“…Previously, Rebika (2017) also observed heterobeltiosis and standard heterosis for seed yield along with most of its yield components in pea which have the immense potential to exploit hybrid vigour or to isolate desirable segregants. Similar findings in pea have been reported by Nageshwar et al (2020), Katoch et al (2019), Halil et al (2019 and Kumari et al (2015).…”

“…Previously, Singh et al (2019) found significant estimates of both additive (D) and dominance (H) components for all pea characters except pod length. Similar findings in pea have been reported by Katoch et al (2019), Halil and Uzun (2019), Kumari et al (2015) and Cehyan et al (2008).…”

Background: A study was carried out to estimate the general and specific combining abilities, as well as heterosis for seed yield and yield associated traits in pea lines. Methods: Twenty-eight cross combinations were generated using half-diallel mating design with eight parental lines. The mean values of seed yield and its contributing traits of parental lines and their offspring for each replication were used for statistical analysis viz., GCA, SCA and Heterosis. Result: The GCA and SCA were significant and indicating the presence of both additive and non-additive types of gene actions. AP-3, VL-7, Kashi_Nandini and PC-531 were identified as promising parents due to significant GCA effects on seed yield and other traits. Among the crosses Kashi_Nandini x PC-531, VL-7 x PMR-53, Arkel x Vl-7 and VL-7 x Kashi_uday hybrids were the most promising, with significantly higher SCA effects for seed yield and yield related traits. Seed yield showed significantly high heterosis ranged from -2.00% to 8.77 % (AP-3 x PC-531 and Arkel x PMR-53, respectively) and relative heterosis ranged from -0.75% to 14.10% (Kashi_uday x PC-531 and Arkel x PMR-53 respectively) significantly exhibited positive heterosis for seed yield over better parent and mid-parent.

“…The experimental material consisted of 21 genotypes, including five parental lines (Line 12, Line 13, Line 14, Line 15 and Line 17), three testers (Matar Ageta{T1}, Palam Triloki {T2} and Arkel){T3} and their 15 crosses. The parents along with the hybrids were evaluated along with one standard check; Palam Triloki in randomized block design with three replications in 2014-15 (Katoch et al,2018) with row to row and plant to plant spacing of 45 cm ( in parents 30 cm) and 10 cm respectively. Each experimental plot was of 3m x 1.8 m size accommodating 6 rows.…”

In the present investigation, fifteen hybrids were developed during 2014-15 by utilizing five lines (Line 12, Line 13, Line 14, Line 15 and Line 17) and three testers (Matar Ageta, Palam Triloki and Arkel) and, were evaluated along with their parents for heterosis and combining ability studies following randomized complete block design during 2015-16. Same material was evaluatedin F2 during 2016-17 to ascertain the inbreeding depression. A wide range of residual heterosis over better parent and standard checks was observed in F2 generation for pod yield and related traits. Significant values of inbreeding depression and inbreeding vigour were found for almost all the traits in different crosses. Cross L13 x T2 exhibited maximum significant and negative residual heterosis over better parent (22.59%) and SC1 (17.39%) for days to 50% flowering and for days to first picking (9.50%), also exhibited maximum significant and negative residual heterosis (12.83%) over better parent for days to first picking. Studies on GCA effects revealed that line 17 was best general combiner for number of pods per plant, pod yield per plant and amongst testers, Palam Triloki for days to 50% flowering and days to first picking.On the basis of per se performance, extent of heterosis and specific combining ability effects, hybrid 17 x Palam Triloki and L13 × Palam Triloki were identified as the best crosses for earliness in F1 and F2 respectively. L17 x Arkel and L17 x Palam Triloki were observed as best hybrid for high green pod yield per plant, pods per plant and number of pods per plant in F1 and F2 respectively.

“…The hybrids' mean performance, heterosis, and potency ratio results showed a positive and substantial correlation between pod yield per plant and plant height, pod width, number of pods per plant, and pod weight, according to Galal et al (2019). However, the basis of heterosis estimated over superior parent and standard check (Palam Triloki) was explored by Katoch et al (2019). The hybrid (line 17 x Palam Triloki) displayed the highest significant and negative heterosis over the best parent for the characters, including the node at which the first flower opens, the days until 50% of the flowers have opened, and the days until the first picking, with heterotic responses of -26.09%, 5.62%, -5.66, respectively.…”

In tropical climes, the sensitivity of pea (Pisum sativum L.) to high temperatures as well as its underlying genotypic potential with regard to high-temperature ambient/tolerance at field scale remain unknown. The fraction of the hybrids' (F1) means values that increase or decrease relative to those of their best and middle parents is known as heterosis. "Heterobeltiosis" is the term used to describe how an F1 hybrid has improved over its superior parent. The selection of parental genotypes benefits from an understanding of general combining ability (GCA), specific combining ability (SCA), narrow-sense heritability (h2 n.s.), and broad-sense heritability (h2 b.s.). A significant improvement in salinity tolerance may be attainable through selection by the order of high heat stress tolerance values in the pea (Pisum sativum L.). The selection of parental genotypes benefits from an understanding of general combining ability (GCA), specific combining ability (SCA), narrow-sense heritability (h2 n.s.), and broad-sense heritability (h2 b.s.). The Pea (Pisum sativum L.) has high heritability values of the type that confer heat stress resistance, which suggests that a significant improvement in heat stress tolerance may be attainable by selection under conditions of intense selection pressure. Pisum sativum L. characteristics were mostly regulated by the additive and non-additive (dominance) gene activity under both normal conditions and heat stress.
