A book was written on Brinjal or egg plant (Solanum melongena L.) research experiment to know some objective like (i)To estimate the magnitude of heterosis for fruit yield and its components characters. (ii) To study the general as well as specific combining ability and variances. (iii)To identify the good general as well as specific combiners for use in future breeding programme. With help of studying of heterosis and combining ability. Characters like Days to fifty per cent flowering, Plant height at harvest (cm), Number of branches per plant at harvest, Fruit length (cm), Fruit diameter (cm), Average fruit weight (g), Number of fruits per plant, Fruit yield per plant (kg),Total phenol content (mg/100g), Total Soluble Solids (%).
