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 2017, which is the year of AICRIP testing, 48 varietal trials, 1 screening nursery and 5 hybrid rice trials were conducted as 813 experiments at 123 locations (45 funded, 78 voluntary centres) across 25 states and 2 union territories in all the 7 zones of the country.
- Two Hundred and fifty three entries wereid entified as promising for different states and ecologies.
- A totally 95 hybrids were evaluated in four hybrid rice trials viz., IHRT-E, IHRT- ME, IHRT-M, IHRT-MS, in 27-33 different locations representing different agro-climatic regions of the country. 11 hybrids were found to be promising.
- The Varietal Identification Committee identified 5 hybrids and 18 varietal entries for release in different states.
- Of the 390 entries evaluated in INGER observation nurseries at 45 locations, 32 were found to be promising based on phenotypic acceptability and yield.
- Breeder seed production of rice varieties and parental lines of hybrids as per DAC indents was organized at 38 centers across the country, involving 271 varieties and parental lines of eight hybrids. A total production of 78,331 quintals of breeder seed was achieved
