Four high oil yielding groundnut lines, identified in ‘High Oil’ project, were promoted to Advance Varietal Trials (AVT) based on their superior performance over best checks during two years of evaluation. The mean oil yield of these lines varied from 922 to 978 kg/ha, which is an increase by 10-17% over the best check. Pod yield increase was 16-20% over best check.
This was announced at the recently concluded workshop of All India Coordinated Research Project on Groundnut (AICRP-G). These groundnut lines were evaluated in 26 locations, across five groundnut growing zones of the country.
During 2013, seven high oil yielding varieties were recommended by Junagadh Agricultural University (JAU), Tamil Nadu Agricultural University (TNAU) and Acharya NG Ranga Agricultural University (ANGRAU) for testing under AICRP-G. Four of them, ICGV 05155, ICGV 06420, ICGV 03042 and ICGV 03043 were promoted for Advance Trials in Zone V. Interestingly, of the six test entries promoted in Zone V, four were outputs from this project.
Promotion of four out of seven recommended varieties, a promotion success percent of >50% is a remarkable feat. The accomplishment was possible through concerted efforts of all project partners since 2011.
It began with initial selection of 47 best high oil yielding lines from a collection of 150 advance breeding lines available at ICRISAT’s groundnut breeding unit, followed by planning of multi-location trials, rigorous and efficient screening of test lines at JAU, TNAU, ANGRAU, Directorate of Groundnut Research, and ICRISAT for four seasons from 2011 onwards, systematic execution of the trials, and proper collection of data and subsequent data analysis leading to identification of best performing lines at each location.
First-ever evaluation trial in India with high oleate groundnut lines
The first-ever evaluation trial in India with high oleate groundnut lines developed under this project is underway during 2014-15. High oleate groundnut has at least two marketable benefits: health benefits to consumer and extended shelf life of groundnut and its products. A total of 27 introgression lines with oil content varying from 53-58%, and oleic acid content varying from 67-83% were identified.
This year’s annual workshop assumes significance for two other initiatives: (a) For the first time, identification of three MABC derived disease resistant groundnut lines, ICGV 13193, 13200 and 13206 for superior pod yield coupled with rust resistance from UAS-Dharwad, Karnataka was reported. ICRISAT shared 20 introgression lines for foliar fungal disease resistance with UAS-Dharwad and TNAU in 2014. (b) A significant move towards ‘demand-driven innovation’ is the constitution of a new trial to evaluate Indian groundnut varieties for their quality attributes and export-worthiness. In recent years, use of groundnut for food and confectionery is increasing in India. Thus, a new trial was constituted to identify varieties that meet domestic and export industry needs. Biochemical properties that contribute to quality of groundnut and its products will be evaluated.
The AICRP-G workshop was held on 12-14 April at Agricultural Research Station, Kadiri, Andhra Pradesh.
