Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola

Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola was established on 20th October, 1969 with its head-quarter at Akola. This Agricultural University was named after the illustrious son of Vidarbha Dr. Panjabrao (alias Bhausaheb) Deshmukh, who was the Minister for Agriculture,Govt. of India. The jurisdiction of this university is spread over the eleven districts of Vidarbha. According to the University Act 1983 (of the Government of Maharashtra), the University is entrusted with the responsibility of agricultural education, research and extension education alongwith breeder and foundation seed programme. The University has its main campus at Akola. The instructional programmes at main campus are spread over in 5 Colleges namely, College of Agriculture, College of Agricultural Engineering & Technology, College of Forestry, College of Horticulture and Post Graduate Institute. At this campus 4 degree programmes namely B.Sc.(Agri.) B.Sc. (Hort.), B.Sc. (Forestry) and B.Tech. (Ag. Engg.) , two Master’s Degree Programmes viz. M.Sc.(Agri.) and M.Tech. (Agri.Engg.) and Doctoral Degree Programmes in the faculties of Agriculture and Agril. Engineering are offered. The University has its sub-campus at Nagpur with constituent College, College of Agriculture which offers B.Sc.(Agri.) and M.Sc.(Agri.) degree programmes. The Nagpur Campus is accomplished with a garden, surrounded by its natural beauty and a well established Zoo which attract the general public and visitors to the city. A separate botanic Garden is being maintained on 22 hectares with a green house for the benefit of research workers. In addition there are 2 affiliated grant-in-aid colleges and 14 private non-grant-in-aid colleges under the umbrella of this University A Central Research Station is situated at the main Campus which caters to the need of research projects undertaken by Crop Scientists of the principle crops of the region are Cotton, Sorghum, Oilseeds and Pulses.

    Genetic and stability analysis in F6 and F7 population of vegetable and grain type soybean (Glycine max (l.) Merrill.).
    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2021-09-08) PARDESHI, PRIYA PRADIPSINGH.; Nandanwar, Dr. R. S.
    Vegetable soybean [Glycine max (L.) Merill] is rich in protein than any other pulse crop. It is also a rich source of calcium, iron, zinc potassium, ascorbic acid, and vitamin E. So, it can be a better fresh vegetable source to combat malnutrition in India. After harvesting pods at the green stage, the leaves can be used as green manure. With all these advantages, the vegetable soybean is not popular in India. Hence, an attempt has been made to screen the vegetable soybean based on physiological parameters, yield, yield attributes, the present study was carried out to know variability, heritability and association, and stability among various traits in a set of vegetable genotypes. The study was carried out in two Kharif season viz., Kharif 2017-18, and Kharif 2018-19. In Kharif 2017-18, 80 advanced genotypes derived from cross of vegetable and grain type soybean advanced population were analyzed for the presence of trait variation at Seed Testing Research Unit (STRU), Dr. Panjabrao Deshmukh Krishi Vidyapeeth (Dr. PDKV), Akola. During the subsequent season, Kharif, 2018-19 selected 21 lines of vegetable soybean were assessed for the stability of yield, carbohydrate (%), protein content (%), and oil content (%) at R6 stage across the three different locations of Maharashtra. Eighty selected lines were evaluated by using randomized block design with three replicates for the estimation of genetic variability, heritability, genetic advance and correlation. ANOVA revealed the presence of statistically significant treatment mean sum of squares for all the nineteen characters studied. The greater value of PCV and GCV were noted for green pod yield per plant, 100 green seed weight per plant, 100 mature seed weight, green seed yield per plant, seed weight per plant, carbohydrate content in the R8 stage. High heritability coupled with high genetic advance over a mean (GAM) was observed for most of the quantitative and qualitative traits. Association analysis revealed the positive association between green pod yield per plant (g) with 100 green and mature seed weight and green seed yield per plant. Micronutrient analysis revealed that at green stage line VS-1-13-17 and line VS-1-16-17 had maximum zinc content while, line VS-4-184-17, line VS-5-276-17, and line VS-3-99-17 had highest Iron content, copper content, and magnesium content respectively. On the bases of desirable traits, superior lines have been selected. Selected 21 lines of vegetable soybean were assessed for the stability of selected traits. The AMMI analysis of variance indicated highly significant effects of the environment (E), genotype (G), and genotype × environment (GE) effects for all three yields contributing trait. Most stable genotype for green pod yield and green seed yield per plant across the location was VS-2-141-17, VS-3-99-17, and VS-5-276-17,100 green seed weight, line VS-3-99-17, VS-4-245-17, VS-5-265-17, VS-5-173-17 identified as a stable line while, for oil content line VS-1-28-17, VS-1-80-17, VS-4-227-17, VS-2-141-17, and VS-4-198-17 found stable. Considering carbohydrate content most of the genotype under consideration was found to be stable. For protein content in green stage lines VS-1-28-17, VS-1-80-17, VS-2-128-17, VS-4-227-17, VS-4-238-17, VS-5-276-17, and VS-5-266-17 found to be stable across the location. We also studied the genetic diversity of using 60 polymorphic SSR markers. A total of 203 alleles were detected across the 21 genotypes with a mean of 3.96 alleles that ranged from 2 to 8 alleles per locus. The polymorphism information content varied from 0.05 to 0.85 with an average value of 0.60. The variation of 0.25 to 0.58 with a mean of 0.43 was observed for Jaccard's dissimilarity coefficient. Cluster analyses grouped genotypes into three major clusters depicting the diversity of the vegetable soybean lines. The same has also been validated through principal coordinate analysis. The evaluation of agro-physiological traits also showed the presence of wide variation among lines. Along with that morphological and biochemical characters were used to develop the identification key for the establishment of distinctness among these advanced lines. According to the scorecard of organoleptic evaluation line VS-1-75-17, VS-4-223 -17, VS-5-273-17 and VS-4-244-17 was the best genotypes for the color and appearance, texture, aroma, taste, and overall acceptability. Lines identify in the present study can be used for further breeding program.
