Fusicladium ahmadii on Pyrus pashia collected from Himachal Pradesh, India is illustrated and described in the present paper with special notes on its morphology and taxonomy. The description of fungus is given along with images of conidiogenous cells and conidia. As per literature consulted, this is the first report of Fusicladium ahmadii from India and probably second from world.

A population of was collected from the roots of Chinese juniper (Juniperus chinensis). The and morphometrical traits of the collected females were in agreement with these of describedin the original references, except for a few differences, such as the tail length and “c ” ratio. The sequences searching and alignment and phylogenetic analysis, which were based on the DNA sequence of D2-D3 expansion regions of 28S rDNA gene, further suggested that the species of this isolated nematode is. hunaniense. In China, it is the first time that X. hunaniense was intercepted from this new host imported from Tailand.

Keywords: Alien nematode – Xiphinema hunaniense– Chinese juniper– morphology– phylogenetic analysis

National Bureau of Plant Genetic Resources (NBPGR) New Delhi is the nodal agency for introduction of exotic germplasm including transgenics for research purpose in India. A range of transgenic crops have been developed across the world which are either herbicide-tolerant or insect resistant, or tolerant to drought/ stress or offering nutritional benefits, etc. India is also undertaking research in developing transgenics in different crops. During 2006-2013, a total of 4557 transgenic seed samples of various crops were introduced from different countries. Seed health testing of these samples for quarantine clearance resulted in the detection of eight pathogenic fungi viz., Alternaria padwickii in Oryza sativa; Bipolaris maydis in Zea mays; B. oryzae and B. sorokiniana in O. sativa; Fusarium verticillioides in Arabidopsis thaliana, Brassica spp., Gossypium hirsutum, Solanum esculentum, O. sativa and Z. mays; F. oxysporum f. sp. vasinfectum in G. hirsutum; Phoma sorghinain O. sativa and Arabidopsis thaliana; Rhizoctonia solani inO. sativa andZea mays. All the 740 samples found infected were salvaged before their release to the indentors.

Keywords: biosecurity–exotic pathogenic fungi – quarantine – seed health


5. First report of powdery mildew of Polyscias cumingiana caused by Pseudoidium sp. in India

Authors: Thite SV, Kore BA

Recieved: 05 September 2014, Accepted: 18 September 2014, Published: 30 November 2014

In January 2014, leaves of Polyscias cumingiana (=P. crispata)with typical symptoms of powdery mildew were collected in the Botanical garden of Yashavantrao Chavan Institute of Science, Satara (MS), India. Based on its morphological characters, the pathogen was identified as Pseudoidiumsp.(Erysiphe sp.). This is the first report of powdery mildew on P. cumingiana in India.

Keywords: Erysiphales – Erysiphe sp. – Araliaceae – Asia
