“…For the traits days to 50 % flowering, plant height and days to maturity, out of three female lines, one line ICMA 93333 was considered as a good general combiner and three testers viz., BIB 193, BIB 186 and BIB 281 were good general combiner for days to maturity and days to 50% flowering but for PH BIB 180, BIB 212 and BIB 241 showed significant positive gca effect (Table 3). These results were comparable with the findings of Kumar et al (2017) and Krishnan et al (2017) who 212 for ear head diameter (Patel et al,2018) and BIB 241 and BIB 283 for seed yield per plant (Kumar et al, 2017) showed positive significant gca effects and hence, can be used as a good combiner (Table 3). to flowering (Sushir et al, 2005;Kumar et al,2017), five crosses for days to maturity (Sushir et al, 2005;Bhanderi et al, 2007), one (Kanfany et al, 2018) and three crosses (Rathore et al,2004;Kumar et al, 2017) for plant height with negative and positive sca effect, respectively, three (Kanfany et al, 2018) and three crosses (Rathore et al, 2004;Kumar et al, 2017 andKanfany et al, 2018) for the number of tillers with negative and positive sca effect, respectively, one cross for ear head length (Krishnan et al, 2017), four crosses for test weight (Kumar et al, 2017 andKrishnan et al, 2017) and harvest index (Kumar et al, 2017), seven crosses for biological yield (Krishnan et al, 2017) and nine crosses for seed yield (Sushir et al, 2005;Kumar et al, 2017;Kanfany et al, 2018).…”

“…Therefore, in the present study, standard heterosis was estimated for various characters over best check hybrid HHB 67 (Table 5). In the present study, a significant heterosis effect in the desirable direction (positive for all the traits except Days to 50 % flowering, days to maturity and plant height) was reported such as eleven crosses for days to 50 % flowering (Sheoran and Govila,1996;Karad andHarer, 2005 andYadav,2006) and nine crosses (Rathore et al, 2004;Kumar et al, 2017) for plant height (Kanfany et al, 2018), three (Kanfany et al,2018) and three crosses for the number of tillers (Chittora and Patel, 2017) and Bhasker et al,2017), one cross for ear head length (Krishnan et al, 2017), one cross for ear head length (Salagarkar et al,2016 andBhasker et al,2017) and harvest index (Singh et al,2015); Nandaniya et al,2016) and Chittora and Patel (2017), three crosses for biological yield (Singh et al,2015 andKanfany et al, 2018) and seed yield (Chittora and Patel, 2017;Bhasker et al, 2017;Kanfany et al, 2018).…”

The present study was conducted to estimate the combining ability and heterosis in pearl millet hybrids. Forty five pearl millet hybrids were developed using three male sterile lines (A line) with fifteen restore lines (R line) through the Line x Tester mating approach and were evaluated during kharif, 2018. Analysis of variance revealed that the mean square of treatments showed significance for all the traits. For days to 50 % flowering and days to maturity, lines viz., ICMA 93333, ICMA 97111, BIB 186, BIB 193 and BIB 281 had negative gca effect so these lines can be used as parents for hybrid development under harsh environmental conditions. Based on sca effect, heterosis and per se performance, crosses ICMA 97111 x BIB 208, ICMA 93333 x BIB 186 and ICMA 88004 x BIB 283 were identified as potential crosses for commercial exploitation of heterosis in pearl millet.

“…Among 49 hybrids, fourteen hybrids displayed notable positive specific combining ability impacts on grain yield per plant. Previous significant GCA and SCA impacts in pearl millet for grain yield and component characteristics were also documented by Reshma Krishnan et al (2017) [20] , Davda and Dangaria (2018) [8] , Sharma et al (2019) [23] , and Patel (2022) [18] . In reference to heterosis over mid parent, superior parent, and standard heterosis, a substantial level of heterosis was observed in the desired direction across all traits.…”

Pearl millet, also known as Pennisetum glaucum L. R. Br., is regarded as a resilient Nutri-cereal that serves as the primary food staple for a large population within the country. A study was carried out to improve its grain mineral composition through the utilization of line × tester analysis, aiming to ascertain the levels of heterosis, gene action, and combining ability concerning grain yield potential, as well as the presence of grain mineral elements such as iron (Fe) and zinc (Zn). Seven CMS lines, in addition to 7 restorers (testers) of pearl millet, were employed for the current investigation. For ten agronomic and two micronutrient characters at 3 locations of the S.D.A.U.; during kharif 2021. All the genotypes were evaluated in RBD replicated thrice in three environments formed by different locations. In the case of most characteristics, notable discrepancies arose due to environmental factors, parental influences, and hybrid combinations, highlighting the considerable variability within the materials. Examination of genetic mechanisms revealed a predominance of non-additive and additive gene effects across different traits. The CMS lines SDMA 1 and pollen parents 15725 R and 16088 R had good general combiners for grain yield per plant and majority of its attributes. The hybrids ICMA 98444 x 16088 R (with an average x good rating), SDMA 1 x 15725 R (good x good), and ICMA 05888 x 15725 R (average x good) were derived from parental lines that exhibited high per se performance. These hybrids showed significant positive Relative heterosis, heterobeltiosis, and standard heterosis, along with a positive specific combining ability effect for both grain yield per plant and component characters.

“…The variability due to specific combining ability (σ 2 sca ) was five to six times more than variability due to general combining ability (σ 2 gca ) for grain yield and 1000 seed weight and predictability ratio less than 0.5. Earlier studies of Lakshmana et al (2010), Reshma Krishnan et al (2017) and Warrier et al (2019) also reported similar influence of non‐additive gene action for grain yield and 1000 seed weight. The promising combiners identified for rancidity and other characters under study are presented in Table 9a.…”

Combining ability for rancidity and associated traits in pearl millet (Pennisetum glaucum)

et al. 2023

Pearl millet occupies an important place in attaining nutritional security in marginal areas; however, as it develops off‐flavours, it is less preferred by food industry. The objective of the current study was to determine the variations in rancidity‐related traits and estimate the combining ability of inbreds and hybrids for these traits under varied environmental conditions. In this study, 32 hybrids were developed from eight lines and four testers using line × tester mating design and evaluated along with parents and checks 86M86 and HHB 67 for yield and rancidity‐associated traits in three environments. The hybrids L7T2 and L6T1 are identified as promising hybrids for grain yield and rancidity. Higher variance due to specific combining ability and predictability ratio for grain yield and rancidity‐associated characters indicate the predominance of non‐additive gene action. The tester T1 recorded a significant negative GCA effect with low alcoholic acidity. A significant and positive SCA for grain yield was observed in L3T1 and L7T2, whereas for rancidity in L5T4. Alcoholic acidity showed a significant positive association with 1000 seed weight, lipase and lipoxygenase in parents and negative association with 1000 seed weight in hybrids.
