India developed two genome-edited rice varieties — DRR Dhan 100 (Kamala) and Pusa Rice DST1 and is set to release Pusa Rice DST1 for commercial production in the upcoming rabi season.
About Pusa DST Rice 1:
It is derived from MTU1010, which is suitable for rabi season in southern states.
It is developed by Indian Council of Agricultural Research (ICAR)-Indian Agricultural Research Institute (IARI), New Delhi.
Properties: The edit in its genome targets the Drought and Salt Tolerance (DST) gene, with the aim of improving the plant’s ability to cope with drought and salt-affected soils.
It is expected to be grown in Andhra Pradesh, Telangana, Karnataka, Tamil Nadu, Kerala, Chhattisgarh, Odisha, Madhya Pradesh, Maharashtra, Jharkhand, Bihar, Uttar Pradesh and West Bengal.
About DRR Dhan 100:
It is also called Kamala variety.
It was developed by ICAR-Indian Institute of Rice Research, Hyderabad, from the popular Samba Mahsuri (BPT 5204) variety.
Scientists edited a gene involved in cytokinin metabolism, with the aim of increasing the number of grains produced by each panicle.
Properties: The resulting variety is said to mature about 20 days earlier than Samba Mahsuri, in around 130 days, and has a stronger stalk that is less prone to lodging, or falling over.
