“…Hence, it would be a promising cross that would yield early maturing segregants which would take us a way forward in developing super early lines of blackgram. Negative estimates of heterosis for days to maturity were also manifested in the reports of Kant and Srivastava (2012), Thamodharan et al (2016) and Suguna et al (2017).…”

Background: As blackgram cultivation is majorly spread in rain fed areas, breeding short duration and high yielding blackgram varieties is of profound importance to tackle terminal moisture stress and reap impressive yields by breaking the yield plateau. Hence, the present study was aimed to identify highly heterotic cross combinations for yield and earliness. Methods: Six parents along with 15 F1s were evaluated (rabi, 2019) for seed yield and its component traits along with earliness to estimate the magnitude of heterosis. Result: The cross LBG-752 × TBG-104 exhibited heterosis estimates in desirable direction for yield and earliness. The next best crosses were LBG-752 × PU-31, TU-40 × TBG-104, LBG-752 × TU-40 and IPU-2-43 × TBG-104. Because of its autogamous genetic architecture and biological constraints in large scale economic hybrid seed production, heterosis could be exploited only by isolating the early maturing and high yielding segregants followed by bi-parental or recurrent selection in early segregating generations and single plant selection in subsequent generations that would result in short duration and high yielding blackgram variety that fits well into different ecological niches.

“…The evidence of heterosis and heterobeltiosis enlightens the breeder about selection of perfect hybrid recombinants to work on particularly and also helps to differentiate between the parents and its hybrids better (Korkut, 1981) [10] . Correspondingly, (Jawaharlal et al, 2012; Thamodharan et al, 2016) [9,27] also concluded that the magnitude of heterosis provides information on extent of variation and genetic diversity of parents and has direct bearing on the breeding methodology to be adapted for varietal improvement program. The goal of this study is to conclude the appropriate crossbreeds by examining the hybrid progenies in terms of their heterosis over better parent or heterobeltiosis, economic heterosis or standard check and over mid parent for economic viable traits in Papaver somniferum L.…”

A line × tester analysis was conducted to assets the heterosis, heterobeltiosis and economic heterosis of sixty F1's by crossing 12 lines/females and 5 testers/males of diverse parents for fourteen viable economical traits in Papaver somniferum L. The analysis of variance concluded that parents vs hybrids contrast were recorded only 50% significant for the characters and rest non-significant for the traits like days to flowering (50%), no. of leaves/plant, pedicel length, no. of capsule/plant, Seed yield, dry husk capsule and codeine alkaloid content (%) indicated, existence of plentiful variability among parents and crosses for all the characters studied. The investigational result revealed that hybrids L10×T2, L10×T5, L12×T3 and L12×T4 exhibited the best heterosis over better as well as economic parent both for more than one traits, namely-no. of capsule, capsule index, seed yield (g/plant), dry husk yield (g/plant), morphine, codeine, thebaine, papervine and nosacapine alkaloid content (%) in desirable direction. Therefore, these promising crosses can be recommended for exploitation of heterosis to obtain appropriate segregants for crop improvement program in opium poppy.

“…The determination of heterosis and heterobeltiosis informs the breeder about which hybrid combination to choose and work on particularly and helps the breeder see the difference between the parent and its hybrids better (Korkut, 1981). The magnitude of heterosis provides information on extent of genetic diversity of parents and has direct bearing on the breeding methodology to be adapted for varietal improvement (Jawaharlal et al, 2012;Thamodharan et al, 2016). The aim of this study is to determine the appropriate crossbreeds by examining the hybrid progenies in terms of their heterosis over mid parent, better parent or heterobeltiosis and standart check levels in alkaloid ratios.…”

This study aimed to determine suitable opium poppy hybrids over mid parent, better parent and standart check levels in alkaloid ratios. In the study, 36 hybrids were evaluated derived from nine varieties. The experiment was carried out in four replications in randomized block design in 2016 and 2017. Heterosis over mid parent values ranged from -4.91% to 65.43% for morphine, -76.91% to 278.05% for thebaine, -68.97% to 180.91% for noscapine, -53.60% to 150.45% for codeine, -93.55% to 289.61% for oripavine and -78.69% to 285.94% for papaverine. In the result study of 34 crosses recorded positive heterosis over mid parent for morphine content followed by 24 for thebaine, 23 for noscapine, 26 for codeine, 22 for oripavine and 15 for papaverine.
