Anand Agricultural University, Anand

Anand Agricultural University (AAU) was established in 2004 at Anand with the support of the Government of Gujarat, Act No.(Guj 5 of 2004) dated April 29, 2004. Caved out of the erstwhile Gujarat Agricultural University (GAU), the dream institution of Sardar Vallabhbhai Patel and Dr. K. M. Munshi, the AAU was set up to provide support to the farming community in three facets namely education, research and extension activities in Agriculture, Horticulture Engineering, product Processing and Home Science. At present there seven Colleges, seventeen Research Centers and six Extension Education Institute working in nine districts of Gujarat namely Ahmedabad, Anand, Dahod, Kheda, Panchmahal, Vadodara, Mahisagar, Botad and Chhotaudepur AAU's activities have expanded to span newer commodity sectors such as soil health card, bio-diesel, medicinal plants apart from the mandatory ones like rice, maize, tobacco, vegetable crops, fruit crops, forage crops, animal breeding, nutrition and dairy products etc. the core of AAU's operating philosophy however, continues to create the partnership between the rural people and committed academic as the basic for sustainable rural development. In pursuing its various programmes AAU's overall mission is to promote sustainable growth and economic independence in rural society. AAU aims to do this through education, research and extension education. Thus, AAU works towards the empowerment of the farmers.

    GENETIC ANALYSIS OF YIELD AND OTHER QUANTITATIVE CHARACTERS IN FORAGE COWPEA (Vigna unguiculata (L.) Walp.)
    (AAU, Anand, 1982) Kandalkar, Vasant S.; Sanghi, A. K.
    The experimental material consisted of 190 populations which included 10 parents, 45 F1s, 45 F2s and 45B1s and 45 B2s. The experiment was conducted in a compact family block design at the Forage Research Project, Gujarat Agricultural University, Anand Campus, Anand in summer and monsoon seasons of 1980 to obtain information related to gene action, heterosis and inbreeding depression. Observations were recorded on 15 characters, viz., plant height, number of branches per plant, first internode length, stem girth, number of leaves per plant, leaflet length, leaflet width, petiole length, leaf thickness, leaf area per plant, leaf weight per plant, stem weight per plant, leafiness percentage, green fodder and cry matter yield per plant.

    INDUCED MUTATION STUDIES FOR CERTAIN CHEMICAL (CARCINOGENIC) AND AGRONOMIC TRAITS IN BIDI TOBACCO (Nicotiana tabacum L.)
    (AAU, Anand, 1983) Sasikumar, B.; Patel, G. J.
    Tobacco (N. tabaccum) is one of the important cash crops of India. Among the various types of tobacco produced in the country, Bidi tobacco occupies an important position contributing about 38 per cent of the total tobacco production. Over the last two decades a 200 per cent increase in bidi tobacco yield has been attained by improved genotypes developed at Anand. Having achieved this quantitative leas, scientific attention is now being concentrated for the qualitative improvement of bidi tobacco with emphasis on health aspects. It is now more or less well established that bidi smoking is also injurious to health.

    GENETIC STUDIES IN FORAGE SORGHUM (Sorghum bicolor (L.) Moench)
    (AAU, Anand, 1982) PATHAK, HIRA CHAND; Sanghi, A. K.
    Six sorghum male sterile lines were crossed with 18 diverse pollinators in a line x tester design. The resulting 108 hybrids and 24 parents were grown separately in a contiguous block in four environments during kharif, 1981 and were evaluated for 16 forage characters. The objective of the study was to investigate the magnitude of heterosis, combining ability, genetic divergence among parents, character associations, genotype x environment interactions and phenotypic stability of genotypes.

    STUDY OF RECOMBINANT AND POLLEN GRAINS IRRADIATED POPULATIONS OF BIDI TOBACCO
    (AAU, Anand, 1989) PATEL, JAYUSHKUMAR N.; JAISANI, B. G.
    Tobacco is an important cash crop of India. Gujarat occuping second position in tobacco area at national senario enjoys first position for production and productivity. Gujarat produces bidi, chewing, hookah (N. tabacum) and rustica tobacco. Bidi tobacco covers about 85 per cent of the total tobacco hectarage of Gujarat and shares about 90 per cent of the total bidi tobacco production of the country Bidi tobacco is indegenous to India. Considerable crop improvement work has been done in this crop but very limited information is available about the genetic variability for yield and other traits present in this crop as viell as the effect of mutagens on bidi tobacco. The present study was, therefore, taken up at the Bidi Tobacco Research Station, Anand during the years 1985-86 through 1987-88 to study the effect of pollen grains irradiation on the yield and other traits of bidi tobacco (cultivar GT 5), to compare the variability induced by pollen grains irradiation in the M1, M2 and M3, as conpared to the F1, F2 and F3, generations, the interrelationship existing among cured leaf yield and its attributes, as well as to study the response of bidi tobacco M1 and F1 plants to anther culturing. The experimental material comprised of four bidi tobacco varieties viz., Gujarat Tobacco 5 (GT 5), Anand 2 (A 2), Anand 119 (A 119) and Gujarat Tobacco 4 (GT 4); their F1 (GT 5 X A 2, GT 5 X A 119 and GT 5 x GT 4), F2 and F3 generations as well as the M1, M2 and M3 generations of GT 5 where 2, 4 and 6 Kr X-ray irradiated pollen grains were used. The experimental material was studied using randomized block design with four replications during 1985-86 and three replications in the remaining two years of study. The characters studied were days to flower, plant height, number of leaves per plant, leaf length, leaf breadth, spangle score, cured leaf yield per plant, leaf curl incidence, nematode index, nicotine content and sugar content. In vitro pollen embryogenesis response was studied using 10 genotypes viz., four parents, three mutant entries (M1) and three entries of first filial generation. The characters studied were per cent anther response, days to plantlet formation and number of plantlets per productive anther. The results revealed that the genotypes showed significant variation for all the traits studied. Among parents, Gujarat Tobacco 5 was found to be a better parent for plant height, number of leaves per plant, cured leaf yield per plant, leaf curl incidence, root-knot nematode index and nicotine content, while Anand 119 was b e t t e r for early flowering and sugar content, whereas Gujarat Tobacco 4 was better for leaf length and leaf breadth. Among crosses, GT 5 x GT 4 was found to be a better cross for all the traits studied barring days to flower and sugar content. The results further revealed that most of the traits (plant height, leaf length, leaf breadth, cured leaf yield, nematode index and nicotine content) were governed by nonadditive effects. While number of leaves per plant was governed by additive effects. Days to flower was governed by nonadditive as v/ell as additive effects. The findings revealed that pollen grains irradiation at 2,4 and 6 Kr doses of X-ray was not effective to induce genetic variability for developing variants which could either contribute for yield improvement or more tolerance to leaf curl and root-knot nematode diseases than the base parent GT 5 (the best parent for most of the characters). Probably the polyploid nature of the crop was responsible for this behaviour. The cause and effect analysis revealed that number of leaves per plant, plant height, days to flower and leaf breadth were important attributes contributing directly or indirectly to cured leaf yield per plant of bidi tobacco. In order to improve the yield of bidi tobacco, i t would be desirable to develop a gene pool by crossing GT 5 with GT 4 and cyclic method of breeding coupled with inter se mating of desired recombs be used, while selecting elite recombs due weightage should be given to above mentioned traits to develop a cultivar having more cured leaf yield coupled with tolerance to leaf curl and rootknot nematode diseases. The differential behaviour of genotypes for pollen erribryogenesis response was observed for the per cent anther response/ days to plantlet formation and the number of plantlets per productive anther. These traits were governed by non-additivity and were independent of each other. Anand 2 was a better parent for high anther response and early plantlet formation, while A 119 and GT 4 were better for number of plantlets per productive anther. It is feasible to develop a genetype having high anther response, early plantlet formation and more plantlets per productive anther by following cyclic method of breeding involving A 2, A 119 and GT 4 as parents.

    GENETICS OF Pythium aphanidermatum (Edson) Fitz. TOLERANCE IN TOBACCO
    (AAU, Anand, 1983) AMIN, VISHNUPRASAD CHATURBHAI; JAISANI, B. G.
    Damping-off disease of tobacco nursery caused by Pythium aphanidermatum is a serious problem for successful nursery raising. The severity of pre and post emergence damping of may lead to very poor seedling germination ability. High humidity, high temperature and soil moisture show disease symptoms in very short time spell. Due to its easy control by spray of Bordeaux mixture or any other copper compound, it has not been considered a serious problem worth paying attention by the plant breeders. But due to the spiralling prices of copper compounds, lime and labour charges, it is highly essential to evolve damping-off resistant/tolerant cultivars to keep the nursery cost at low level.
