Abstract: Field experiment was conducted at AICRP on Vegetable Crops of OUAT, Bhubaneswar during Rabi, 2017-18 to study the performance of local landraces of brinjal of Odisha. Fifty two local landraces of brinjal including four check varieties were grown by adopting Randomized Block Design replicated twice. The results revealed significant variations among the traits. The plant height varied from 65.68 cm (BBSR-200) to 161.44 cm (Utkal Jyoti), while primary branches plant-1 from 2.40 (Nayagarh spiny brinjal) to 5.70 (BBSR-114). Invariably, days to 1st and 50% flowering varied from 42.50 days (BBSR-145-1) to 64.30 days (Jammusahi local) and 51.10 days (BBSR-11-4) to 71.90 days (Jammusahi local), respectively. Fruit length varied from 7.41cm (BBSR-09-8-1) to 21.10 cm (Arka Nidhi) while that of fruit breadth 9.67cm (selection from Hajari local) to 31.40cm (Keonjhar local-1). Maximum fruits plant-1 was recorded in Selection from BBSR-192-1 (40.59). Similarly, average fruit weight varied significantly among the total genotypes from 50.85 g (BBSR-114) to 233.97 g (Jammusahi local). Incidence of wilt revealed significant variations among local landraces which varied from 0.00% (BBSR-08-2, BBSR-09-4, BBSR-09-16, BBSR-10-25, BBSR-10-26, Selection from BBSR-192-1, Selection from BBSR-145-1, Jammusahi local) to 22.76% (Dhenkanal local). Total fruit yield plant-1 varied significantly ranging from 865.80 g (BBSR-195-2) to 3045.70 g (Selection from BBSR- 192-1).Thus, the availability of wide variability among the local landraces provided enough opportunities for their improvements in brinjal. Selection from BBSR-192-1 was identified as best landrace having highest fruits plant-1 with total yield plant-1 having resistance to bacterial wilt. Similarly, Jammusahi local may be taken as a parent for development of large green round fruited genotype with resistance to bacterial wilt in further crop improvement programme.
