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.

    STUDIES ON VARIABILITY, CORRELATION AND PATH ANALYSIS IN MAIZE (Zea mays L.) FOR FORAGE PURPOSE
    (AAU, Anand, 1997) Amin, Abhishek B.; Patel, J. R.
    Green fodder yield is the most important trait in maize for forage purpose. Knowledge about variability, magnitude and direction of correlation between yield and other component traits can help in selecting better yielding genotype/s. Therefore, the present investigation was undertaken to estimate variability, genetic parameters, genotypic and phenotypic correlations and direct and indirect effects of different characters contributing toward forage yield (green fodder) of maize. The experiment was conducted at the Forage Research Farm, Gujarat Agricultural University, Anand Campus, Anand, during Rabi 1995-96. The experimental material comprised of 11 lines, their Fi, Fz and backcross progoeny. The experiment was conducted in Randomized Block Design with three replications. Total fifteen characters including quantitative and qualitative characters were studied. High genetic gain due to high variability and high heritability could be achieved for crude protein content. Moderate heritability and moderate variability coupled with moderate genetic gain was observed for the characters like fresh stem weight per plant, fresh leaf weight per plant and green fodder yield per metre row length. Whereas, rest of the characters showed low genetic gain with low magnitude of variability and high heritability. Significant and positive correlation at genotypic and phenotypic levels were observed between green fodder yield and plant height, stem diameter, number of nodes per plant, leaf length and breadth, fresh leaf weight and freah stem weight. Path analysis based on genotypic correlation revealed that plant height and leaf breadth had maximum positive direct and indirect effects on green fodder yield. The indirect effects of other characters via these characters were also high. Hence, these characters should be considered for selection of better genotype/s. Stem diameter had negative direct effect but significant and positive genotypic correlation with green fodder yield, so, selection for better plant height and leaf breadth will improve stem diameter.
