Comparative Performance of Lowland Hybrids and Inbred Rice Varieties in Nigeria

Genetic Variability and Correlation Coefficients of Major Traits in Cold Tolerance Rice (Oriza sativa L.) Under Mountain Environment of Nepal

“…Selvaraj et al (2011) reported very similar result as our findings. Akinwale et al (2011) reported high heritability for Yld, DH, DM, Pht, NGPP similar to our finding but low for TGW and NPPH in contradiction. Similarly, Ogunbayo et al (2014) reported similar result for all traits but medium heritability for grain yield (44.6).…”

“…Tiwari et al (2019) also reported high GA and high heritability for yield and low GA and high heritability for DH and DM this is similar to our findings. Akinwale et al (2011) reported similar findings high heritability coupled with high GA for NGPP, Yld and NPPH. Selvaraj et al (2011) reported similar result as our findings for Yld, NGPP, NPPH but in contradiction he reported high GA for DH and DM at 1% level of selection intensity.…”

Heritability and path coefficient analysis for important characters of yield component related to grain yield in M4 red rice mutant

“…Those means indicate that all of the observed charactersare greater controlled by genetic factors than environmental factors and the selection made of these characters can be achieved through the phenotypic of those characters. This is in line with the opinion of Akinwale et al [7], Naseem et al [10] and Konate et al [8] that characters with high heritability values are more controlled by genetic factors and those characters can be used as selection criteria for selecting superior lines based on the phenotypic characters. The result of path analysis is presented in Table 3, showed that the number of productive tillers per hill, the number of grains per panicle, and the grain weight per hill werethe characters that havesignificant positive direct effects on the grain yield per hectare with the values of direct effects (C) were 0.729*, 0.916*, and 0.637* respectively, whereas the panicle density was a character that has a non signicant negative direct effect on the grain yield per hectare with the value of direct effect -0.497 tn on the grain yield per hectare.…”

“…The coefficient variation of phenotypic values (PCV) obtained for all characters ranged from 21.02% to 54.86%, whereas the coefficient variation of genotypic values (GCV) for all characters ranged from 16.50% to 51.50%. According to Akinwale et al [7], Konate et al [8] and Sumanth et al [9], the values of the phenotypic coefficient variation (PCV) and the genotypic coefficient variation (GCV) greater than 20% are categorized as high and those characters can be used as selection criteria in the improvement of mutant lines. ns= not significant; *= significant at 5% level; **= significant at 1% level…”

Physical, functional, pasting and thermal properties of flours and starches of six Nigerian rice cultivars

“…In sub-Saharan Africa, over 20 million farmers grow and produce about 4.8 million tonnes of rice (FAOSTAT, 2014). The demand for rice in sub-Saharan Africa is expected to grow substantially as the population is currently growing at the rate of 3e4% per annum and rice consumption is growing faster than other foods (Akinwale et al, 2011). About 20 species of the genus Oryza are recognized, but nearly all cultivated rice is Oryza sativa L. A small amount of Oryza glaberrima, a perennial species is grown in Africa (Falade, Semon, Fadairo, Oladunjoye, & Orou, 2014;Yadav & Jindal, 2008;).…”
