Abstract

Two field trails were carried out at a private farm in south Port-Said (Lat.31º15 N and long. 32º18 E) during summer 2014 and 2015 seasons, to evaluate ten imported sweet sorghum varieties viz, G.K. Arona, G.K. Coba, Roma, Cukorcirok, Honey, Atlas, Brandes, Umbrella, Tracy and SS301-1 and five lines viz Line 1 (G.K. Coba * G.K. Arona), Line 2 ( G.K. Arona * Roma), Line 3 (Roma * G.K. Arona), Line 4 (Roma * G.K. Coba) and Line 5 (G.K. Arona * Cukorcirok) for their resistance to pink stem borer (Sesamia cretica) and their productivity and quality criteria. The experimental design was randomized complete blocks with three replications. The obtained results of the separate seasons and their combined analysis indicated that all productivity and quality studied traits and the sensitivity to stem borer infestation as well were varied greatly among the fifteen genotypes including varieties and lines. Data also revealed that non of the studied 15 genotypes were immune to pink stem borer in both seasons and their combined data as well. Results obviously revealed that the new lines in this study exhibited a great successful in producing hybrid comination with high tolerance (less damage) to pink stem borer (Sesamia cretica), distinctive and with superior productivity and quality features.
