Study of combining ability and heterosis were conducted on 12 F1 hybrids along with seven rice genotypes (three cytoplasmic male sterile lines and four restorer varieties) to know the pattern of inheritance of some morphological traits for selecting superior genotypes. The experiment was carried out according to line x tester mating design, in Sari Agricultural Sciences and Natural Resources Un...

general and specific combining ability of some rice lines and cultivars with irri sources were determined using the line × tester procedure (5 pure lines were crossed with 4 local cultivars as tester). parents and their progenies were planted in a randomized complete block design with three replications in the research field of iran rice research institute. traits such as yield and its componen...
متن کاملLine x tester analysis in sugarcane (Saccharum officinarum)
Combining ability variances and effects were estimated for important agronomic and biochemical traits in sugarcane using line x tester mating design. Five commercially grown varieties and one line from germplasm collection were involved in this study of which three were used as females (lines) and three as males (testers). The six agronomic characters studied were number of millable stalk per s...
متن کاملGenome-Wide Transcriptome Profiles of Rice Hybrids and Their Parents
Heterosis is a widely studied phenomenon in several plant species. However, its genetic basis still remains to be elucidated. In this study, we used RNA-seq data from two rice genotypes and their reciprocal hybrids, and used a combination of transcriptome profiling and allele-specific expression analysis to identify genes that are differentially expressed in the hybrids and their parents or exp...
