It is mainly cultivated for its high-quality edible oil and digestible protein. About 90% of the global groundnut production comes from Asia and Africa, where it is mostly produced by small holder farmers under rainfed conditions. The number of factors responsible for the low productivity of groundnut includes adverse climatic conditions, poor quality seeds, diseases and insects which significantly affect both the quality and production of groundnut. Among these insect pests are the major limiting factors to reduce pod yield. Thrips are the important sucking pests |

Abstract/Description: | Of the insect pests attacking groundnut crop, thrips is an important sucking insect pest. Field screening of 30 groundnut genotypes and released varieties against thrips, Scirtothrips dorsalis Hood under field condition was taken up at the Zonal Agricultural and Horticultural Research Station, Hiriyur, Chitradurga, Karnataka, India. Among them the six genotypes viz., JL-1067, TG-82, PBS 12200, UG-185, ICGV-91115 and GPBD-4 recorded least mean number of thrips (1.96, 2.13, 2.27, 2.43, 2.86 and 2.95/ top trifoliate leaves, respectively) with damage score of 3 recorded 10.2 to 19.20 and 11.20 to 18.40 per cent damage during 2018 and 2019, respectively and were grouped under resistant category. The four entries viz., K 1812, TCGS 1694, TG-86 and R 2013-1 with mean number of thrips of 3.12, 3.22, 3.33, 3.42 and/top trifoliate leaves, respectively with damage score of 5 recorded 21.00 to 23.20 and 22.00 to 23.40 per cent damage during 2018 and 2019, respectively and were grouped under moderately resistant category. The 11 entries viz., JL 977, TG-83, J 98, K-1809, JCG 4801, R 2001-2, KGL 1322, TCGS 1522, K-9, GKVK-5 and VG 13149 with mean number of thrips of 3.75, 3.78, 3.81, 3.85, 3.88, 3.94, 3.97, 4.09, 4.02, 4.02 and 4.20/ top trifoliate leaves, respectively with damage score of 7 recorded 31.20 to 39.80 and 31.60 to 39.80 per cent damage during 2018 and 2019, respectively and were grouped under moderately susceptible category. Whereas, the remaining nine genotypes viz., ICGV 07220, PBS-15044, G2-52, TCGS 1399, PBS 15022, ICVG 15327, J 95, K-6 and susceptible check TMV-2 with thrips population of 3.93, 3.98, 4.04, 4.24, 4.24, 4.32, 4.33, 4.39, and 4.41/top trifoliate leaves, respectively with damage score of 9 recorded 41.20 to 50.20 and 41.40 to 99.20 per cent damage during 2018 and 2019, respectively and were grouped under susceptible category. The correlation between thrips population and phenol content was highly significant and negatively correlated (r= -0.964 * * ). Whereas, thrips population and total sugars and amino acid were positively correlated and highly significant (r= 0.951 * * ) and (r= 0.942 * * ), respectively. |
