All India Coordinated Vegetable Improvement Project (AICVIP) was started in 1970 - 71 and under this, India is divided into 8 operational zones. The headquarter of the project was at the Division of vegetable Science, ICAR, New Delhi.
It aims to provide a national network for multi-location testing of vegetable technologies developed by various research institutes and state agricultural universities.

The first variety of Hybrid Teas (H. T.) class of rose is La France developed in France in the year 1867.
It was originally developed by crossing between hybrid perpetuals and Tea roses. It is the most popular rose bearing large highly centered flowers.
Hybrid teas are the largest and most popular group of roses, due to their elegant form and a large variety of colours. Their flowers are usually borne singly at the end of the long stems which makes them very popular as cut flowers.

The most serious disease of the vegetable seedling is Damping off.
It is a soil-borne fungal disease caused by Rhizoctonia, Fusarium or phytophthora, etc. It negatively affects the vegetables and flowers in your garden, primarily targeting seeds and new seedlings.
Damping-off refers to the rotting of stem and root tissues at and below the soil line. In most cases, infected plants will germinate and come up fine, but within a few days, they become water-soaked, mushy, collapse at the base and die.

Granulation can be reduced by the spraying of Lead arsenate in dilution of 200 - 500 ppm.
Granulation is drying up, becoming hard with greyish colour and enlargement of the juice vesicles with an increase in pectin, lignin, etc. resulting in a reduction of the juice content.
It is a common physiological disorder of postharvest citrus fruit. It results in the rapid deterioration of sugars and organic acids of fruit, disordered juice sacs become hard and even lose their edible value. Thus, granulation was emerging as a heavy threat to the citrus industry development.

Tip-top variety is related to Tomato.
Tip Top is shaped like a spinning top. They are medium-sized plum-shaped tomatoes and are pretty much determined with limited production after the main flush of fruit. It takes 70 - 80 days to mature.
The fruits are tasty and not dry. The walls are pulpy and great for salads, salsas and canning.

Citrus exanthema is caused by a deficiency of Copper. The disease is usually attributed to malnutrition and is not infectious.
The dropping, blemishing, and cracking of fruit form one of the most common symptoms of exanthema disease in fruit. Brown glossy areas occur particularly on side of the fruit. The surface shows small dots of gum. Cracking is common. The fruit is undersized and often a pale yellow.
It can be treated with a copper treatment.

Asafoetida is harvested by Tapping.
The hing is in the form of dried latex gum, which is discharged from the herb called Rhizome or ferula of several tap roots, the herb named perennial herb grows at a height of 1 to 1.5 in length.
The gum resin is obtained from incisions in the roots and rhizomes of the plants. The roots of the plants are exposed to the surface by cutting the plants very close to the roots which then secrets a milky juice from the cut area. The substance hardens when exposed to air and is extracted by the tapping method.

Meristem is the portion of the plant that is considered to be free from viruses. The apical and axillary meristems of plants are the best parts to make virus-free plants because of their high rate of multiplication and division which means the growth of meristems are much faster than the viral multiplication and virus are unable to invade the newly formed cells.

An example of a Biennial vegetable is Carrot.
Biennials are such plants that require two years to complete their life cycle. First-year growth results in a small rosette of leaves near the soil surface. During the second year of growth stem elongation, flowering, and seed formation occur followed by the entire plant's death.
In carrots, swollen roots are produced in the year of sowing and are harvested, stored and consumed. To produce seeds, the roots must be left and after vernalizing, the plants that flower in the following year. The plant produces a tall stem with many branches bearing seeds.
