Step 1: Understanding the Concept:
Identifying crop cultivars developed by major research institutes is essential for agricultural exams.
The Indian Institute of Vegetable Research (ICAR-IIVR), located in Varanasi, develops superior vegetable varieties prefixed with "Kashi".
Step 2: Detailed Explanation:
Kashi Sheetal is a highly popular, high-yielding variety of Cucumber (Cucumis sativus) developed by ICAR-IIVR, Varanasi.
This variety is specifically bred for its tolerance to low-temperature stresses, making it suitable for early spring sowing when temperatures are relatively low.
The vines of Kashi Sheetal are moderately vigorous with medium-sized, green, shiny, and attractive fruits that are free from bitterness.
It yields approximately \( 200 - 250 \, \text{q/ha} \) of marketable cucumbers under optimal management.
Its tolerance to colder climates enables farmers to harvest early in the season, capturing premium market prices when standard varieties cannot be easily cultivated.
Step 3: Final Answer:
Kashi Sheetal is a famous variety of Cucumber.
