Correct Answer
Solanum melongena
Explanation
Solanum melongena L. is the scientific name for Brinjal, also known as eggplant. It belongs to the Solanaceae family.
Correct Answer
Solanaceae
Explanation
Brinjal is a member of the Solanaceae family, which also includes tomato, potato, and chilli. This family is known for its diverse range of food and medicinal plants.
Correct Answer
India
Explanation
India is considered the primary center of origin for Brinjal (Solanum melongena). It has been cultivated in the region for thousands of years.
Correct Answer
Berry
Explanation
Botanically, the fruit of the Brinjal plant is classified as a berry. Berries typically develop from a single ovary and contain multiple seeds.
Correct Answer
Day Neutral Plant
Explanation
Brinjal is a day-neutral plant (DNP), meaning its flowering is not significantly affected by the length of day or night. This allows it to be grown across different seasons.
Correct Answer
Pentamerous
Explanation
The flowers of the Brinjal plant are described as pentamerous. This means their floral parts (like petals and sepals) are typically arranged in multiples of five.
Correct Answer
Eggplant
Explanation
Eggplant is a common name for Brinjal, particularly in North America and Australia. The name 'Aubergine' is more common in British English.
Correct Answer
6.5 - 7.5
Explanation
Brinjal thrives best in soils with a pH range of 6.5 to 7.5. This slightly acidic to neutral pH ensures optimal nutrient availability for the plant.
Correct Answer
13-21°C
Explanation
The NCERT guidelines suggest an average temperature range of 13-21°C for successful Brinjal cultivation. However, optimal growth occurs between 20-30°C.
Correct Answer
Anthocyanin
Explanation
Anthocyanin pigments are responsible for the characteristic purple color of many Brinjal varieties. These pigments are water-soluble flavonoids.
Correct Answer
Solasodine/Glycoalkaloid
Explanation
Solasodine, a type of glycoalkaloid, is the primary compound responsible for the bitterness sometimes found in Brinjal. Levels vary between varieties and maturity stages.
Correct Answer
400-500 gm
Explanation
For standard, open-pollinated Brinjal varieties, a seed rate of 400-500 grams per hectare is generally recommended. Hybrid varieties require a lower seed rate.
Correct Answer
175-200 gm
Explanation
Hybrid Brinjal varieties typically require a lower seed rate of 175-200 grams per hectare compared to non-hybrid varieties. This is due to higher seed cost and germination potential.
Correct Answer
4-5 weeks
Explanation
Brinjal seedlings are usually ready for transplanting from the nursery to the main field after 4-5 weeks. At this stage, they have developed sufficiently strong root systems.
Correct Answer
White Brinjal
Explanation
White Brinjal varieties are often recommended for diabetic patients. Some studies suggest they may have properties beneficial for blood sugar management.
Correct Answer
Polyphenol Oxidase (PPO)
Explanation
The browning reaction observed when Brinjal is cut is primarily due to the activity of the Polyphenol Oxidase (PPO) enzyme. This enzyme oxidizes phenolic compounds in the presence of air.
Correct Answer
Cry1Ac
Explanation
Bt-Brinjal was developed by introducing the Cry1Ac gene from the bacterium Bacillus thuringiensis. This gene produces a protein toxic to certain insect pests, particularly the stem and fruit borer.
Correct Answer
Mahyco
Explanation
Bt-Brinjal was developed in India by the Maharashtra Hybrid Seeds Company (Mahyco). It was developed in collaboration with Monsanto and public research institutions.
Correct Answer
Copper (Cu)
Explanation
Copper (Cu) is highlighted as an essential micronutrient for increasing Brinjal yield. It plays a role in various enzymatic processes within the plant.
Correct Answer
Bumble bees and Honey bees
Explanation
Bumble bees and honey bees are the main pollinators for Brinjal flowers. Their activity is crucial for fruit set, especially in cross-pollinated scenarios.
Correct Answer
200 meters
Explanation
For certified seed production, an isolation distance of 200 meters is recommended for Brinjal. This helps prevent cross-pollination from other varieties.
Correct Answer
400 meters
Explanation
Foundation seed production of Brinjal requires a larger isolation distance of 400 meters. This ensures higher genetic purity compared to certified seed.
Correct Answer
Heterostyly
Explanation
Heterostyly is the condition found in Brinjal where flowers have styles of different lengths (long, medium, short, pseudo-short). This promotes cross-pollination.
Correct Answer
Long style
Explanation
Flowers with long styles exhibit the highest percentage of fruit set in Brinjal, typically ranging from 70-86%. Short and pseudo-short styles generally do not result in fruit development.
Correct Answer
Solanum incanum
Explanation
Solanum incanum is widely regarded as the wild progenitor species from which cultivated Brinjal (Solanum melongena) was domesticated. It shares many morphological similarities.
Correct Answer
Solanum torvum
Explanation
Solanum torvum is known for its resistance to bacterial wilt and is often used as a rootstock for grafting tomato and Brinjal. Grafting helps manage soilborne diseases.
Correct Answer
Very early ripening
Explanation
Pusa Purple Long is a widely cultivated Brinjal variety in India, known for its very early ripening characteristic. It is also resistant to wilt disease.
Correct Answer
BH-12
Explanation
The variety BH-12 is noted as being particularly suitable for preparing 'Bharta', a popular South Asian dish made from roasted Brinjal. It likely has fleshy pulp suitable for mashing.
Correct Answer
Leucinodes orbonalis
Explanation
Leucinodes orbonalis is the scientific name for the Brinjal Stem and Fruit Borer. This pest is a major constraint in Brinjal cultivation, causing significant damage to shoots and fruits.
Correct Answer
Larva
Explanation
The larval stage of the Stem and Fruit Borer is responsible for causing damage. The larvae bore into the tender shoots and fruits, feeding internally.
Correct Answer
Leaves
Explanation
The Hadda Beetle, both in its larval and adult stages, primarily feeds on the leaves of the Brinjal plant. They scrape the leaf surface, often leaving a characteristic 'skeletonized' appearance.
Correct Answer
Mycoplasma (Phytoplasma)
Explanation
Little Leaf disease of Brinjal is caused by a Mycoplasma-like Organism (MLO), now referred to as Phytoplasma. It leads to severe stunting and yellowing of leaves.
Correct Answer
Leafhopper
Explanation
Leafhoppers are the primary vectors responsible for transmitting the Mycoplasma (Phytoplasma) that causes Little Leaf disease in Brinjal. Managing leafhopper populations is key to controlling the disease spread.
Correct Answer
Phomopsis vexans
Explanation
Phomopsis Blight is caused by the fungus Phomopsis vexans. This disease can affect all parts of the plant, including leaves, stems, and fruits, causing significant yield losses.
Correct Answer
10-11°C
Explanation
For optimal storage, Brinjal fruits should be kept at a temperature range of 10-11°C with high humidity (around 92%). Lower temperatures can cause chilling injury.
