Between 1950 and 1970, the introduction of new sugarcane varieties and improved crop husbandry in the South African sugar industry contributed to substantial gains in sucrose yield. However, in the subsequent three decades to date, sucrose yield has remained approximately constant, despite an increased rate of variety releases. This lack of progress is a phenomenon common to many sugar industri...

Sequencing plant genomes are often challenging because of their complex architecture and high content of repetitive sequences. Sugarcane has one of the most complex genomes. It is highly polyploid, preserves intact homeologous chromosomes from its parental species and contains >55% repetitive sequences. Although bacterial artificial chromosome (BAC) libraries have emerged as an alternative for ...

The selection of sugarcane varieties is an important problem facing companies in Brazil that exploit sugarcane harvest for energy production. In the light of current concerns regarding the reduction of environmental damages and the efficiency of the production system, research into this problem is called for. In this context the authors begin by outlining the sugarcane variety selection in acco...

Traditional manual sugarcane harvesting requires the pre-harvest burning practice which should be gradually banned by 2021 for most of São Paulo State, Brazil, on cultivated sugarcane land (terrain slope ≤ 12%) according to State Law number 11241. To forward the end of this practice to 2014, a “Green Ethanol” Protocol was established in 2007. The present work aims at analyzing five years of con...

Sugarcane (Saccharum spp.) brown rust (caused by Puccinia melanocephala H. & P. Sydow) was first reported in the United States in 1978 and is still one of the great challenges for sugarcane production. A better understanding of sugarcane genotypic variation in response to brown rust will help optimize breeding and selection strategies for disease resistance. Brown rust ratings were scaled from ...

Formulations of Bacillus thuringiensis Berliner (Bt) with insecticidal activity against the sugarcane borer, Diatraea saccharalis Fabricius (Lepidoptera: Pyralidae), were developed and tested under laboratory and field conditions. The formulations were prepared using biodegradable polymers such as modified corn starch as an encapsulating agent, gelatin as an adherent, powdered sugarcane as a fe...

This investigation was performed to evaluate the biological efficiency (BE), mean mushroom weight (MMW), mean number of mushroom (MNM) and mushroom quality of Shiitake [Lentinula edodes (Berk.) Pegler] when grown on a sterilized substrate composed by sugarcane bagasse enriched with rice bran and sugarcane molasses. The proportions of rice bran were 0, 15, 20, 25 and 30% (dry weight/dry weight o...

GENETICALLY modified (GM) sugarcane, as with any other genetically modified organism (GMO), must be approved by regulatory authorities before it can be released in Australia. Growing GMOs is regulated by the Gene Technology Regulator under the Gene Technology Act 2000. The object of the Act is ‘to protect the health and safety of people, and to protect the environment, by identifying risks pose...

the occurrence of the hymenopterous parasitoid of the sugarcane whitefly, neomaskellia andropogonis corbett (hem.: aleyrodidae), in iran is newly reported. the aphelinid species, eretmocerus delhiensis mani, which was reared from nymphs of the sugarcane whitefly, belongs to the subfamily aphelininae and tribe eretmocerini.

42 Journal of Plant Registrations, Vol. 3, No. , January 2009 Based on its pedigree, HoCP 00-950 (Reg. No. CV-135, PI 654823) sugarcane (Saccharum spp.), is a complex hybrid whose genomic makeup consists largely of genes contributed by S. offi cinarum L. and S. spontaneum L., with minor input from S. barberi Jeswiet and S. sinense Roxb. amend. Jeswiet. Modern sugarcane cultivars such as HoCP 00...
