Avicennia marina (Tamil: Alai-atti): Avicennia marina is the dominant mangrove species inMuthupet and accounts for about 95% of the vegetation cover. Endophytic fungus is an endosymbiont which colonize healthy plant without causing any harm. These are relatively unexplored producers of metabolites useful to pharmaceutical industries (Petrini et al., 1992). Endophytic fungi are ubiquitous and have been found in all species of plant (Arnold et al., 2000
P 2412, a medium duration, high yielding medium slender rice culture was released as PY 6 (Subramania Bharathi) in January, 2000 for general cultivation in Pondicherry and Karaikal regions of the Union Territory of Pondicherry. It matures in 135 to 140 days. It has recorded a mean yield of 5852 kg ha in station trails and 5570 kg ha' in the adaptive research trials/on farm trails. Its overall mean yield in 74 locations (1993 to 1999) was 5534 kg har with 4 (ADT 38) to 19 per cent (Co 43/ I White Ponni) increased yield over checks. It is medium to tall in stature with compact panicle and medium size white boy grain. This variety is moderately resistant to blast and gall midge. PY 6 can be sown in September and is the best alternative to I White Ponni
A wide genetic diversity was revealed by the D² analysis wherein 41 genotypes of pearl millet Pennisetum typhoides (Burm.) S.&H.) fall into as many as fourteen clusters. Based on the average intercluster distances (D), the clusters XIII and XIV were found to be highly divergent from the other clusters. The types P.T.1595 and P.T.834/3 (Cluster XII) were superior for carnumber and grain yield. The types P.T. 928 and P.T. 834/1 (Cluster VIII) were superior for earliness while types P.T. 1611 and P.T. 1620 (Cluster VI) were superior for carlength and straw yield. These types may serve as potential parents for hybridisation programmes.
A new variety of paddy, PY.5 (Aravindar) has been released by the Government of Pondicherry from the Krishi Vigyan Kendra, Pondicherry for general cultivation. It was found to be a high yielder with good milling and cooking qualities. It recorded a mean grain yield of 6.3 tha with an increase of 12.5 and 43.4 per cent over IR.50 and TKM.9 respectively. It is semidwarf (90-95 cm) with long slender grain and matures in 100 to 105 days. It is moderately resistant to brown plant hopper and rice tungro virus with better storage potential.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
