Abstract

Character association and path analysis in fifty genetically diverse indigenous and exotic genotypes of chilli was studied for 16 important characters. The phenotypic and genotypic association of fruit yield was significantly positive with all the characters except days to first flowering and ten fruit weight. Early fruit yield and late fruit yield per plant were found highly significant and positive correlation with total fruit yield. The genotypic path co-efficient analysis revealed that ascorbic acid and chlorophyll content had high direct positive effect on total fruit yield.

Abstract

An investigation was carried out at College of Horticulture, University of Horticultural Sciences, Bagalkot during summer 2011 to analyze the variability and heritability in 67 cluster bean genotypes for vegetable pod yield and its growth and yield parameters. All the characters showed highly significant (at P=0.01) difference. Maximum range of variability was observed for ten fresh pod weight (g), number of branches at 90 DAS and number of dry pod per plant (dual purpose type). High heritability coupled with high genetic advance over mean was observed for number of branches at 90 DAS, pod length (cm), and ten fresh pod weight (g). The results of present investigation suggested that selection based on number of dry pod per plant, fresh pod weight, pod length and number of branches at 90 DAS might bring improvement in vegetable pod yield of cluster bean and its growth and yield components characters.

Abstract

Genetic variability, heritability, genetic advance and genetic advance as a per cent over mean for thirty two characters were assessed by field evaluation of fifty chilli accessions at College of Horticulture, Bagalkot (Karnataka) during 2010-11. High degree of variation was observed for all characters. The difference between phenotypic co-efficient of variation and genotypic co-efficient of variation were found to be narrow for most of the traits. The high estimates of heritability was found for plant spread (N-S) at 60 days (64.27%) and 120 day (65.47%) and (E-W) at 60 days (60.56%), number of fruits per plant at first picking (98.20%), early yield (94.67%), late yield (95.62%) and total yield (91.37%). The fruit characters like fruit width (96.22%), stalk length (81.04%) and ten fruit weight (96.44%), chlorophyll-a (95.45%), chlorophyll-b (97.52%), total chlorophyll (97.87%) and ascorbic acid (98.30%), fresh red chilli yield (95.18%) and dry red chilli yield (93.71%), hundred seed weight (70.67%) and number of seeds per fruit (94.67%) had also recorded high heritability.

Abstract

The present study was carried out with emphasis on ISSR profiling and genetic relationship studies on pearl millet using ISSR marker. The experimental material consisted of 15 genotypes of pearl millet. The seeds of 15 genotypes of pearl millet were grown in petriplates and the young leaves from them were used for DNA extraction. Extraction of total genomic DNA was carried out following the methods suggested by Saghai-Maroof et al. (1984) with minor modification. The selected primers generated 123 ISSR bands and the size of the amplification products ranged from 150-35000 bp. The number of bands generated per primer ranged from 09 (CA)₆RG to 19 (AC)₈YA with a mean of 13.6 bands per primer. Out of the bands generated 80 were polymorphic and 43 were monomorphic. The genotype GHB 235 showed maximum similarity (0.92) whereas, minimum was for ICMV 155 (0.55) among the genotypes studied.

Abstract

The present work investigated the biosynthesis of silver nanoparticles using Aspergillus flavus. The fungus, Aspergillus flavus when challenged with silver nitrate solution accumulated silver nanoparticles in 96 hr. The biosynthesized silver nanoparticles were confirmed by visual observation and UV-Vis spectroscopy. An absorption peak at 420 nm in UV-visible spectrum corresponds to the Surface Plasmon Resonance (SPR) of silver nanoparticles. The silver nanoparticles were found to be spherical and rod in shape. The X-ray diffractograms and SEM analysis indicate that the silver particles are crystalline in nature. From SEM images grain size of silver nanoparticles is ranging from 30 nm to 48.2 nm.

Abstract

Plant diseases have been concerned with mankind since agriculture began and played a crucial role in the destruction of natural resources and contributing 13 to 20 per cent losses in crop production worldwide (Anonymous., 1993). In particular, soil-borne pathogens cause important losses, fungi being the most aggressive. The distribution of several phytopathogenic fungi, such as Pythium, Phytophthora, Botrytis, Rhizoctonia and Fusarium have widely spreaded during the last few years due to change the introduced in farming with detrimental effects on crops of economic importance. In addition, not only growing crops but also stored fruits prey to fungalinfection (Chet et al., 1997). Moreover, an integrated approach promotes a degree of disease suppression similar to that achieved with full fungicidal treatment. For about 70 years, Trichoderma spp. have been known to attack other fungi, to produce antibiotics that affect other microbes and to act as biocontrol microbes (Weindling, 1934). Antagonists of phytopathogenic fungi have been used to control plant diseases and 90 per cent of such applications have been carried out with different strains of Trichoderma (Monte, 2001). The success of Trichoderma as biocontrol agents (BCAs) is due to their high reproductive capacity, ability to survive under very unfavorable conditions, efficiency in the utilization of nutrients, capacity to modify the rhizosphere, strong aggressiveness against phytopathogenic fungi and efficiency in promoting plant growth and defense mechanisms. These properties have made Trichoderma a ubiquitous genus present in any habitat and at high population density (Misra and Prasad, 2003).
