In the autumn of 2008, Vigna mungo var. silvestris growing in the experimental field of the Indian Institute of Pulses Research, Kanpur, India, showed chlorosis around some lateral veins and vein branches (mainly near the leaflet margin), downward curling of the leaf margins, necrosis of the stems and petioles, and twisting of the leaflets. Disease incidence was 20%. Symptoms indicated that the cause was Groundnut bud necrosis virus. The virus was identified on the basis of the symptoms on the diagnostic host, and the reverse transcription polymerase chain reaction (RT-PCR) using specific primers of the NSm and NP genes. To our knowledge this is the first report of Groundnut bud necrosis virus on V. mungo var. silvestris.

An experiment consisting of twenty-one maize hybrids was conducted during kharif 2012 at Oilseeds Research Farm, Kalyanpur, Kanpur. Each genotype was sown in two rows each of 4 meter long spaced at 60×25 cm between rows and plants respectively in a randomized complete block design in three replications. The observations were recorded on five randomly selected plants for chlorophyll intensity at 30 and 60 DAS, Proline content (mm) at 60 DAS, Dry weight/plant at the intervals of 30, 60 and 90 DAS, cob weight per plant (g) and protein content. The statistical and biometrical analysis was carried out using standard formula. The results showed high heritability coupled with high genetic advance for total dry weight at maturity followed by cob yield per plant, dry weight at 60 DAS and proline content at 60 DAS reflecting the role of additive gene action. High heritability and low genetic advance was observed for chlorophyll intensity at 30 and 60 DAS and plant dry weight at 30 DAS indicating the presence of both additive and non-additive genes for controlling the characters. Cob yield per plant showed positive and significant correlation with plant dry weight at maturity. Its association with plant dry weight at 60 DAS was negatively significant. © 2016, Indian Society of Agricultural Biochemists. All rights reserved.

Genetic analysis was carried out to determine the mode of inheritance of resistance to bud fly which is a key pest of linseed during flowering stage. Parents, F1, F2, BC1 and BC2 populations of three crosses involving two resistant, IC 15888 and JRF4 and two susceptible parents, viz., Neelum and GS-41 were the experimental materials. Reaction to bud fly in F1s of all the three crosses indicated that resistance was dominant over susceptibility. The F2 and back cross segregants were categorized in to resistant and susceptible classes based on per cent bud infestation. The genetic analysis in F2 generation revealed that two dominant complementary genes in IC 15888 control the bud fly resistance, while JRF 4 carried a single dominant gene for resistance. The F2 results were confirmed by genetic analysis of back cross populations. It can be categorically stated that the knowledge of number and nature of resistance genes in IC 15888 and JRF4 will be valuable for development of bud fly resistant varieties in linsee. © 2015, Indian Society of Genetics and Plant Breeding.

This experiment was conducted during kharif season-2013, in randomized Block Design with three replications on rice variety (Usar Dhan-3) at The Main Experiment Station, Narendra Deva University of Agriculture & Technology, Kumarganj, Faizabad. The Seven treatments as T1-control, T2-25 kg/ha ZnSO4, T3-50 kg/ha ZnSO4, T4-25 kg/ha ZnSO4 + foliar spray of cytokinin 25 ppm, T5-50 kg/ha ZnSO4 + foliar spray of cytokinin 25 ppm, T6-25 kg/ha ZnSO4 + foliar spray of cytokinin 50 ppm, T7-50 kg/ha ZnSO4 + foliar spray of cytokinin 50 ppm were used for experimentation under sodic soil condition. The observation were recorded at 30, 60, 90, and maturity stages of crop. Among the treatments T7-50 kg/ha ZnSO4 + foliar spray of cytokinin 50 ppm at 45 DAT increased significantly máximum relative wáter content (%), carbohydrate content (mg g-1 dry wt.), chlorophyll content, number of tiller hill-1 at all crop growth stases, number of grain hill-1, grain yield (q ha-1) and test weight (g) were recorded in comparison to control (T1).

An experiment was carried out during two subsequent years, i.e., 2009-10 and 2010-11 to study the influence of Azotobacter, vermicompost on growth, flowering, yield and quality of strawberry cv. Chandler. There were nine treatments comprising two levels each of Azotobacter (6 and 7 kg/ha) and vermicompost (20 and 30 t/ ha) and their combinations along with one control, replicated thrice in randomized block design. Five kg of FYM was applied as a basal dose in all the treatments including control. All the doses of Azotobacter and vermicompost were applied at the time of planting in the field. The data of both the years of experiment were pooled and analyzed. The combined application of Azotobacter at 7 kg/ha + vermicompost at 30 t/ha significantly increased the height of plant (18.70 cm), number of leaves (61.60), crowns (6.77) and runners (4.83) per plant, whereas, maximum number of flowers (56.69), fruits set (25.87) per plant with increased duration of harvesting (66.80 days) and minimum number of days taken to produce first flower (55.17 days) and fruit set (6.19 days) with significantly more yield (322.38 g/plant) were observed with Azotobacter at 6 kg/ha + vermicompost at 30 t/ha applied plants. Plants fertilized with Azotobacter at 6 kg/ha + vermicompost at 30 t/ha also produced the berries with maximum length (4.76 cm), width (2.49 cm), weight (8.75 g), volume (5.97 cc), TSS (9.800Brix), total sugars (9.23%), ascorbic acid (54.72 mg/100 g edible portion) with minimum titratable acidity (0.50%) in comparison to other treatments under plains of central Uttar Pradesh. © 2015, Horticulture Society of India.
