Research achievements

since 1968, more than 1088 varieties including 72 hybrids have been released throught multi location testing for various agro-ecological systems prevalent across the country. Of these varieties, 503 are for irrigated areas, 133 for rainfed uplands, 194 for rainfed low lands, 44 for semi deep and 18 for deep water situation, 51 for high altitudes, 42 for saline and alkaline areas, 10 for aierobic, 19 for boro and 74 aromatic long and short grain varieties were released. More than 66 varieties have been developed by the Directorate of which 44 are central releases and the rest are released in different states. Globally 19 varieties released through AICRIP are being cultivated in 25 other rice growing countries.                                 

 

Significant achievements during 2015-2016

 

New Varieties and Hybrids released

 

Forty two varieties and four hybrids were released during 2015-16 by Central Sub Committee on Crop Standards, Notification and Release of Varieties (CSCCSN & RV) and State Varietal release Committee (SVRC). Central Sub Committee on Crop Standards, Notification and Release of Varieties released 15 varieties and three hybrids (KRH 4, KPH 460 and ADV 8301). The State Varietal Release Committees released 27  varieties;  for  Andhra  Pradesh  (1),  Gujarat (2), Karnataka (2), Kerala (5), Maharashtra (1), Madhya  Pradesh  (1),  Manipur  (1),  Telangana (3) Uttarakhand (4), and West Bengal (7). These high yielding varieties (HVYs) were released for cultivation in different ecologies viz., irrigated, aerobic, basmati, rainfed shallow low land, deep water and coastal saline areas. Many of these varieties  are  resistant/moderately  resistant  to biotic stresses.

 

Crop Improvement 

  • During   the   year   2015,   42   varietal,   one screening nursery and three hybrid rice trials were conducted in 682 experiments at 160 locations in 27 states and 2 union territories covering all the 7 zones in the country. In addition, 14 INGER nurseries involving 666 entries were tested at 58 centers.
  • Forty two varieties and four hybrids were released during 2015-16 by Central Sub Committee on Crop Standards, Notification and Release of Varieties (CSCCSN & RV) and State Varietal release Committee (SVRC).
  • The     varietal     identification     committee identified 14 varieties and 3 hybrids for release in different states across ecologies.
  • Of the 666 entries were tested in 14 INGER nurseries, 61 were found promising based on phenotypic acceptability and yield for multi location testing.
  • Breeder seed production (BSP) of 217 rice varieties and parental lines of 8 rice hybrids was organized at 43 centers across the country as per the DAC indents. A total production  of  7757.42  quintals  of  breeder seed  was  achieved  against  the  target  of 4328.42  quintals,  thus  marking  79%  more than the indented quantity. At IIRR center, 11 varieties and A,B and R lines of DRRH-3 were included in breeder seed production with a total production of 160.82 quintals against the target of 87.30 quintals
