Evaluation of genetic diversity of parental lines for development of heterotic groups in hybrid rice (Oryza sativa L.)

Assessment of heterotic potential and combining ability of immortal restorer lines derived from an elite rice hybrid, KRH-2, for the development of superior rice hybrids

“…Negative correlation between DFF and PH, PT, NFGPP, TGW, YLD was observed in our study. These results are in accordance with [60] (for DFF and YLD), with [61] (for DFF and NPT), with [42] (for DFF and NFGPP, TGW) and is not in accordance with [2, 61] (for DFF and PH).…”

Population Structure of a Worldwide Collection of Tropical Japonica Rice Indicates Limited Geographic Differentiation and Shows Promising Genetic Variability Associated with New Plant Type

“…According to DeWoody et al [41], if the PIC value is more than 0.5, the marker will be considered highly informative, such as six markers identified in this panel, while the average PIC remained as high as 0.36. Several researchers observed similar results using SSR markers in rice [42][43][44], whereas much higher PIC values were also reported in some other studies [45][46][47].…”

Formation of Potential Heterotic Groups of Oat Using Variation at Microsatellite Loci

“…They suggested that the genetic distance between parents determined by molecular markers can be helpful in heterosis prediction for some traits, and categorization for heterotic groups and parental selection would be beneficial in cotton hybrid breeding. Similar statements were presented in sorghum and maize [7,42,43], rye [44], barley [45], wheat [46], rice [47], and in other crops. Wang et al [48] concluded that genomic selection predicted higher accuracy of genotypic value of genotypes for hybrid breeding but only if a higher number of field trials in more testing locations and years are used.…”
