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 STUDIES IN INTERSPECIFIC HYBRIDS OF FORAGE MAIZE (Zea mays L.)
    (AAU, Anand, 2000) PATEL, DIPAK A.; SHUKLA, P. T.
    Fourteen fodder maize genotypes (females) were crossed with three teosinte species (males) in a line x tester design. The resulting 42 interspecific hybrids alongwith 17 parents were grown in a randomized block design with three replications at the Agronomy Farm, B.A. College of Agriculture, Gujarat Agricultural University, Anand during kharif, 1997 and 1998. The main objective of the experiment was to study heterosis, combining ability and nature of gene action for various yield and quality characters. Analysis of variance, in general, revealed significant differences among genotypes (parents and F1S) for yield, its components and quality traits. The genotypes x years interaction was significant for all the characters indicating inconsistent behaviour of genotypes over years. African Tall, IC-130954 and IC-97915, among females and Z. perennis, among males gave the highest green fodder and dry matter yield and were also superior for number of yield components and quality traits. Among hybrids, P13 x P16 (African Tall x Z mexicana), P13 x P15 (African Tall x Z diploperemis) and P2 x P15 (IC-97915 x Z diploperennis) exhibited highest mean performance for green fodder and dry matter yield and also major yield components. In general, the parents showing superior performance gave superior hybrids and higher magnitude of heterosis in hybrid combinations. The highest magnitude of heterosis was observed for fresh stem weight per plant, green fodder yield per plant, dry matter yield per plant, leaf area per plant, crude protein content and stem diameter. On pooled basis, the crosses P2 x P16 (IC-97915 x Z mexicana), P2 x P15 (IC-97915 x Z diploperennis) and P1 x P15 (IC-77101 x Z diploperennis) were most heterotic for green fodder and dry matter yield and also for number of yield components. The hybrids P11 x P15 (IC-130917 X Z diploperennis) and P10 x P16 (IC-130882 x Z mexicana) were the best heterotic hybrids for crude protein content and neutral detergent fibre, respectively. Combining ability analysis indicated the importance of both additive and nonadditive genetic variance for the inheritance of most of the characters in 1998, however the ratio of σ2gca/σ2sca revealed the preponderance of non-additive gene action for all the characters except leaf area per plant. An observation of the general combining ability effects suggested that females African Tall, IC-97915 and IC-130671 were the best general combiners for green fodder and dry matter yield and also for number of yield components. Females IC-130917 and IC-130882 were good general combiners for crude protein content and neutral detergent fibre, respectively. Among male parents, Z diploperennis was the best pollinator for yield and quality traits. Per se performance holds direct relationship with gca effects and hence during parental selection, per se performance should be given due weightage alongwith gca effects. Estimates of sea effects did not reveal any specific trend, however the comparison of sea effects with per se performance of crosses indicated that at least one good general combiner was necessary for better per se performance alongwith high sea effects. On pooled basis, the hybrid P7 x P17 (IC-130730 x Z perennis) was the best specific combination for yield and its major components, whereas P5 x P15 (IC-13 0671 x Z. diploperennis) and P1 x P17 (IC-77101 x Z. perennis) were the best hybrids for crude protein content and neutral detergent fibre, respectively. In view of the preponderance of non-additive gene effect and presence of high magnitude of heterosis and heterobeltiosis in the expression of yield and its attributes particularly during 1998, the exploitation of hybrid vigour on commercial scale is suggested. However, to exploit the additive genetic variance present in sizable proportion for yield and yield components, biparental approach in the segregating generations like F2, using any of the three North Carolina Design or population approach as suggested by Doggett (1972) may be adopted.

    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 ANALYSIS OF GREEN FRUIT YIELD AND ITS COMPONENTS IN CHILLI (Capsicum annuum L.)
    (AAU, Anand, 2000) DOSHI, KETAN M.; SHUKLA, P. T.
    A half diallel set (forty five Fi crosses) including ten parental lines of chilli {Capsicum annuum L.) were grown in a randomized block design with three replications under two environments, kharif as well as rabi season at Vegetable Research Farm, Gujarat Agricultural University, Anand Campus, Anand during 1998-99. The main objective was to study heterosis, combining ability and genetic components following Griffing and Hayman's approach for yield and its components. Analysis of variance for individual environment as well as pooled over environments revealed presence of considerable amount of variability among the genotypes (parents and hybrids) for all the thirteen characters studied. The pooled analysis revealed the presence of high amount of genotype X environment interactions for days to flowering, primary branches per plant, fruits per plant, fruit length, fruit shape index, fruit weight, green fruit yield per plant, days to maturity, total chlorophyll and total capsaicin content. The hybrid, RHRC-16-5 X Guchhedar, BC-14-2 X SG-5 and ACS-92-3 X Guchhedar exhibited maximum heterobeltiosis for green fruit yield per plant on pooled basis.

    GENETICS OF YIELD AS WELL AS SPOTTED BOLLWORM INFESTATION AT SQUARE STAGE AND THEIR ATTRIBUTES IN COTTON (G. hirsutum L.)
    (AAU, Anand, 1990) VASHI, D. R.; JAISANI, B. G.
    Cotton occupies second position for hectarage in the country and ranks first for total production. With a view to increase productivity, a better understanding of the genetics of seed cotton yield and its attributes as tell as resistance / tolerance to spotted bollworm a major deterrent factor in increasing productivity of cotton, is essential. Hence the present study was initiated. The experimental material comprised of the diallel set (excluding reciprocals) of nine elite cotton genotypes. In all , 36 F1s and nine parental lines were sown in randomised block design, replicated twice at Anand. The spacing used was 1.2 m x 0.6 m. The observations on ten characteristics were recorded the data were analysed using Method II , Model 2 of Griffing (1956). The genetics of yield as well as resistance / tolerance to spotted bollworm was studied under natural infestation at square stage using intravarietal recombinant. The inter character association as well as cause and effect relationship (Wright, 1921) were also studied for various traits.

    GENETICAL STUDIES IN OKRA [Abelmoschus esculentus (L.) Moench]
    (AAU, Anand, 2002) KAPADIA, SHAILESHKUMAR ISHWARBHAI; BADAYA, S. N.
    Fifteen females were crossed with five pollinators in a line X tester mating design. The resulting 75 hybrids alongwith 20 parents were grown in a Randomized Block Design with three replications at Plant Breeding Research Farm, Vegetable Research Unit, Gujarat Agricultural University, Anand during Summer and Kharif seasons of 1998-99 and were evaluated for 12 characters. The objective of the study was to investigate the mean performance of parents and hybrids, magnitude of heterosis, components of genetic variances, general combining ability effects of the parents and specific combining ability effects of the hybrids over environments. The analysis of variance, in general, revealed significant differences among genotypes, parents, females vs males, parents vs hybrids and hybrids for fruit yield. early yield, yield components, and the two traits for resistance. The presence of genotypes x environments and hybrids x environments interactionswas observed for all the characters except for days to flower and root-knot index. HRB-55, Sel,-2, KS-404 and KS-312 among females; Pusa Sawani and HRB 9-2 among males and KS-312 x HRB 9-2, Padra 18-6 x HRB 9-2, IC-169354 x HRB 9-2 and Red-1'Long x Dafftari-9 among hybrids expressed the highest mean fruit urtd yield on pooled basis and were also superior for many yield components and resistant/tolerant to YVMV disease and root-knot nematodes. Highly significant and high magnitude of heterosis was observed for all the characters but the hybrids varied in magnitude of heterosis for different characters over environments. In general, superior parents gave superior hybrids and higher magnitude of heterosis in hybrid combinations. The highest magnitude of heterosis was observed for early yield per plant, number of fruits per plant, ftult yield per plant, number of branches per plant and YVMV incidence in that order, A number of crosses showed desirable/significant negative heterosis for days to flower, root-knot index and YVMV incidence. The crosses, KS-312 x HRB 9-2, Padra 18-6 x HRB 9-2, IC-169354 x HRB 9-2 and Red-1'Long x Dafftari-9 exhibited highest magnitude of standard heterosis for fmit yield on pooled basis and were also relatively high in individual environments.
