Description The present investigations were carried out during kharif
1998 at the Department of Agricultural Entomology, Post Graduate
Institute, Mahatma Phule Krishi Vidyapeeth, Rahuri (M.S.) with
objectives to select the better sources of resistance in sorghum to
shoot fly, Atherigona soccata Rondani and to determine the
mechanism of resistance by studying the morphological (physical)
plant characters associated with shoot fly resistance. Thirty five
sorghum entries along with one resistant check and two susceptible
checks were selected and statistically laid out, field trial was conducted in kharif 1998. The incidence of shoot fly (dead hearts) was
recorded to find out less, moderately and highly susceptible entries.
From the percentage of dead hearts, seven entries namely
RSE 9715, RSE 9727, RSE 9745, RSE 9737, RSE 9714, RSE 9741, RSE
9728 were found to be less susceptible, four entries namely RSE 9735,
RSE 9759, RSE 9719 and RSE 9710 were highly susceptible and the
remaining twenty four entries were moderately susceptible to
shoot fly.
The egg laying was observed to be less on less susceptible
entries and resistant check than that of highly susceptible entries and
susceptible checks. The positive correlation (r = 0.864**) was
observed between egg laying and dead hearts.
Among the morphological (physical) plant characters, leaf
breadth, leaf area, green leaf colour and spreading growth habit of
the plants had a positive correlation with egg laying. On the other
hand leaf length and breadth ratio, trichomes, yellowish green leaf
colour, glossiness and erect growth habit of plants exihibited
negative correlation with egg laying.
