Heterosis is yield and yield components in eggplant (solanum melongena L.)

Pachiyappan, R., Saravanan, K and Kumar, R

The study was carried out with seven lines and three testers to estimate the heterosis for eight traits viz., days to first flowering, plant height, number of branches per plant, number of fruits per plant, fruit length, fruit girth, fruit weight and fruit per plant. Heterosis to the extent of 79.99 and 54.11 per cent over the mid parent and better was recorded fruit yield per plant respectively. The parent KKM-1 found to be very promising which exhibited higher heterosis for fruit yield per plant. Two hybrids viz., CO-2 x KKM-1 and Annamalai x KKL-1 were identified as promising for fruit yield and other desirable traits which may be useful for exploitation of hybrid vigour in egg plant.
