Stability in Phenology, Yield and Yield Attributes of Chickpea (Cicer arietinum L.) Genotypes under Various Temperature Conditions

An experiment was conducted with a set twenty-five genotypes of desi and Kabuli chickpeas to estimate stability parameters in Randomized Block Design with two replications under four environments (1st November 2018 (normal), 21st November 2018 (optimum), 15th December 2018 (late) and 15th January 2019 (extremely late) conditions during Rabi-2018-19. The analysis of variance showed a significant connection among genotypes, environment (linear), and genotype environment (linear) in all the traits in investigation. The JG-11, JAKI-9218, RVG-201 and RVSSG-54 these genotypes suitable for high seed yield with late and very-late sown conditions

Exploring the Chickpea Genotypes through Morphological Characterization for Improved Breeding

Morphological characterization is a valuable approach used to examine observable traits in crop plants, enabling the identification, classification, and understanding of genetic variations within diverse genotypes. This supports breeders in selecting desirable traits and improving breeding programs. Thus, the aim of this study is to investigate the morphological characterization of 40 chickpea genotypes, focusing on 20 morphological traits, following the DUS testing guidelines proposed by PPV & FRA, GOI, 2007. The experimental study was carried out utilizing the randomized complete block design (RCBD) at the Seed Breeding Farm, Department of Plant Breeding and Genetics, College of Agriculture, JNKVV, Jabalpur, M. P. Through the examination of these traits, distinct patterns were identified among the chickpea genotypes. Among the 20 traits analyzed, 5 traits exhibited a monomorphic pattern, 8 traits displayed a dimorphic pattern, 6 traits demonstrated a trimorphic pattern, while the remaining 1 trait revealed a polymorphic pattern. These results indicate a substantial degree of genetic variability within the studied chickpea genotypes, emphasizing the diverse nature of these traits that can be harnessed for targeted breeding efforts and highlighting the immense potential for the development of improved chickpea varieties

Comparative Analysis of the Effect of Different Insecticide Treatments on Nagpur Mandarin in Biomass Accumulation

The Comparative Analysis of the Effect of Different Insecticide Treatments in Nagpur Mandarin on Biomass Accumulation was conducted during the Ambia bahar of 2009-10. The experiment was carried out on an eight-year-old Nagpur mandarin orchard with a spacing of 6.0 m x 6.0 m at Futala farm, College of Agriculture, Nagpur. The study aimed to assess the impact of different insecticide treatments on Citrus psylla management. A trial comprising of eleven treatments was set in the Randomized Block Design (RBD), replicated thrice, with each treatment plot having four plants. Four branches were selected from each plant at random and tagged. The population of citrus psylla (both nymph and adult) was counted on the twigs of 5 cm fresh growth of the shoot from all the four sides of the plant during Ambia bahar of 2009-2010. The study found that imidacloprid 0.25 ml/l, acetamiprid 0.1 g/l, and quinalphos 1 ml/l + karanj oil (pongamia oil) 10 ml/l were the most effective treatments based on biomass accumulation (wet weight basis). Meanwhile, treatments with lower efficacy were Verticillium lecani 4 g/l + mineral oil 5 ml/l, azadirachtin 2 ml/l, mineral oil 5 ml/l, and Verticillium lecani 4 g/l. Furthermore, the application of imidacloprid 0.25 ml/l, acetamiprid 0.1 g/l, thiomethoxam 0.1 g/l, and quinalphos 1 ml/l + karanj oil (pongamia oil) 10 ml/l were found to be the most effective treatments based on biomass accumulation on a dry weight basis. The results indicated that treatments with imidacloprid, acetamiprid, thiomethoxam, and quinalphos with karanj oil were the most effective in promoting higher growth of new flush, bearing (buds, flowers and fruit), and biomass accumulation on both wet weight and dry weight basis. Among them, the treatment with imidacloprid at 0.25 ml/l was found to be the most effective
