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.

    The present investigation entitled “Genetic and molecular analysis in vegetable and grain type soybean (Glycine max (L.) Merrill)” was undertaken to characterize and analyse proximate composition of vegetable and grain type soybean genotypes, genetic inheritance of contrasting characters and characterization of promising crosses at molecular level. Morphological characterization and genetic variability studies were carried out using fourteen soybean genotypes including seven each of grain and vegetable types during Kharif 2016-17. The experimental populations of five different crosses (F1’s, backcrosses with both parents and F2) were developed during Kharif 2016-17 to 2017-18 for genetic inheritance studies. Evaluation of all the populations along with their parents and molecular work was carried out at experimental field of Department of Agricultural Botany and Biotechnology Centre, Dr. PDKV, Akola, respectively during 2018-19. Ten characters were recorded for morphological characterization of soybean genotypes and categorized based on the expression of distinguishable morphological traits with two to four expressions. Analysis of variance indicated significant differences among the genotypes for different traits. The phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV). The high values of GCV and PCV observed for 100 green seed (bean) weight, 100 seed (matured) weight, seed yield per plant, green seed (bean) yield per plant and harvest index. High heritability coupled with high genetic advance was observed for days to 50% flowering, days to maturity, plant height, number of branches per plant, number of seed per pod, green pod weight per plant, 100 green seed (bean), 100 seed weight, green seed (bean) yield per plant, seed yield per plant, harvest index, oil content, protein content, iron content, zinc content and trypsin inhibitor content showed preponderance of additive gene effects in expression of these traits. Among the soybean genotypes, Swarna Vasundhara was found promising for green pod weight, seed yield per plant, harvest index and protein content at R6 stage. The genotype AGS-450 exhibited high iron with low trypsin content whereas, AGS-459 exhibited high sugar and zinc content with aroma, soft texture and sweet taste. Eight contrasting characters (leaf shape, flower colour, pod pubescence, pod pubescence colour, pod colour, plant height, seed colour and seed shape) used for genetic inheritance studies. All contrasting traits were governed by single gene with complete dominance, except leaf shape in crosses Swarna Vasundhara X JS(SH)93-37 and AGS-339 X JS(SH)93-37, plant height in three crosses viz. Swarna Vasundhara X JS(SH)93-37, GC-84501-32-01 X JS(SH)93-37and AGS-450 X JS(SH)93-37 and seed shape in cross Swarna Vasundhara X JS(SH)93-37 showed complementary gene interaction (9:7). Plant height also showed duplicate gene interaction (15:1) in cross AGS-339 X JS(SH)93-37 and seed colour in cross Swarna Vasundhara X JS(SH)93-37 showed supplementary gene interaction (9:3:4) indicating two genes were responsible for these traits. Characterization of fourteen soybean genotypes and six parents along with sixteen selected desirable lines of five crosses carried out by using molecular markers. Among soybean genotypes, thirteen SSR primers found polymorphic and the similarity matrix coefficient ranged from 0.323 to 0.905. Eleven SSR primers (Simple sequence repeat) were found to be polymorphic among the six parents and their selected lines and the similarity matrix coefficient ranged from 0.310 to 0.818. Dendrogram analysis depicted six clusters with huge genetic diversity in all soybean genotypes including vegetable and grain type whereas, three clusters in parents and desirable lines at molecular level. Present investigation on characterization and genetic variability can be used to measure the extent of variation in various morphological characters, transmissibility of character from parent to their offspring and genetic gain from the selection applied in population. Genetic inheritance studies can guide soybean breeders for transfer of contrasting traits in desirable genotypes by using appropriate breeding strategy and molecular characterization study will be helpful in identification of genetically diverse soybean genotypes, parents and advanced lines for broadening the genetic base and improving the breeding efficiency.
