ICAR-IIRR releases four new rice varieties
The four new rice varieties namely DRR Dhan 53, DRR Dhan 54, DRR Dhan
55 and DRR Dhan 56 are resistant to bacterial blight to a major extent.
Hyderabad-based research organization, Indian Institute of Rice Research
(ICAR-IIRR) has released four new rice varieties namely DRR Dhan 53, DRR
Dhan 54, DRR Dhan 55 and DRR Dhan 56 recently.
Fine-grain rice varieties like Samba Mahsuri are usually affected due to a
bacterial disease, Xanthomonas oryzae pv. oryzae which in turn reduces yield
of the crop. To curb this type of infections, scientists from ICAR have
developed a novel durable bacterial blight resistant, DRR Dhan 53 which is of
high-yielding, fine-grain rice variety that has four major bacterial resistant
genes introgressed through marker assisted selection.
The variety has been released for cultivation in irrigated and bacterial blight
endemic areas of Andhra Pradesh, Telangana, Chhattisgarh, Karnataka, Tamil
Nadu, Jharkhand, Odisha, Bihar, Gujarat and Maharashtra.
