dc.description.abstract | The research projec t entitled “Evaluation of hybrids for yield and quality in chilli ( Capsicum annuumL.)” was conducted at Department of Olericulture, College of Agriculture, Vellayani during 2015-16. The objective of the study was to evaluate the yield and quality characters of F1 hybrids of chilli. The experimental material consisted of five parents viz., CA 3 (P1), CA 5 (P2), CA 6 (P3), CA 8 (P4) and CA 32 (P5) and 10 F1s produced in diallel mating design excluding reciprocals. The hybrid Arka Harita and variety Vellayani Athulya were used as checks for the estimation of standard heterosis. The experiment was laid out in Randomized Block Design (RBD) with 17 treatments and three replications for two seasons viz., May 2015 to September 2015 and October 2015 to February 2016. Analysis of variance showed significant differences among the treatments for almost all characters studied. Among the hybrids P4 x P5 recorded the highest fruit weight (9.66 g), flesh thickness (2.81 mm), green fruit yield plant-1 (962.93 g), dry fruit yield plant-1 (144.05 g) and yield plot-1 (27.72 kg). Maximum fruits plant-1 was recorded in the hybrid P3 x P4(148.76), fruit length in P1 x P5(12.61 cm) and fruit girth in P3 x P5 (4.43 cm). Among the parents P5 recorded highest fruit weight (6.73 g), flesh thickness (2.61 111m), green fruit yield plant-1 (448.70 g), dry fruit yield plant-1 (79.98 g) and yield plot-1 (12.91 kg). The hybrid P2 x P5 had high quality parameters like oleoresin (18.90 %), ascorbic acid (122.66 mg/lOOg) and colour value (195.39 ASTA units). The check variety Vellayani Athulya was superior for characters such as days to first flower (23. 83 days), days to first harvest (42.96 days), fruit length (12.66 cm), fruit girth (6.27 cm), fruit weight (17.36 g) and flesh thickness (3.31 mm). No incidence of white fly, bacterial wilt, leaf curl, fruit rot and mosaic were observed in the field. The incidence of thrips and mites were less in the parents and hybrid combinations. The highest standard heterosis for green fruit yield plant'1 among the hybrids was recorded in P4 x P5 (177.23 %) followed by P3 x P5 (147.35 %), and P2 x P5 (127.24 %). For fruit weight highest standard heterosis was observed in P4 x P5 (191.09 %) followed by P3 x P5 (188.12 %) and P2 x P5 (170.30 %). Maximum standard heterosis for yield plot'1 was recorded in P4 x P5 (177.34 %), P3 x P5 (147.35 %) and P2 x P5 (127.31 %). Among the hybrids the highest standard heterosis for the quality characters such as oleoresin (36.59 %), ascorbic acid (6.05 %), and colour value (8.17 %) were recorded in P2 x P5. Correlation for different characters showed that green fruit yield plant"1 had positive correlation with the primary branches plant'1, fruits plant"1, fruit length, fruit weight, flesh thickness and seeds fruit'1. On the basis of the present study the hybrids CA 8 x CA 32 (P4 x P5), CA 6 x CA 32 (P3 x P5) and CA 5 x CA 32 (P2 x P5) were found promising for yield characters such as fruit weight, green fruit yield plant'1, yield plot'1 and quality. Among the parents CA 32 (P5) was found superior. The superior hybrids identified viz., CA 8 x CA 32 (P4 x P5), CA 6 x CA 32 (P3 x Ps) and CA 5 x CA 32 (P2 x Ps) can be subjected to multilocational trials and if found superior can be recommended for variety release. | en_US |
