Flavour
Basmati rice has a typical pandan-like (Pandanus fascicularis leaf) flavour caused by the aroma compound 2-acetyl-1-pyrroline.[1]
Varieties and hybrids
A number of varieties of basmati rice exist. Traditional types include Basmati-370, Basmati-385 and Basmati-Ranbirsinghpura(R.S.Pura), while hybrid basmati varieties include Pusa Basmati 1 (also called 'Todal', because the flower has awns). Fragrant rices that are derived from basmati stock but are not considered true basmati varieties include PB2 (also called sugandh-2), PB3 and RH-10.
Scientists at Indian Agricultural Research Institute, Delhi took the traditional basmati and genetically modified it to produce a hybrid which had most of the good features of traditional basmati (grain elongation, fragrance, alkali content) and the plant was a semi-dwarf type. This basmati was called Pusa Basmati-1. PB1 crop yield is higher than the traditional varieties (up to twice as much).
List of approved varieties

Detection of adulterated strains
Difficulty in differentiating genuine traditional basmati from pretenders and the significant price difference between them has led fraudulent traders to adulterate traditional basmati. To protect the interests of consumers and trade, a PCR-based assay similar to DNA fingerprinting in humans allows for the detection of adulterated and non-basmati strains. Its detection limit for adulteration is from 1% upwards with an error rate of ±1.5%. Exporters of basmati rice use 'purity certificates' based on DNA tests for their basmati rice consignments. See Protocol [1]and [2]. Based on this protocol, which was developed at the Centre for DNA Fingerprinting and Diagnostics, Labindia, an Indian company has released kits to detect basmati adulteration.[5]
Patent battle
In September 1997, a Texas company called RiceTec won a patent (U.S. Patent No. 5,663,484) on "basmati rice lines and grains." The patent secures lines of basmati and basmati-like rice and ways of analyzing that rice. RiceTec, owned by Prince Hans-Adam ofLiechtenstein, faced international outrage over allegations of biopiracy. It had also caused a brief diplomatic crisis between India and United States with India threatening to take the matter to WTO as a violation of TRIPS which could have resulted in a major embarrassment for the United States.[6] Both voluntarily and due to review decisions by the United States Patent and Trademark Office, RiceTec lost or withdrew most of the claims of the patent, including, most importantly, the right to call their rice lines "basmati."[7] A more limited varietal patent was granted to RiceTec in 2001 on claims dealing with three strains of the rice developed by the company.[8]
