Screening for finding resistant sources among little millet entries/genotypes against shootfly in Ranchi, Jharkhand

Kamal Kartik Kenny Kundra, MK Chakravarty and Alka Kumari

A field trial was conducted at little millet research plot of Birsa Agricultural University, Kanke, Ranchi during Kharif season of 2017, in order to screen out the resistant little millet genotypes against the shootfly, a total number of 19 genotypes i.e. DLM95, WV126, DLHLT28-4, OLM217, WV167, IIMR LM7012, OLM233, IIMR LM7162, TNPSu183, GPUL4(MLT9), TNPSu186, GPUL5 252, WV 125, RLM 37, RLM 367, JK 8, OLM 203 and BL 6 including the susceptible check BG 1, against shootfly. The experiment was laid out in randomized block design with three replications.The genotype IIMR LM7012 (10.78%) recorded the lowest percentage of plants bearing shootfly eggs and it remained at par with BG 1 (12.77%) which were however, not better than DLM95 (16.26%). The genotype IIMR LM7012 recorded the lowest deadhearts per cent and remained at par with BG 1, DLM95, OLM217, BL 6 and DLHLT28-4 in which the deadheart counts were 13.35, 14.02, 16.17, 17.42 and 17.65 per cent, respectively. the genotypes IIMR LM7012 though recorded significantly more productive tillers per plant (3.36) but remained at par with BG 1 (2.83), WV 125 (2.13), GPUL5 252 (2.16), OLM217 (2.23), TNPSu186 (2.26), BL 6 (2.30), and DLHLT28-4 (2.40). The genotypes IIMR LM7012 recorded significantly more productive tillers per plant (3.36) but remained at par with BG 1 (2.83), WV 125 (2.13), GPUL5 252 (2.16), OLM217 (2.23), TNPSu186 (2.26), BL 6 (2.30), and DLHLT28-4 (2.40). The genotypes IIMR LM7012 though recorded significantly more productive tillers per plant (3.36) but remained at par with BG 1 (2.83), WV 125 (2.13), GPUL5 252 (2.16), OLM217 (2.23), TNPSu186 (2.26), BL 6 (2.30), and DLHLT28-4 (2.40). And The cultivar OLM 203, with 27.31 per cent deadhearts, was considered to be the most susceptible one against shootfly.
