Correlation and Path Coefficient Analysis for Yield, Yield Attributing and Nutritional Traits in Rice (Oryza sativa L.)

Identification of Transgressive Segregants with High Zinc in Grains under Aerobic Condition in F4 Population of Rice (Oryza sativa L.)

“…Hence, these characters could be considered as criteria for selection for higher yield as they were mostly interrelated positively in addition to a positive association with grain zinc. This result was in conformity with the results of Rathod et al, (2017) and Ajmera et al, (2017).…”

“…The trait brown rice zinc (0.007) expressed direct effects on grain yield. This was in conformity with the findings of Ashlesha (2015) and Rathod et al, (2017). This indicated that grain zinc concentration does not have any role in enhancing grain yield per plant.…”

Iron biofortification in rice: in search of morphological traits for indirect selection in breeding programs

“…In this regard, some exceptions found here were for number of infertile grains per panicle and panicle weight, which associated with higher Fe content but at the same time usually in an opposite way to yield, thus, must not be considered in indirect selection. Given the importance of the approach but also the possible drawbacks applying indirect selection, similar work has been already carried out on rice in other countries (Anandan et al, 2011;Ajmera et al, 2017;Kalyan et al, 2017;Rathod et al, 2017;Sowmiya & Venkatesan, 2017). Differences in the results reported in these studies were found, which can be mainly attributed to the different germplasms assayed, but also environmental conditions.…”

Agronomic Characterization of Rice Genotypes and its Relations with Yield Trait

“…Negative genotypic correlations between grain yield per plant and panicle length [19] and harvest index [20] have also been observed. Significant positive genotypic correlation has been reported between yield per plant and plant height (0.21), panicles per plant (0.27), panicle length (0.53), effective grains per panicle (0.57) and harvest index (0.86), but significant negative correlation with 100 seed weight (-0.35) [9,17,[21][22][23][24]. Phenotypic correlations between seed yield/plant and other characters showed similar trend like genotypic correlations.…”

“…In comparison, mineral (iron and zinc) rich rice varieties such as Jaya ( 14), Palman 579 (16), HKR95-157 (17), and TNG67 (15) has relatively lower number of panicles/plant. Pusa Basmati 1 (21) and Japonica rice variety, Azucena (22) had the intermediate number of panicles/plant.…”
