“…The maximum per se performance of parent was observed in Pondicherry 1 (5.30), while the hybrids had the range of 4.80 to 6.50 and maximum per se performance was observed in the cross Green long × Phule Shubhangi (6.50) followed by Pondicherry 1 × Punjab Naveen (6.35).. Green long × Phule Shubhangi (25.00 %) followed by Pondicherry 1 × Punjab Naveen (22.12 %) exhibited the significant standard heterosis over check Chitra. Similar results with significant heterosis for number of branches were reported by Shaik et al, (2011) and Sarkar et al, (2015).…”

An Indian origin cucumber (Cucumis sativus L.) is one of the most popular vegetables of the family Cucurbitaceae. It is the preferred in various ways, salad ingredient, pickles, deserts fruit and as a cooked vegetable, hence it has attained the crop improvement as compared to other cucurbit vegetables. Therefore the present investigation has been carried out to know the extent of heterosis for growth and yield parameters. The experimental materials consisted of 5 Lines and 5 Testers of cucumber collected from the germplasm maintained by the Department of Vegetable Science, College of Horticulture, UHS Campus, GKVK, and Bengaluru. Their 25 F 1 's were developed by crossing them in Line X Tester mating design. The IIHR-285, IIHR-341, IIHR-304, Green Long, Pondicherry-1, were used as lines and the Poinsette, Phule Shubhangi, Punjab Naveen, Pusa Uday, Kerala-1 were used as testers based on their yield potentiality. Observation from five competitive plants was recorded on various characters viz., vine length (cm), number of branches per vine, number of nodes per vine, Node of female flower appearance, node of male flower appearance, days to first fruit harvest, sex ratio, days to female flower anthesis and on fruit yield per plant (kg). Analysis of variance was carried out separately for all the characters. The present experiment identified the important hybrids for commercial use viz Green long × Poinsette, Green long × Pusa Uday, Pondicherry 1 × Punjab Naveen as which have exhibited the maximum significant standard heterosis for fruit yield per vine , for fruit length, average fruit weight, number of fruits per vine over the check Chitra.

“…However, hybrid Pusa Nasdar x Solani 5 (2.80) Pusa Nasdar x Kokan Harita (1.28), and NRG 9 x Solani 5 (1.95) showed significant sca effects for yield per plot and hybrid Pusa Nasdar x Solani 5 (59.16), Kokan Harita x Jaipur long (43.51), hybrid NRG 9 x Solani 5 (36.28) Arka Sumeet x Kokan Harita (26.87), Arka Sumeet x Jaipur long (28.80), and Kokan Harita x NRG 9 (20.69) for yield per hectare. Similar results were reported by Narasannavar et al (2014) [5] , Niyaria and Bhalala (2001) [6] , Mole et al (2001) [4] , Sarkar et al (2015) [7] , Lodam et al (2009) [3] and Tyagi et al (2010) [8] . The ratio of the component of general combining ability variance to components of specific combining ability was lower than unity, which indicated preponderance of nonadditive gene action for the all traits (Table 4).…”

Present investigation was carried out at All India Coordinated Research Project on Vegetable crops, Mahatma Phule Krishi Vidyapeeth Rahuri during kharif season of 2021.Six promising parental lines of diverse origin of ridge gourd selected, crossing them in half diallel fashion (without reciprocals). The performance of the parents and 15 F1s hybrids with one standard check was assessed in a randomized block design with three replications. Distance between rows was kept 150 cm and plants were spaced at 100 cm apart within row. Observations were recorded of 5 selected plants in each replication for the characters like average fruit weight (g), average length of fruit (cm), diameter of fruit (cm), yield per plot (kg) and yield per hectare. All agronomical practices were followed to grow good crop. The plant protection measures were adopted as and when required to control pest and diseases. GCA, SCA and gene action were calculated. From the estimates, it is observed that, the parent Pusa Nasdar (6.53), Solani 5 (10.05) showed highly significant positive gca effects for characters i.e. average fruit weight (g), average length of fruit (cm), diameter of fruit (cm), yield per plot (kg) and yield per hectare. Hybrid Pusa Nasdar x Solani 5 showed significant positive sca effects for yield per hectare and parents found better specific combining. Among the cross combinations hybrid Pusa Nasdar x Solani 5 was found promising for obtaining highest yields. From this study, it is showed that SCA variance is greater than GCA variance indicating the preponderance of non-additive gene action for yield characters, hence the character should be improved through heterosis breeding.

“…These crosses can be directly utilized for improvement of these char acter s thr ough the exploitation of heterosis or can be exploited for the development of better tr ansgressive segregants, since the parents Pusa Nutan, GARG-1, Jaipur Long and CO-1 involved in these crosses also exhibited high GCA. Similar r esults wer e r epor ted by Narasannavar et al (2014b), Niyaria and Bhalala (2001), Mole et al (2001), Sarkar et al (2015), Lodam et al (2009) and Tyagi et al (2010).…”

“…Among all the crosses it has been observed that ten crosses for node to first female flower appearance and nine crosses for days to flowering showed negative and significant heterosis over the better parent, similarly Kantharaj (2003) and Sarkar et al (2015) also reported the negative and significant heterosis for these characters. Only one cross each for fruit length, fruit girth and fruit weight showed significant positive heterosis over the better parent value.…”

Line × Tester analysis involving three lines and four testers was carried out in ridge gourd [Luffa acutangula (Roxb.) L.]. Significant variation was noticed in the mean performance of the parents and hybrids for all the characters studied except for vine length and fruit girth. The results from GCA and SCA variance indicated the predominance of non-additive gene action for all the traits except fruit girth. Significant heterosis of 177.78% over standard check, Arka Sumeet for fruit weight per plant was expressed by the cross GARG-1 × CO-1. The best general combiners were GARG-1 and Pusa Nutan among the lines, and Jaipur long and CO-1 among testers. Best specific combining ability effects for fruit length and yield (t/ ha) were recorded by the crosses Pusa Nasdar × Arka Sumeet and GARG-1 × CO-1.
