“…This suggests that the restorer line used carried two independent dominant fertility restoring genes, and one of the two genes had a duplicate effect that showed higher expression than the other gene and it alone could restore fertility. The findings are in line with those reported by Sattari et al (2008), Seesang et al (2014) and Hasan et al (2015) who found the duplicate dominant epistatic gene action at the fertility restoration inheritance of WA and Gambiaca CMS.…”

Development of hybrid rice depends on the effectivity of cytoplasmic male sterility (CMS) and restorer (R) lines. The molecular genetic approach is expected to help the breeder in identification of suitable parental lines to hybrid rice improvement. The study aimed to assess genetic relationship among three types of CMS systems (wild abbortive/WA Kalinga and Gambiaca) as female parents and to identify diversity of genes controlling fertility restoration in rice. The study used nine F 1 hybrids and F 2 populations obtained from the hybridization of three different CMS lines (IR58025A-WA, IR80156A-Kalinga and IR80154A-Gambiaca) with three restorer lines (PK90, PK12 and BP11). Fifteen SSR markers were used to select genomic regions of chromosome 1 and 10 on which Rf3 and Rf4 genes located in the hybrids. The results showed that fertility restoration in CMS-WA and CMS-Gambiaca was governed by two independent and dominant genes (Rf3 and Rf4), while in CMS-Kalinga the fertility restoration was controlled by one single dominant gene. Biological processes occurred in the fertility restoration of the hybrids were the same based on the pollen and spikelet fertilities of F 1 hybrids derived from three CMS and R lines, i.e. 76.1-78.3% and 69.1-76.6%, respectively. A restorer line PK12 had a higher capability in fertility restoration than PK90 and BP11. The SSR primers RM490 and RM258 were capable of identifying the Rf3 and Rf4 genes controlled fertility restoration in CMS-WA. The study supports the use of male sterile WA in rice hybridization.

“…Heterosis breeding is a principal genetic appliance that can facilitate yield enhancement by 30-40% and contributes to raising the desirable qualitative and quantitative traits in cultivated plants (Srivastava, 2000). Various degree of heterosis and heterobeltiosis on cultivars and elite lines of rice were observed by Nevame et al (2012); Sadimantara et al (2014); and Seesang et al (2014) for some agronomic and yield characters. The objectives of this study were to evaluate heterosis and heterobeltiosis of agronomic traits in Thai upland rice for identifying and selecting the favorable parental lines or cross combinations for developing high yielding upland rice varieties.…”

The exploitation of heterosis and heterobeltiosis are the promising way for raising yield potential in crops. Twenty-eight F1 hybrids and their eight parents were evaluated to estimate the heterosis and heterobeltiosis of yield and other agronomic traits in Thai upland rice. Significant differences of analysis of variance were observed for all studied traits, indicating the existence of worth genetic variability among the hybrids and their parents. The highest significant positive heterosis and heterobeltiosis was attained by Dawk Pa-yawm × Hawm Mali Doi for number of tillers (90.59%; 58.82%) and number of panicles plant-1 (60.35%; 46.14%), and panicle length (heterobeltiosis: 20.05%), but highest significant negative heterosis for plant height (-8.90%). Likewise, Nual Hawm × Khun Nan showed the highest significant positive heterosis and heterobeltiosis for yield components, viz., number of filled grains panicle-1 (57.39%; 52.25%), spikelet fertility (25.01%; 21.16%), 1000 grain weight (heterosis: 12.85%) and grain yield plant-1 (heterosis: 19.86%), but highest significant negative for days to flowering (-17.52%; -6.03%) and days to maturity (-12.00%; -4.91%). These crosses were recommended as the most promising combinations to gain early favorable segregants and developing high yielding upland rice hybrid varieties by heterosis breeding.

“…Based on fertility status, plants are classified into two groups, fertile and sterile. IR80151A was developed by IRRI and was used as female parent for three-line hybrid rice system in Thailand [36]. The results revealed that two dominant complementary genes with epistasis controlled the fertility-restorer gene of wild-abortive cytoplasmic male sterility system (WA-CMS).…”

Number of spikelets per panicle is one of the important characters for rice breeding programs to increase yield potential. The generation mean analysis based on six populations: viz., P1, P2, F 1 , F 2 , BC1, and BC2 of IR80151A/CH1 with utilizing cytoplasmic-genetic male, was performed. The results showed that dominant gene action was more important than additive type implying that selection in early segregating generations is ineffective and the character could be better exploited through heterosis breeding. Since hybrid rice was used the advantage of the dominant effect through heterosis, due to the role of more favorable dominant genes in F 1 hybrid than in both parents. In addition, utilizing cytoplasmic-genetic male sterility in the populations could specify gene control of fertility restoration in hybrid rice. The results revealed that two dominant complementary genes with epistasis controlled the fertility-restoration of wild-abortive cytoplasmic male sterility system (WA-CMS). This information will be useful for future rice breeding in three-line hybrid system.
