato
Plant growth is moderate and robust, and leaf coverage is moderate or sparse. The stem is creeping. The quilt has fluff, big leaves and leaves like potatoes. So it is also called potato leaf tomato. The lobes of leaves are 1 ~ 2 pairs, which are whole. Interlobular and interlobular loss. Inflorescences are simple or complex. Flowers are small, with 5-7 perianth. Fruits are round, oblate and oblate, and some are oval. There are several to many sub-venues. The fruit is fiery red in color. Pink or yellow, etc.
This variety is rare among cultivated varieties and has no special economic cultivation value. It is classified as a variety only according to the particularity of leaf shape.
Seven, upright tomato (Var.valiudmBaily)
The plant is stout, short or medium in height, strongly branched, with thick and erect stems, short internodes and fluff on the stems. Petiole is short, leaves are dark green and wrinkles are obvious. Inflorescence from simple to complex, flowers from few to many, flowers from small to large, with 5 ~ 6 perianth. The fruit is spherical, oblate or oblate with a smooth or diamond surface. There are two main kinds of fruits: lux and pink.
Eight, thin leaf tomato (Lycopersicon pellifolium (JUS1) mill)
Colored fruit of wild species of tomato. It is easy to see in Peru at low altitude. Its wild species grow in coastal valleys all over Peru, and fine-leaved tomatoes can be collected along the northern coast of Peru (7 ~ 8 south latitude). Tomatoes with good leaves can also be collected around the Lima River and at the southernmost tip of Peru near the Chilean border.
Small leaf tomato and common tomato can be crossed, and the genetic relationship is very close. This is the only wild species that shows natural infiltration with common tomato. In both cases, lobular tomato plays an important role in the evolution of cultivated tomato, because the current varieties are closely related to it and easy to backcross. Tomato with exquisite leaves is an attractive germplasm resource in plant breeding. Taking tomato with good leaves as parents, varieties resistant to Fusarium wilt and bacterial spot disease were bred.
Finally, Bian Xiao needs to remind friends that all common tomato varieties are self-fertile, and they are the only varieties that can self-pollinate, and the fruits of common tomatoes have various shapes, so we must not only observe the fruit shape when distinguishing.
