Abstract

Periyar Tiger Reserve is known for its rich fauna, particularly larger mammals. Grasses form an important food resource for the wild animals. During the studies on the flora of the Periyar Tiger Reserve, 163 species of grasses belonging to 74 genera were collected including seven species which have not been recorded earlier from Kerala. The species are listed in the alphabetical order. The nomenclature is made up to date. Important synonyms are also provided. Analysis with respect to endemism and rarity is also given.

Abstract

The biochemical changes during storage were studied in a set of fifty five spreading and semi spreading types of groundnut genotypes (Arachis hypogea L.). The studies indicated the effect of season and storage periods on these parameters. The genotypes behaved differently in different seasons and under different storage periods. Under storage both oil and protein showed marked reduction in their content. The variations were clearly observed in SDS PAGE analysis of protein and esterase isozymes. In the protein analysis 769 bands were observed in fresh Kharif 2010 seed whereas 696 bands were observed in stored summer 2010 seeds. The PIC (Polymorphism information content) of both summer and Kharif 2010 seed was found to be 0.94. Esterase analysis showed 181 bands in the fresh Kharif 2010 seed while, 101 bands were recorded in stored summer 2010 seed. The lower PIC value observed in Kharif and summer seasons for esterase isozymes as compared to proteins indicated that genotypic characterisation using the latter may be more reliable than former.

Abstract

Forty-five hybrids from 10 x 10 diallel of Gossypium arboreum L. genotypes were tested with their parents at Anand in kharif, 2006 for Heterobeltiosis and Standard heterosis. The heterobeltiosis for seed cotton yield ranged from -32.48 to 154.2 per cent and the value of standard heterosis ranged from -39.05 to 41.89 per cent. The hybrid CINA-343 x Jawahar Tapti (higher economic heterosis) and hybrids CINA-333 x CINA-344 and CINA-329 x DLSA-17 (high Heterobeltiosis) were the promising hybrids identified in this study for seed cotton yield per plant. The desirable heterosis was also observed in the cross combinations viz; CINA-344 x 824 for boll weight, number of sympodia per plant and number of bolls per plant; CINA-333 x CINA 344 for number of sympodia per plant and number of bolls per plant.
