Hayman analysis for lint percentage, boll weight, fibre quality and bacterial blight resistance of a ten-parent half-diallel set of crosses was conducted in Upland cotton . The ten parents represented a fixed sample of the best germplasm available to Australian breeders for the characters of commercial importance . Heterosis and inbreeding depression were detected, particularly for boll weight and blight resistance . An analysis of genetic components and parameters indicated that since additive effects were substantial and heritability high, early-generation selection of spaced plants and pure-line breeding should be successful . Some genotypes were identified as being potentially good donors for hybridization since they possessed dominant genes for improved character expression . Acala C-1 was identified as the first-choice parent for increased boll size, Coker 315 for increased span length, while Namcala was the best parent for breeding improved fibre strength . McNair 220 possessed the most dominant genes for high lint percentage . Reba P279 and Siokra were the only parents with resistance to the prevelant race of bacterial blight .

“…Loden and Richmond (1951) reviewed cross-pollination data in cotton available in the literature until 1950 and found a large variability from 1 to 81%, compromising the purity of breeding stocks and varieties. This variability was also detected in the 60s in the Mississippi Valley (USA), with rates between 10 and 47% (Simpson, 1954;Simpson and Duncan, 1956;Sappenfield, 1963).…”

“…As early as 1894, it was reported that hybrids between Gossypium hirsutum L. and Gossypium barbadense L. exhibited great heterosis in vegetative growth [19]. Subsequently, several attempts were made to apply similar principles in intraspeci c cottons [20,21]. Previous studies have shown that heterosis in cotton may be correlated with vegetative heterosis at the seedling and squaring stages [22].…”

Background Heterosis has been exploited for decades in different crops for the dramatic increase in yield but less documented molecular evidences reported in cotton. Results An elite cotton hybrid variety ‘Huaza Mian H318’ (H318) and its parental lines was used to explore the source of its yield heterosis. A four years’ investigation of yield related traits showed that the boll number of the H318 was stable higher compare with its two parents whether in the climate suitable or unsuitable years. Besides, the hybrid H318 grows faster and showed higher fresh and dry weight than its parental lines at the seedling stage. Transcriptome analysis of seedlings identified 17,308 differential expressed genes (DEGs) between H318 and its parental lines, and 945 extremely changed DEGs were screened out for later analysis. In which, most DEGs (931/945) were gathered between H318 and its paternal line (4–5), but only 78 DEGs were found between H318 and its maternal line (B0011), which implied that H318 display more similar gene action with its maternal parent. GO and KEGG analysis showed that these DEGs highly enriched in photosynthesis and carbohydrate metabolic processes, the expression level of these DEGs was significantly higher in the H318 relative to its parental lines, which implies that sucrose and starch biosynthesis were enhanced in H318. Conclusion The enhanced photosynthesis and carbohydrate metabolic capability contributes to the heterosis of H318 at seedling stage, and establish the material foundation for later higher boll setting rates in the complex field environments.
