Variability, heritability and genetic advance are basic in order to provide information for plant breeding programs. Forty nine upland rice genotypes were tested 7*7 simple lattice design at Fogera Wereta station of Adet Agricultural Research Center 2012/13. The objectives the study estimate variability, tested. Analysis variance revealed that there was highly significant difference among 49 al...

Eleven rice hybrids including two check varieties were evaluated to approximate their genetic variability, heritability and advance for ten quantitative traits. The analysis of variance illustrated that all the traits differed significantly indicating enough variation is presenting studied materials. Among desirable number filled spikelet’s per panicle was found have highest both phenotypic gen...

Grain yield in bread wheat (Triticum aestivum L.) is largely determined by inflorescence architecture. Zang734 an endemic Tibetan variety that exhibits a rare triple spikelet (TRS) phenotype with significantly increased spikelet/floret number per spike. However, the molecular basis underlying this specific spike morphology completely unknown. Through map-based cloning, causal genes for TRS trai...

QTL9 is a new potential quantitative trait locus related to rice panicle structure, identified through GWAS analysis of Vietnamese local panel. To validate the QTL9, biparental population was developed using low branching (G6) and high (G189) accessions from two haplotypes characterised by contrasting phenotype for secondary branch number spikelet traits. In parallel, Gene capture technology co...

Artificial selection of high yield crops and better livestock is paramount importance in breeding programs. Selection of elite parents with preferred traits from a phalanx of inbred lines is extremely laborious, time-consuming and highly random. General combining ability (GCA) was proposed and has been widely used for the evaluation of parents in hybrid breeding for more than half a century. Ho...

Rice panicle architecture is a key target of selection when breeding for yield and grain quality. However, panicle phenotypes are difficult to measure and susceptible to confounding during genetic mapping due to correlation with flowering and subpopulation structure. Here we quantify 49 panicle phenotypes in 242 tropical rice accessions with the imaging platform PANorama. Using flowering as a c...

Cytokinins (CTKs) regulate panicle size and mediate heat tolerance in crops. To investigate the effect of high temperature on panicle CTK expression and the role of such expression in panicle differentiation in rice, four rice varieties (Nagina22, N22; Huanghuazhan, HHZ; Liangyoupeijiu, LYPJ; and Shanyou63, SY63) were grown under normal conditions and subjected to three high temperature treatme...

Climate change increases the drought-affected areas, which challenge breeders to develop adaptive and drought-tolerant rice cultivars. The study aimed determine heritability, gene action controlling of various traits in upland F4 populations derived from cross, Sileso (high yielding drought tolerant) × Ciherang (early maturing), obtain high-yielding early-maturing lines. populations, along with...

The tassel seed mutations ts4 and Ts6 of maize cause irregular branching in its inflorescences, tassels, and ears, in addition to feminization of the tassel due to the failure to abort pistils. A comparison of the development of mutant and wild-type tassels and ears using scanning electron microscopy reveals that at least four reproductive meristem types can be identified in maize: the inflores...
