Constructing and comparing selection indices for early growth traits in Saccharum spontaneum
نویسندگان
چکیده
Saccharum spontaneum is the major donor of important traits like vigour, hardiness and ratooning potential to modern sugarcane cultivars. Identifying S. clones with high early vigour tillering ability essential include them in hybridization program. Forty three accessions were evaluated for number tillers per clump, stalk length, diameter, leaves on main stem, leaf length lamina width at 90 days after planting. Variance components these indicated heritability coupled genetic advance indicating preponderance additive gene action traits. The comprehensive index Ci value, Smith-Hazel’s selection (SHI) rank sums all six viz., IND 99-848, 99-881, 99-849, 99-850, 99-984 99-847 superior can be utilised pre breeding programmes as donors identification bioenergy canes. Among methods studied, DTOPSIS was comparatively effective selecting genotypes. Keywords: Comprehensive index, spontaneum, Rank sums, Smith Hazel index.

A genetic linkage map of Saccharum spontaneum L. 'SES 208'.
The arbitrarily primed polymerase chain reaction was used to detect single-dose polymorphisms that, in turn, were used to generate a linkage map of a polyploid relative of cultivated sugarcane, Saccharum spontaneum 'SES 208' (2n = 64). The mapping population was composed of 88 progeny from a cross between SES 208 and a diploidized haploid derived from SES 208 by anther culture, ADP 85-0068. Thi...
متن کاملEconomically Relevant Traits and Selection Indices
IMPLICATIONS Sire selection should focus on that which is economical. This requires a true accounting of the traits that generate revenue or incur a cost within a specific beef cattle enterprise. Once the drivers of profit have been identified, sire selection should focus on the suite of traits that impact profitability. The use of bio-economic selection indices can dramatically reduce the comp...
متن کاملThe Evaluation of Growth Indices in Different Irrigation Systems and Weed Control Treatments and Correlation of Quantitative and Qualitative Traits of Sugarcane (Saccharum officinarum)
In order to evaluate the growth indices of sugarcane in different irrigation systems, weed control treatments and correlative associations with quantitative and qualitative traits of sugarcane, an experiment was conducted as split plot based on randomized complete block design (RCBD) with three replications in 2020 at Sugarcane Development Research and Training Institute of Khuzestan, Ahwaz, Ir...

Selection of high yielding genotypes is very important in sunflower. Thus, 24 new sunflower hybrids along with Golsa cultivar were evaluated in a simple lattice design (5×5) with two replications in the Agriculture Research Station of Gorgan, north of Iran, during 2020. The genotype by yield × trait (GYT) biplot method was used in order to study the relationships between different traits and to...
متن کاملThe reproductive biology of Saccharum spontaneum L.: implications for management of this invasive weed in Panama
Saccharum spontaneum L. is an invasive grass that has spread extensively in disturbed areas throughout the Panama Canal watershed (PCW), where it has created a fire hazard and inhibited reforestation efforts. Currently physical removal of aboveground biomass is the primary means of controlling this weed, which is largely ineffective and does little to inhibit spread of the species. Little is kn...
