Abstract:
Evaluation of segregating populations for stem borer resistance is one of the best ways to select RILs that mitigate adverse effect of stem borer. The present study was initiated to evaluate sorghum segregating populations, estimate the genetic variability, and identify the best performing genotypes for yield and stem borer resistance. The study was conducted during 2017 at Forage Research area of Department of Genetics & Plant breeding CCS Haryana Agricultural University, Hisar. F₃ population was obtained from crossing two parents HJ513 (susceptible) and IS 2205(resistance) with contrasting morphological traits for stem borer resistance. A total of 202 RILs were evaluated using augumented design. RILs 3, 4, 13, 21, 26, 54, 55, 56, 60, 83, 85, 86, 89, 90, 91, 96, 99, 100, 104, 108, 109, 118, 119, 189, 129, 139, 151 were recorded as top performing among F₃ population for green fodder yield. The less no. of dead heart and stem-tunneling were registered in RIL s 47, 48, 49, 72, 74, 144, 154, 155, 160, 166, 169. High heriatability coupled with genetic advance as percent of mean was noted for green fodder yield and plant height. Good pogress is expected from selection of morphological traits for borer resistance in sorghum population. These RILs appear well suited for further specific area for stem borer resistance breeding and research.
