Twelve genotypes with variation in seed size, seed weight, seed coat colour and seed shape were included for the study. Genotype RVSSG-44 recorded maximum percent loss in seed weight. Genotype RVSSG-43 had minimum percentage of seed infestation, which was significantly less than rest of the genotypes, except JG-130 seed infestation. Susceptibility index of pulse beetle on different genotypes of chickpea showed that there were no significant differences among different genotypes. Infestation percentage positively and significantly associated with protein content in fresh seed and infested seed. However, other parameters were not associated with infestation by beetle. It ranged from 11.7 to 13.0 adult on angular and pea shape seeded genotypes, respectively. Seed size and seed shape of the genotypes did not influence the fecundity, adult emergence, total development period and susceptibility index of pulse beetle.

The experiment was conducted to find out the efficacy of dodder vine extract as seed protectant against pulse beetle, Callosobruchus chinensis on gram seed in the laboratory of the Department of Entomology, Bangladesh Agricultural University, Mymensingh during the period of February to May, 2009. The concentrations of dodder vine extract were 5, 2 and 1% respectively. Efficacies of these treatments were evaluated by considering oviposition, adult emergence, intensity of damage and seed weight loss done by pulse beetle. Dodder vine extract was found effective in checking oviposition, adult progeny development and severity of seed damage. Seeds treated with 5% concentration of dodder vine extract were less preferred for oviposition, adult emergence and seed weight loss by C. chinensis and this conc. might be useful in protection of pulse seed.

The pesticidal efficacy of four locally available leaves of botanicals like neem (Azadirachta indica), datura (Datura stramonium),  marigold (Tagetes erecta) and garlic (Allium sativum L.) tablet powders was assessed on pulse bettle (Callosobruchus chinensis L) through adult mortality and emergence, oviposition performance, seed damage, weight loss and germination  of chickpea (Cicer arietinum). The above test biopesticides were tested at three different rates (0.5 g, 1.0 g and 1.50 g powder/kg of chickpea seeds). All the tested powder showed significant effect on the above parameters. The highest adult mortality was recorded when chickpea seeds were treated with datura leaf powder at 1.50 g/kg, whereas marigold showed the least effect on adult mortality. The powders used in the experiment effectively controlled oviposition and adult emergence of pulse beetle. The lowest number of adult emergence was obtained from chickpea seeds treated with datura leaf powder at 1.50 g/kg. The highest weight loss was observed in control seeds followed by marigold leaf powder 0.5 g/kg gram seeds. Datura leaf powder treated seeds showed the lowest seed weight loss followed by neem, garlic and marigold. Plant powders had profound effect on seed germination. The highest germination was observed in treated seed with datura leaf powder at 1.50 g/kg and the lowest germination in control seed followed by marigold leaf powder at 1.5 g/kg treated seeds. The pesticidal effect on oviposition, adult mortality, adult emergence, and seed weight loss was directly proportional to leaf powder rates.

Seed size is an important trait in common bean. The objective was to identify RAPD markers associated with QTL for seed weight, seed length, and seed height in a molecular marker-based linkage map in a recombinant inbred (RI) population from the common bean cross of the larger seeded (100 seed/39 to 47 g) PC-50 (ovate seed shape) × smaller seeded (100 seed/26 to 35 g) XAN-159 (flat rhomboidal seed shape). The parents and RI lines were grown in two separate greenhouse and two field (Wisconsin, Dominican Republic) experiments using a RCBD. Continuous distributions for seed weight, seed length, and seed height were observed for RI lines indicating quantitative inheritance. One to three QTLs affecting seed weight explained 17% to 41% of the phenotypic variation. Two to three QTLs for seed length explained 23% to 45% of the phenotypic variation. One to four QTL associated with seed height explained 17% to 39% of the phenotypic variation. A RAPD marker M5.850 in linkage group 3 was consistently associated with seed weight, seed length, and seed height in all experiments and explained 7% to 13% of the phenotypic variation for these traits. A seedcoat pattern morphological marker (C) in linkage group 1 was associated with seed weight and seed height in two greenhouse experiments.

AbstractThe variation for protein content has been assessed in a series of pea (Pisum sativum L.) lines differing in mean seed size. The range of seed size within each genotype was manipulated by growing the plants in different environments and by altering the structure of the plant. The response of the lines in terms of seed weight to the environments and treatments was inconsistent, but 90% of the total variation was accounted for by differences between genotypes. In contrast, for percentage protein, the genetic component was much weaker with nearly half the variation being accounted for by within (residual) variation. The correlations between seed weight and percentage protein were highly genotype specific. For the largerseeded genotype, percentage protein increased with increasing seed size (r= +0.9, P < 0.01), while for the small-seeded genotype there was mid-range negative value (r = −0.5, P <0.01). It is suggested that any assessment of percentage protein in pea genotypes must take account of seed size.

Experiments were carried out in the laboratory to assess the effectiveness of Nogos, Malathion, Sevin and Limper on lentil, gram, grasspea, greengram and blackgram seeds with eggs of pulse beetle, Callosobruchus chinensis L. Insecticides were sprayed on the seeds along with eggs and found that all the tested insecticides inhibited hatching of eggs resulting in significantly lowest rate of adult emergence. Nogos and Malathion recorded the lower number of emergent adults. The overall 26.35- 100% reduction of seed damage and 40-100% weight losses were achieved in insecticides treated seeds of five different types of pulses showing highest reduction in seed damage and weight losses due to Nogos and Malathion treatments. The treatment of the pulse seeds with the insecticides did not affect the seed germination. Key words: Insecticides, pulse beetle, egg treatment, pulses, seed damage.

A total of 51 accessions of different Lens spp. viz., Lens culinaris (cultivated) and L. culinaris subsp. odemensis, L. culinaris subsp. orientalis, L. orientalis, L. nigricans, L. lamottei and L. ervoides (wild species) were screened for their reaction to Callosobruchus chinensis under no-choice artificial infestation conditions to find the sources of resistance. Significant differences among the accessions in terms of number of eggs laid, development period, adult emergence, number of emergence holes of C. chinensis loss in seed weight on different Lens spp. were observed. Of the seven species tested, L. culinaris was the most preferred one for egg laying while L. ervoides was the least preferred. Based on Growth Index (GI), accessions were categorised as highly resistant (15 accessions, GI = 0.00), resistant (14, GI=0.00 to 1.00), moderately resistant (16, GI=1.01 to 2.00) moderately susceptible (3, GI 2.01 to 3.00) susceptible (3, >3.01) to C. chinensis and the species have been arranged in the order of their resistance to C. chinensis. viz L. ervoides > L. lamottei > L. nigricans= L. orientalis > L. culinaris subsp. orientalis= L. culinaris subsp. odemensis > L. culnaris, i.e. L. ervoides was highly resistant and L. culnaris was the most susceptible. Correlation between GI and growth parameters of pulse beetle on different Lens spp. accessions indicated that GI had negative relationship with mean development period (-0.22) and significant positive relationship with adult emergence (+0.73), weight loss (+0.77) and eggs laid (+0.75).

Chickpea (Cicer arietinum L.), is an important pulse food. During storage this commodity is severely attacked by pulse beetle Callosobruchus chinensis L. (Coleoptera: Bruchidae) and losses in quantity and nutritional quality. Research studies on relative resistance of 8 chickpea genotypes to the attack of C. Chinensis during storage were carried out. The maximum number of eggs laid on genotypes ICCV-07301 (34.35) whole minimum numbers of eggs (17.3) were laid on genotypes ICCV-990126. Significantly higher weight loss (24.98%) was noticed SG-98310 which was followed by SG-950226 (16.64 per cent). Least weight loss (5.78 per cent) was observed in SG-97311 closely followed by SG-98004 (6.36%).. The highest per cent infestation was observed in ICCV-08303 (91.66) and the lowest per cent infestation was observed in ICC-920412 (71.66%) closely followed by ICCV-990126(73.33%). The developmental period was recorded longer on deshi genotypes than kabuli genotypes. After 60 days of infestation the protein content increased by 30.03 per cent in kabuli genotypes and by 48.37 per cent in deshi genotypes.
