Originally published on Sustainnovate. The rapidly increasing competition in solar power auctions in India have promoted utilities to take advantage of the falling tariffs and procure electricity to meet their renewable purchase obligations. Delhi-based power utility BSES has announced plans to procure renewable energy power purchase agreements amounting to 700 MW through competitive auction.

Delhi power distributor BSES plans to procure 700MW of renewable electricity via a reverse auction that it claims will be the biggest private sector-led process of its type yet seen in India.

IN THE BSES-CSIRO sugarcane breeding program, breeders are using predicted breeding values to determine which clones are selected as parents, which crosses are made, and which families are entered into regional selection programs via progeny assessment trials (PATs). By doing so, we expect that parents with higher predicted breeding values will produce higher-performing families and a higher proportion of superior individual clones. In this paper we present results from three series of PATs to investigate the relationship between predicted breeding value of female and male parents, and their mid-parent value, and the performance of their progeny for cane yield (TCH) and sugar content (CCS). Mid-parent predicted breeding values were highly significantly associated with family performance for both TCH and CCS. Over the three series of PATs they explained about 19% of the family mean variation in TCH and about 23% in CCS. Single parent predicted breeding values explained about half of the variation that mid-parent predicted breeding values explained. No different association was found between female and male predicted parent breeding values. Source

RATOON STUNTING DISEASE (RSD), caused by the bacterium Leifsonia xyli subsp. xyli, has no specific external symptoms and internal symptoms are often unreliable. Immunoassays are widely used to diagnose the disease because they are sensitive, relatively inexpensive and are suitable for bulk screening. The most widely used immunoassays for RSD diagnosis are the enzyme-linked immunosorbent assay (ELISA) and the stalk tissue blot immunoassay. Phase-contrast microscopy is also used for diagnosis but one person can only process 100-200 samples in a day. These assay methods all use extracts from stalks of mature cane. Collecting stalks from mature crops of cane is heavy work and requires bulky stalk samples to be transported to the site where they are processed. RSD bacteria are known to occur in roots, stalks, leaf sheaths and leaves. Bacteria occur at low concentration in leaves. There have been two previous studies that have identified moderate to high levels of bacteria in leaf sheaths. Samples of leaf sheaths can be easily and quickly taken in the field and can be transported in small plastic bags. In this paper, we compare five different diagnostic methods for RSD; phase-contrast microscopy of extracts from stalks and leaf sheaths, ELISA on extracts from stalks and tissue blot immunoassay of stalks and leaf sheaths. Tissue blot of stalk tissue was the most sensitive method followed closely by ELISA. Tissue blot of leaf sheath tissue and phase-contrast microscopy had similar sensitivity but were less sensitive than tissue blot of stalk tissue and ELISA. The ELISA and tissue blot of leaf sheaths were compared for screening varieties for resistance to RSD. Twenty seven varieties were screened for resistance with both methods. The absorbance from the ELISA was highly correlated with the percent infected vascular bundles in the leaf sheath. This paper discusses the advantages and disadvantages of the various diagnostic assays. Source
