“…The combined analysis of variance (ANOVA) showed that mean squares from genotype and environment obtained for pod yield per plant and other studied component traits were significant, except for kernel length/width ratio, indicating significant variation present among the genotypes under study, which offers great scope for improvement of traits through breeding line selection. Similar results have also been reported by earlier workers as well [ 30 – 33 ], for pod yield and its related characters. G×E interactions were significant for pod yield, days to flower bud initiation, days to 50% flowering, hundred pod weight, and kernel weight ( Table 3 ), suggesting that genotypes respond differently from season to season, which is in agreement with the results of earlier studies [ 34 ].…”

India imports the most edible oils because domestic demand exceeds production. Horizontally expanding groundnut production in non-traditional areas especially in the potato-paddy rice-fallow system is possible for increasing production and it requires trait-specific cultivars. Only 1% of oilseeds are grown in non-traditional regions. Nine interspecific groundnut derivatives were tested in potato-fallow system at Deesa, Gujarat, and Mohanpura, West Bengal, and non-potato fallow areas in Junagadh during Kharif 2020 to examine their performance and adaptability. Genotype-by-environment (G×E) interaction significantly affected pod yield and its components in the combined ANOVA. "Mean vs. stability" showed that the interspecific derivative NRCGCS 446 and variety TAG 24 were the most stable and valuable genotypes. GG 7 yielded more pods in Junagadh, whereas NRCGCS 254 yielded more in Mohanpur. Low heritability estimates and strong G×E interaction for flowering days showed complicated inheritance and environmental effects. The shelling percentage was significantly correlated with days to 50% blooming, days to maturity, SCMR, HPW, and KLWR, demonstrating negative connections between maturity, component characteristics, and seed size realisation.

“…Variations in reciprocal crosses imply maternal influence on biomass, grain yield, and harvest index (Kivrak et al, 2020). Maternal influence has also been reported in the yield and harvest index in sorghum (Mengistu et al, 2020;Shinda et al, 2021), and in legumes (Ofori & Padi, 2020;Kamdar et al, 2020). Thus, to improve yield in chickpea using hybridization choice of parents is critical.…”

“…Differences between crosses and their reciprocal for yield improvement have been reported (Yasar et al, 2014) in chickpeas. Other reports are in groundnuts, sorghum, pearl millet (Kamdar et al, 2020;Daudi et al, 2021;Shinda et al, 2021;Patil et al, 2021b). This indicates the existence of maternal influence in C. arietinum hybrids.…”

Chickpea is a major source of proteins especially in arid and semi-arid areas of Kenya. However, its average yield per hectare is low when compared to neighbouring countries. This research was carried out to determine the levels of hybrid vigour on yield in the F1 generation. To obtain the F1s, reciprocal crossing between Mwanza 2 and Chaina I was carried out with controls being the parental lines. The experimental layout was a randomized block design replicated thrice for three seasons. A spacing of 50x20cm was used in plants, while all other agronomic practices were maintained constant. Data on grain yield and biomass per plant was obtained by measuring the weight, then subjecting it to a one-way ANOVA in SAS 9.4 software. Mwanza 2 expressed the highest biomass (2.56g), while both parents attained a maximum grain yield of 1.69g per plant. Chaina I x Mwanza 2 hybrid expressed maximum means of F1s for biomass (2.31g) and grain yield (1.4g) per plant. Chaina I x Mwanza 2 hybrid recorded the highest biomass and grain yield in better parent heterosis with 14.36% and 330% respectively. Mid-parent heterosis means were also highest at 24.53% and 405.88% for biomass and grain yield respectively. Further, the heritability was maximum for biomass under Mwanza 2 x Chaina I, varying from 93.1% to 100%, while Chaina I x Mwanza 2, expressed maximum grain yield and harvest index. Better parent heterosis and mid-parent heterosis was highest in Chaina I x Mwanza 2 than its reciprocal, Mwanza 2 x Chaina I.

Groundnut breeding is focused on developing high-yielding Spanish–type varieties with fresh seed dormancy (to avoid sprouting). Fourteen advanced breeding lines were multi-phenotyped and genotyped for fresh seed dormancy under different germination tests. Further, the genotypes were evaluated for their performance and adaptability using GGE biplots. Thus, widely adapted genotypes were PBS 11077 and PBS 15014 for pod yield per plant (PYLP); PBS 14064 for sound mature kernels (SMKs); PBS 16023 for hundred pod weight (HPW); and PBS 11077 for hundred kernel weight (HKW). PBS 14064 and PBS 15056 (for PYLP), PBS 15056 and PBS 15022 (for SMKs), PBS 16022, PBS 16044 and PBS 14060 (for HPW) and PBS 14064, PBS 14060 and PBS 14068 (for HKW) were appropriate for a specific environment. So, the fresh dormant genotypes PBS 11077, PBS 16023, PBS 14064 and PBS 15014 performed well across all test locations and were designated as ideal in terms of fresh seed dormancy, yield, stability, and emerged as the top fresh dormant genotypes
