Guntur Sannam
Guntur Sannam or Capsicum annuum var. longum, is a variety of chili pepper that grows in the districts of Guntur, Prakasam (Andhra Pradesh), Warangal (Telangana), and Khammam in India. It is registered as one of the geographical indications of Andhra Pradesh (pursuant to Geographical Indications of Goods (Registration and Protection) Act, 1999). Origin 
The Guntur Sannam pepper belongs to the species Capsicum annuum. It is a commercial crop used as a condiment and culinary supplement. India stands first place in the production of chilies. The state of Andhra Pradesh leads in its production, providing 46% of all chilies produced in India. The government of Andhra Pradesh started a regional research station at LAM near Guntur around 30 years ago, which also studies the uses of chili. Etymologically, the name 'Guntur Sannam' has its origin in Telugu, and indicates two facts: the origin of the fruit, and more importantly, the strong antecedents arising from Andhra Pradesh. Guntur has been associated with chilies for decades, and hence the prefix 'Guntur' for the name of this chili. The word 'Sannani' in Telugu means 'thin'. Characteristics 
The Guntur Sannam chili's unique characteristics have brought it international acclaim. The Sannam chili is traded as an S4 type chili and is mainly used for its pungency and the extraction and derivation of capsaicin, which is an active component in chilies that gives them their hot qualities.

The Guntur Sannam chili has specific requirements in its means of production for attaining an optimum level of production. Guntur Sannam crops are highly prone to disease, and therefore need special care and attention to ensure a healthy, pest-free yield. Geographical area of production 
The Guntur Sannam chili is cultivated, processed, and made available mainly from the Guntur district of Andhra Pradesh. It is also grown in neighboring regions such as the districts of Prakasam, Warangal, and Khammam. The Guntur Sannam chili requires a warm and humid climate for its growth, and dry weather during its period of maturation. The crop can be grown at altitudes up to 2,100 meters above sea level.
