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.

    MOLECULAR DIVERSITY, COMBINING ABILITY AND INHERITANCE STUDIES FOR FERTILITY RESTORATION IN CGMS BASED PIGEONPEA HYBRIDS (Cajanus cajan (L.) Millspaugh.
    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola., 2017-12-21) MESHRAM, MILIND PANDHARI.; Patil, Dr. A. N.
    Present study entitled “Molecular Diversity, Combining Ability and Inheritance Studies for Fertility Restoration in CGMS based Pigeonpea Hybrids (Cajanus cajan (L.) Millspaugh)” was carried out during 2015-2017 at experimental field of Pulses Research Unit and Biotechnology Centre, Department of Agricultural Botany, Dr. P.D.K.V., Akola. Research was undertaken to study the GCA effects of parents and SCA effects of crosses and heterosis studies of hybrids developed by using five CGMS lines with 12 diverse restorers in Line x Tester fashion and evaluated in three different environments during 2016-17. Inheritance of fertility restoration was studied using four crosses during 2014-15 to 2016-17. Diversity of used parents was studied through SSR polymorphism of A, B and R lines. Similarly stable hybrids were identified over three environments. Sixty hybrids, seventeen parents and two checks (PKV TARA and BSMR 736) were evaluated in RBD with three replications over three enviornments Akola, Washim and Badnapur Dist. Jalna during Kharif 2016-17. Observations were recorded on twelve yield and yield contributing traits. The hybrids AKCMS 10A x AKPR 372, AKCMS 13A x AKPR 402, AKCMS 10A x AKPR 364, AKCMS 10A x AKPR 303, AKCMS 10A x AKPR 178 and AKCMS 11A x AKPR 303 showed high positive average heterosis, heterobeltiosis and standard heterosis over the both the commercial checks for seed yield plant-1. These high heterotic hybrids also exhibited higher per se performance, high positive and significant SCA effects and positive GCA effects of one of the parent for seed yield plant-1 with more than 95 per cent plant fertility. Female parent AKCMS 10A exhibited significant and positive GCA effect for seed yield also recorded significant and positive GCA effects for other seven important yield contributing traits. Similarly male parents AKPR 364 for nine traits, AKPR 178 for 8 and AKPR 303 for 7 and AKPR 344 for six important traits including seed yield exhibited significant and desirable GCA effects. Hence these parents can be used in hybrid pigeonpea breeding work. Hybrids AKCMS 10A x AKPR 372, AKCMS 11A x AKPR 372 and AKCMS 13A x AKPR 250 were found stable for seed yield plant-1 along with one or more desirable traits. The crosses showing stability for yield need to be tested for yield across more diverse environments over seasons. The study of genetics of fertility restoration indicated monogenic as well as digenic control of fertility restoring gene. This information is useful for diversification restorer lines in good agronomic background for development of high yielding fertile hybrids. Twenty two parents including 5 CGMS lines, 5 maintainer lines and twelve restorer lines were evaluated to study genetic diversity of parents through SSR polymorphism at Biotechnology Centre, PGI, Akola. Information on molecular diversity revealed that four SSR primers viz., L 240 and PV 14, Cctta005 and Ccat001 which expressed high PIC values indicating their utility for assessment of genetic diversity in pigeon pea. The high range of similarity coefficient values for SSR primers indicating presence of substantial genetic diversity among the studied parents.
