Combining ability analysis in brinjal genotypes indicated significant genotypic and environmental variations for all the 15 characters studied. Both general combining ability (GCA) and specific combining ability (SCA) variances showed significant interactions. Genotypes Palamedu Local (L5), Alagarkovil Local (L4), Melur Local (L6) and Annamalai (T1) were found to be good general combiners, and the crosses L3 x T3 (Kariapatty Local x Punjab Sadabahar), L8 x T1, (Nilakottai Local x Annamalai), L4 x T1 (Alagarkovil Local x Annamalai), L6 x T2 (Melur Local x KKM 1), L7 x T3 (Keerikai Local x Punjab Sadabahar) and L7 x T2 (Keerikai Local x KKM 1) were identified as good specific combiners for fruit yield and other related traits. These hybrid combinations can be used for commercial exploitation for fruit yield in brinjal.Keywords

Anthracnose caused by complex of Colletotrichum species is an economically important disease of chilli. The study involved 132 genotypes grown under field conditions. Among the genotypes evaluated, fifteen genotypes were moderately resistant to anthracnose with fairly high yield. In the order of merit, the genotypes were CA 177 (10.74%), Paramakudi 1 (16.64%), F 507 (17.17%), Bird’s eye chilli (17.85%), Kadaladi 1 (19.70%), Ramnad local (20.64%), CO 1 (20.82%), TA/CA/ 10 (21.56%), CA 166 (21.94%), CA 188 (22.29%), Paramakudi 2 (22.45%), CA 13/6 (23.42%), Chilli CO hybrid 1 (24.36%), IC 342465 (24.68%) and CA 165 (25.70%). whereas, 40 genotypes were susceptible with PDI ranging from 26.30 to 50.69 per cent and majority of the genotypes (77nos) were found to be highly susceptible to anthracnose with per cent disease index ranging from 51.81 to 96.42 per cent. The moderately resistant genotypes identified in the present investigation will serve as donors or source of resistance for anthracnose.Keywords
