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.

    STUDY OF VARIABILITY, CORRELATION AND PATH ANALYSIS IN FORAGE SORGHUM [Sorghum bicolor (L.) Moench
    (AAU, Anand, 2012) RANA HARIKRUSHANSINH RAMDEVSINH; Dr. H. R. Kher
    The nature and extent of “variability, Correlation and Path analysis in forage Sorghum. (Sorghum bicolor (L.) Moench.)” were studied in a set of forty genotypes of sorghum grown in randomized block design with three replications at Main Forage Research Station, Anand Agricultural University, during kharif 2011. The observations were recorded viz., Days to 50 per cent flowering, Plant height at 50 % flowering, Number of tillers per plant, Number of leaves per plant, Leaf length, Leaf width, Leaf: stem ratio, Stem girth, Green fodder yield per plant, Dry matter content, Dry matter yield per plant, Crude protein content, Hydrocyanic acid content, Neutral detergent fibre content, Crude fibre content. The analysis of variance revealed significant differences among the genotypes for all the characters studied. This indicated the presence of sufficient variability in the experimental material. A wide range of phenotypic variability was recorded for green fodder yield per plant and its component traits. Higher phenotypic and genotypic variances were observed for days to 50 per cent flowering, plant height, leaf length, green fodder yield per plant, dry matter content, dry matter yield per plant. In the present study magnitude of genetic coefficient of variation (GCV), phenotypic coefficient of variation (PCV), heritability and genetic advance as percentage of mean were recorded high for various characters like leaf: stem ratio, number of leaves per plant, green fodder yield per plant, stem girth and dry matter yield per plant. Therefore, more emphasis should be laid on these component traits, during selection programme for further improvement of green fodder yield per plant. High broad sense heritability estimates were recorded for most of traits viz., days to fifty per cent flowering, leaf: stem ratio, green fodder yield per plant, number of leaves per plant and dry matter yield per plant indicating that these traits were less influenced by the environment. These traits can be improved by simple selection procedure. Genetic advance as percentage of mean was observed high ii for leaf: stem ratio, dry matter yield per plant, green fodder yield per plant, number of leaves per plant and stem girth. It was moderate for number of tillers per plant, leaf width and dry matter content. Correlation analysis suggested that the magnitude of genotypic correlation were higher as compared to their corresponding phenotypic correlations indicating the inherent relationship among the characters studied. Green forage yield per plant was highly significant and positively correlated with stem girth, leaf length, leaf width and dry matter yield per plant at both genotypic and phenotypic level. These characters may be considered as important yield component in sorghum. Path coefficient analysis revealed high positive direct effect of dry matter yield per plant, stem girth and days to fifty per cent flowering. These traits had high magnitude of genotypic correlation with green forage yield per plant. Based on above conclusions, the characters dry matter yield per plant, green fodder yield per plant, number of leaves per plant, stem girth, leaf legth and leaf width had maximum genetic advance under selection and significant positive genotypic correlation along with high direct or indirect effect on green fodder yield per plant. These characters should be used for selection of desirable genotype after hybridization between the accessions for creating wide spectrum of favorable genetic variability for improvement of green fodder yield in sorghum.
