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.

    Title: EVALUATION OF ORGANICALLY GROWN COTTON GENOTYPES FOR INSECT PESTS TOLERANCE.
    (Dr.Panjabrao Deashmukh,Krishi Vidyapeet,Akola, 2021-08-13) Authors: AHERKAR, SHRADHA SHRIKANT.; Advisor: Deshmukh, Dr. S. B.
    Abstract: The research work entitled, “Evaluation of organically grown cotton genotypes for insect pest tolerance” conducted at Centre of Organic Agriculture Research and Training (COART), Department of Agronomy, Dr. PDKV, Akola during the kharif season 2020-21; was undertaken to study the reaction of cotton genotypes against insect-pest under organic condition as well as to study the correlation between the insect-pest with its associated characters and seed cotton yield. The experiment comprised of 22 cotton genotypes (20 SGF cotton genotypes and one resistant check DHY-286 and one susceptible check DCH-32) which were replicated thrice under Randomized Block Design. The data regarding sucking pest was recorded at 45, 60, 90 and 120 DAS, whereas, per cent bollworm infestation was recorded at 60, 90 and 120 DAS. In the similar way, data of morpho-physiological characters i.e. number of gossypol glands per cm2, hair (trichomes) density per cm2 and chlorophyll content index; data of biochemical characters i.e. total soluble sugar, total nitrogen and crude protein was recorded at 45, 60, 90 and 120 DAS. The observations on yield and yield contributing characters i.e. days to 50 per cent flowering, days to 50 per cent boll bursting, plant height, number of bolls per plant, boll weight, number of sympodia per plant, number of monopodia per plant and seed cotton yield were recorded at maturity stage of the cotton crop. From the present study, it was concluded that, genotypes AKH-9916, AV-C14, DHY-286, AKH 09-5, Nirmal 996 and GA-8004 recorded maximum trichome density per cm2 as well as maximum gossypol glands per cm2, however, on the other hand, less amount of chlorophyll content, total soluble sugar, total nitrogen and crude protein was recorded in these genotypes. These genotypes also recorded least population of aphids, leafhoppers, thrips and less per cent bollworm infestation. Whereas, genotypes GH-8032, DCH-32, Chetna-S1, Raja-954 and Bhakti-245 had tolerant reaction towards whitefly and showed less trichome density per cm2 and less gossypol glands per cm2 but these genotypes recorded higher content of chlorophyll, total soluble sugar, total nitrogen and crude protein. The American cotton varieties AKH 09-5, GH-8001E and Suraj, American cotton hybrid Nirmal 996, desi cotton variety GA-8004 and desi cotton hybrid Namaskar_Gold-81 recorded comparatively higher yield and higher mean values for trichome density per cm2 and gossypol glands per cm2 and lower mean values for chlorophyll content, total soluble sugar, total nitrogen and crude protein under unprotected organic conditions which are desirable from pest tolerance point of view. The correlation studies revealed that, trichome density and gossypol glands had negative and significant correlation with aphids, leafhoppers and thrips but had positive and significant correlation with whitefly. Whereas, total soluble sugar, total nitrogen as well as crude protein had positive and significant correlation with aphids, leafhoppers and thrips but had negative significant correlation with whitefly. On the other hand, the bollworm damage had negative and significant correlation with trichome density. However, positive and significant correlation was also observed between the bollworm damage and chlorophyll content, total soluble sugar, total nitrogen and crude protein.

    Evaluation of parents and hybrids using Line x Tester analysis for seed yield and its components in safflower (Carthamus tinctorius L.).
    (Dr.Panjabrao Deshmukh Krish Vidyapeet,Akola, 2022-09-27) GARG, ARZOO.; Gawande, Dr. V. L.
    The present investigation was carried out to know the magnitude of heterosis, combining ability of parents and crosses for yield, its contributing traits and oil content. Thirty crosses [obtained by crossing two females (testers) with fifteen males (lines)], along with seventeen parents and three checks viz., PBNS 12, PKV Pink and A1 were evaluated in Randomized Block design during rabi 2019-20 with three replications at experimental field of Department of Agril. Botany, Dr.PDKV, Akola and observations were recorded for seed yield, yield contributing traits and oil content. Analysis of variance indicated presence of substantial genetic variability for the characters studied. The highest magnitude of heterosis over both standard checks and better parent for the traits days to 50 % flowering was noticed in AKS CMS 3A x GMU 2830 and in cross AKS CMS 3A x GMU 590 for days to maturity over mid and better parent. Maximum heterosis for seed yield per plant was exhibited by hybrid AKS CMS 3A x GMU 2273 over mid parent, over better parent and over standard check. Further, AKS CMS 2A x GMU 6891 exhibited significant average heterosis, heterobeltiosis for oil content. Whereas AKS CMS 2A x GMU 7573 exhibited maximum useful heterosis for oil content. The parents, GMU 590, GMU 2273 and GMU 589 among the lines and AKS CMS 3A among the testers were found to possess good GCA effects for seed yield and most of yield contributing characters. For oil content, GMU 7573, GMU 2273 and GMU 2830 among lines were best general combiners. These parents can be used in further breeding programme for improvement of concerned trait. The crosses AKS CMS 2A x GMU 1731 and AKS CMS 3A x GMU 7448 were good specific combinations for number of capsules per plant, and seed volume weight. Whereas, crosses AKS CMS 3A x GMU 2273, AKS CMS 2A x GMU 6891 were for seed yield per plant and seed filling percentage. Three promising crosses viz., AKS CMS 3A x GMU 2273, AKS CMS 3A x GMU 590 and AKS CMS 3A x GMU 589 identified on the basis of high mean, significant SCA effects and high heterosis over best check in desirable direction were detected. These crosses may be exploited for heterosis breeding and also for isolating desirable recombinants from advanced segregating generations (by using “B” line of CMS based testers along same male parent in concerned cross). Intermating plants from early segregating gnerations may be done to break undesirable linkages and to isolate desirable segregants for yield and contributing traits due to predominance of SCA variance.
