The study was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Salna, Gazipur- 1703, during October, 2000 to March 2001 to find out the resistant source of diseases and insects of sweet pepper under field condition. The incidence of thrips was calculated and grading was done slightly modified on the basis of mean percentage plant infection as highly resistant (o %), resistant (1-5 %), moderately resistant (6- 20 %), moderately susceptible (26-50 %) and susceptible (51-100 %). From the field performance study it was evident that the genotypes SP011 was highly resistant whereas, SP002, SP006, SP010 and SP012 were observed to be resistant to Thrips. In case of Mites, none of the genotypes was highly resistant but SP002, SP006, SP007 and SP011 were categorized as resistant. Incidence of yellow leaf curl virus, potato virus-Y and fusarium wilt were not severe and graded as resistant to highly resistant under field conditions. Yield per hectare was the highest (27.00 t) in SP009 followed by SP006 (26.24 t/ha) and it was the lowest in SP002 (5.06 t/ha). Download
