The present study was carried out with ten tomato hybrids in polyhouse at experimental farm Department of Agriculture Guru Nanak college, Budhlada (Mansa) Punjab during Rabi 2020-21 to assess the genetic variability and character association analysis for Quantitative and qualitative traits in tomato (Solanum lycopersicum L.) hybrids for protected environment. The experiment was laid out in randomized block design with three replications. Data were recorded for fourteen Quantitative and qualitative characters. The experimental results revealed considerable differences among the genotypes for all the characters. Higher phenotypic and genotypic coefficients of variation (GCV, PCV) were observed for total number of fruits per plant, plant height, and total soluble solid. Moderate level of GCV and PCV was recorded for flowering days, number of locules per fruit, fruit yield per plant, number of fruit per cluster, number of flower per cluster, fruit diameter, number of cluster per plant, fruit length. High heritability together with high genetic advance as % of mean was observed in all the characters. Plant height, number of cluster per plant, pericarp thickness, total soluble solids, total number of fruit per plant, number of flower per cluster and number of fruits per cluster showed positive and significant connection with fruit yield /plant. Path coefficient analysis highest positive direct effects on fruit yield /plant was shown by total number of fruits per plant, plant height and number of locule per fruit, pericarp thickness, total soluble solid, fruit length could be reliable selection parameters for evolving high yielding genotypes

“…In the present investigation, the differential heterotic effects for these biochemical parameters of the hybrids might be due to the diverse genetic backgrounds of their parental lines. Similar heterotic effects for biochemical traits were earlier reported in many studies (Kumar et al, 2017;Panchbhaiya et al, 2020;Rameshkumar & Vethamonai, 2020).…”

The present study aimed to examine the performance of hybrids developed from advanced breeding lines in brinjal. Fifty F1 hybrids including three checks of different fruit groups were evaluated for yield and quality attributes in randomized block design with three replications. Analysis of variance indicated significant differences for different characters in small round, big round and long hybrids except fruit length among small round hybrids. Among small round hybrids, SR-5 × SR-9322 showed the highest heterosis for the number of fruits per plant (60.80%) and fruit yield per plant (6.17%) over the standard check PBH-3. Among big round hybrids, BR-15-2 × SR-9322, PC-123 × JG, BR-324 × SR-9322 and MR-494 × SR-6793 showed significant heterosis for a number of fruits per plant and fruit yield per plant in comparison to standard check PBHR-41. Among long hybrids, the hybrid combinations, BL-47 × MR-494, BL-47 × BR-21-6, BL-47 × MR-431, BL-47 × BR-1142 performed the best for fruit yield per plant overcheck hybrid PBH-5. For quality traits such as dry matter percentage, total phenols and anthocyanin, SR-5 × SR-9322 and MR-494 × SR-9322 (small round hybrids), BR-15-2 × SR-9322 and BR-1142 × SR-6793 (big round hybrids) and BL-214 × MR-319, BL-23 × MR-319 and MR-494 × BL-72 (long hybrids) performed better than their respective standard checks. The best-performing hybrids in the present investigation can further be exploited for commercial release

Heat resilient maize hybrids are an important input in maize cultivated area coupled with high temperature during the flowering period, with a specific focus on the Terai region of Nepal. The research was conducted in the Dhangadhi district from April 2020 to August 2020 in an alpha-lattice design with 26 genotypes and two replications. Analysis of variance suggests that genotypes were significantly different for all traits except plant height and plant population. The phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variation (GCV) for all traits. High PCV and GCV values were found in the anthesis silking interval, ear aspect and grain yield and low values in the anthesis days and silking days. Highly heritable traits were days to 50% tasseling (0.74), days to 50% silking (0.74), ear aspect (0.69), number of rows per cob (0.84), number of grains per row (0.61), cob diameter (0.87), and cob length (0.86). Genetic advance ranged from the lowest in plant height to the highest in anthesis silking interval. Correlation studies revealed that grain yield showed a negative and significant correlation with reproductive traits, while a positive and significant correlation between ear height and number of ears per hectare was observed. Cluster analysis grouped 26 genotypes into 5 major clusters, and the intracluster distance ranged from 4034.3 to 34960.3. Thus, traits having high variation can be used as selection indices for indirect selection for the improvement of maize productivity and suggest genotype like ZH182079, ZH1767, and KH15486 with high yield for commercialization and distribution to farmers.
