The resultant twenty one single crosses along with ten parents and two standard checks (Arka Anand and Mahy Hari) were evaluated in RBD for twenty yield and yield contributing traits. The analysis of variance of the trial conducted revealed that the replication mean sum of squares due to parents and hybrids were non significant for all the characters studied, which means there is no environmental error in controlling these characters. The mean performance of crosses viz., RCBG-4 x Shyamala (2.73 kg), RCBG-2 x Bhagyamathi (2.66 kg), RCBG-1 x Bhagyamathi (2.63 kg), RCBG-7 x Shyamala (2.43 kg) and RCBG-1 x Shyamala (2.42 kg) were significantly superior to the best commercial check Mahy Hari (1.89 kg). These hybrids may be subjected to multilocational and multiseasonal trials for their release for commercial cultivation. origin. The region across India and Indo-china is considered the centre of diversity for brinjal (Vavilov, 1951). Introduction Egg plant or Brinjal (Solanum melongena L., 2n = 2x = 24) belonging to the family Solanaceae, is one of the most commonly grown, important and popular vegetable crops in India. It is often referred as poor man’s crop (Sharma et al., 2004), vegetable of masses (Patel and Sarnaik, 2003) and king of vegetables. The cultivated brinjal is of Indian India is major producer of brinjal in the world. In India, eggplant occupies an area of 0.73 million hectares with an annual production of 12.515 million tonnes and productivity stands at 18.9 MT/ha. The major brinjal growing states are West Benghal, 32 Int.J.Curr.Microbiol.App.Sci (2021) 10(02): 32-45 Odisha, Gujarat, Madhya Pradesh, Bihar, Chhattisgarh, Andhra Pradesh, Maharashta, Karnataka and Telangana. In Telangana, it is grown over an area of 20,176 acres with a production of 2,36,878 tonnes and productivity is 19.46 MT/ha (Dept. of Horticulture, Telangna, 2019-20). The unripe fruits of brinjal contain carbohydrate, protein, ascorbic acid, Ca, Mg, Fe, P, vitamin B6, niacin, pantothenic acid, vitamin A and vitamin K. It is very low in calories and fats but rich in soluble fiber content. The peel has significant amounts of phenolic flavonoid phyto-chemicals called anthocyanins. They are also known to have alkaloid solanin in roots and leaves. Copper content, aminoacid content and polyphenol oxidase activity were highest in purple brinjal where as Fe, potassium and chloride content were highest in green cultivars. hybrid combinations. Earlier, egg plant breeding was relied both on mass selection and pure line selection from land races for the development of improved varieties. Brinjal, being native to India and often cross pollinated crop, possesses considerable diversity for plant type, fruit colour, fruit shape, fruit size, yield and other quality traits (Ravali et al., 2017), which offers much scope for improvement through heterosis breeding. Heterosis breeding has become the widely used breeding method could enhance its quality and productivity without sacrificing the consumer’s choice. Exploitation of hybrid vigour in brinjal is commercially possible (Bavage et al., 2005; Prabhu et al., 2005; Dharwad et al., 2011) due to manifestation of high heterosis and other important characters, ease of handling the flowers during artificial emasculation and pollination, and realization of high number of hybrid seed per effective pollination. The estimation of heterosis for yield and its component characters would therefore, useful to judge the best hybrid combination for exploitation of superior hybrids. Several research workers reported the importance of genetic diversity and heterosis in crops (Saidaiah et al., 2010, 2012, Raghu et al., 2012, Ravindrakumar et al., (2012), Sunil et al., (2013), Arun Kumar et al., (2016), Rajasekhar reddy et al., 2017, Ravali et al., 2017, Triveni et al., (2017), Pidigam et al., 2019 and Srivatsava et al., 2019). Keeping in view of the above discussed aspects, the present investigation was carried out with an objective of studying the performance of hybrids for yield and yield related traits in field conditions. Brinjal is grown for its immature, tender and unripe fruits which are used in variety of ways as cooked vegetable in curries. It has got much potential as raw material in pickle making and dehydration industries (Singh et al., 1963). The fruit is employed as cure for toothache. It has also been employed as excellent remedy for those suffering from liver complaints. Fruit is used as cardiotonic, laxative muturant and reliever of inflammation. White brinjals are good for diabetic patients (Singh et al., 1963). Other medicinal uses of brinjal include treatment of diabetes, asthma, cholera, bronchitis and dyspepsia. Fruits and leaves are administered to lower blood cholesterol levels. A number of cultivars are under cultivation depending upon the yield, consumer preference about the colour, size and shape of the fruit. But it is not possible to have one common cultivar to suit different localities and local preferences. It is therefore required to improve the locally preferred cultivars for yield and adaptation or development of new Materials and Methods The seven genotypes viz., RCBG-1, RCBG-2, RCBG-3, RCBG-4, RCBG-5, RCBG-6 and RCBG-7 having high genetic divergence and desirable characters were selected as lines and 33 Int.J.Curr.Microbiol.App.Sci (2021) 10(02): 32-45 three improved locally popular varieties viz., Bhagyamathi, Gulabi and Shyamala were selected as testers and were crossed in line x tester mating fashion during rabi, 2016. The resultant twenty one single crosses along with ten parents and two standard checks (Arka Anand and Mahy Hari) were evaluated in RBD following Panse and Sukatme, 1957 ANOVA for twenty yield and yield contributing traits at PG students research farm, College of Horticulture, Rajendranagar, Hyderabad in order to obtained information on the mean performance. Seeds of ten patents, twenty one hybrids and two commercial checks were sown on 25th January, 2017 in plug trays and thirty two days old seedlings were transplanted in the main field. In each replication each genotype was grown in a plot of 1.8 x 3.5 m2 consisting of three rows, accommodating 7 plants in each row. Row-to- row spacing of 60 cm and plant-to-plant spacing of 50 cm was maintained. The recommended package of practices was followed to raise a successful crop and necessary prophylactic plant protection measures were carried out to safeguard the crop from pests and diseases. and total phenols content(mg/100g) are presented in Table 4.1. The replication mean sum of squares due to parents and hybrids were non significant for all the characters studied, which means there is no environmental error in controlling these characters. The treatment mean sum of squares due to parents and hybrids for all the characters under study were highly significant, indicating the presence of significant variation among the characters studied. The results are in line with the reports of Ravali et al., 2017, Saidaiah et al., 2010, 2012, Raghu et al., 2012, Ravindrakumar et al., (2012), Sunil et al., (2013), Arun Kumar et al., (2016), Rajasekhar reddy et al., 2017, Triveni et al., (2017), Pidigam et al., 2019 and Srivatsava et al., 2019. In lines, the mean values of plant height were ranged from 58.45 cm in RCBG-6 to 77.40 cm in RCBG-4 with an average of 69.97 cm whereas, in testers, it was ranged from 63.49 cm in Shyamala to 78.16 cm in Gulabi with an average of 70.26 cm. Among hybrids, the cross RCBG-4 x Bhagyamathi shown highest plant height i.e. 89.32 cm followed by RCBG3 x Gulabi (89.07 cm) and the lowest plant height was recorded in RCBG-3 x Bhagyamathi (62.60 cm) with an average mean of 78.45 cm (Table 2). Out of 21 hybrids, nine hybrids viz., RCBG-4 x Bhagyamathi (89.32), RCBG-3 x Gulabi (89.07), RCBG-7 x Gulabi (88.33), RCBG-5 x Gulabi (85.39), RCBG-6 x Gulabi (85.22), RCBG-4 x Gulabi (85.21), RCBG-7 x Bhagyamathi (83.10cm), RCBG-1 x Shyamala (82.85cm) and RCBG-2 x Gulabi (82.12cm) were recorded more plant height than best check Arka Anand (80.42cm). The present results are in close conformity with the earlier reports of Roy et al., (2009), Kalaiyarasi et al., (2017) and Patidar et al., (2017).
