Eggplant (Solanum melongena L.) is an important solanaceous crop of tropics and sub-tropics, having high production potential, and also a rich source of nutrients, particularly, carbohydrates, proteins, dietary fibre and vitamins like thiamin, niacin, pantothenic acid and folic acid, minerals like calcium, iron, potash, zinc, copper and manganese as well as bioactive compounds. However, eggplant is available in diverse shape and colour and consumer preference varies and the nutrient composition is different. In this investigation, we worked out the proximate nutrient compounds (on dry weight basis) and the bioactive compounds (on a fresh weight basis) in twenty diverse eggplant genotypes varying in colour and shape.  Moisture content in the fruits ranged from 71.54 to 91.36%, while carbohydrate content from 2.80 to 6.82%, crude protein 16.98 to 31.85%, nitrogen 2.49 to 4.35%, phosphorous 0.29 to 0.51%, potassium 1.65 to 4.54%, calcium 0.83 to 0.35%, iron 106.21 to 235.34 mg/kg, manganese 89.01 to 245.54 mg/kg, copper 18.73 to 98.56 mg/kg and zinc 60.73 to 75.77 mg/kg, each on dry weight basis. Biochemical parameters like total soluble solids (TSS) ranged from 1.27 to 3.94 °Brix, total sugar content 2.26 to 4.65%, ascorbic acid 0.66 to 3.53 mg/100 g, total anthocyanin content 0.35 to 18.85 mg/100 g FW, total chlorophyll 0.11 to 2.70 mg/100 g FW, total phenol 1.03 to 15.65 mg catechol equivalent/100 g FW, total antioxidant 1.16 to 2.26 µmol Trolox equivalent/g FW and radical scavenging activity 50.52 to 96.48%. Proximate nutrients were highest in Pusa Uttam, Pant Rituraj and BRBL-01, quality parameters in BRBL-07 and 71-19, while bioactive compounds were highest in Pant Rituraj, Pusa Purple Long, Pusa Purple Cluster and BRBL-01. These genotypes may be utilized in future breeding programmes for developing effective and nutritive cultivars.

Twenty-one brinjal hybrids along with their seven parents and one hybrid check were evaluated in three seasons, viz., autumn-winter, rainy and summer for the study of genotype x environment interaction for different traits and identification of the stable genotypes. Stability analysis revealed that the variance due to genotypes was highly significant for all the characters studied when tested against pooled deviations except days to 50% flowering and days to 1st harvest. Likewise, variance due to E + (G × E) was highly significant for all characters but significant for days to 1st harvest. The genotypes × environments (linear) component for days to 50% flowering and days to 1st harvest were non-significant when tested against pooled deviation which suggested the preponderance of non-linear component as compared to linear component for both these characters. Rajendra Baigan-2 x BRBL-02, Rajendra Baigan-2 x BRBL-01, Rajendra Baigan-2 x BRBL-04, Muktakeshi x BRBL-01, Muktakeshi x BRBL-04, BRBL-02 x BRBL-04, Swarna Mani x BRBL-01, BRBR-01 x BRBL-01 and BRBR-01 x BRBL-04 were identified as stable hybrids and BRBL-01 and BRBL-04 were stable parents in terms of yield/ plant. BRBL-02 x BRBL-04 was stable in terms of total sugar content, total anthocyanin content and total phenolics content. These genotypes may be utilized for planting throughout the year with good performance and utilized in breeding programmes for developing stable genotypes.
