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.

    CORRELATION, PATH ANALYSIS AND INHERITANCE STUDIES IN GROUNDNUT ( Arachis hypogaea Linn.)
    (AAU, Anand, 1988) PATEL, RAMESHBHAI I.; PATEL, S. A.
    Twelve parental lines and their twenty two crosses of groundnut were studied to estimate correlation coefficients (genotypic and phenotypic) between different characters as well as phenotypic and genotypic path for pod yield and o il per cent. The inheritance pattern of these qualitative characters along with maturity was also studied. The experiment was carried out at Plant Breeding Farm, B.A. College of Agriculture, Gujarat Agricultural University, Anand Campus, Anand. The replicated t r i a l was conducted in kharif 1987 in Randomised Block Design, Seventeen characters were studied from parents and crosses, Genotypic correlation values were relatively higher than the corresponding phenotypic correlation values in all traits with few exceptions. The yield contributing characters , viz., number of immature pods, nximber of mature pods, kernel yield and shelling per cent were found positively associated with pod yield. Number of primary branches, haulm yield and plant height had negative correlation with pod yield. Oil per cent had positive associations with all these traits which had negative association with pod yield in parents and Fp populations. The correlation of oil per cent with pod yield was positive in parents and negative in F^ populations. Path analysis reveals that kernel yield is the trait which had maximxim direct effect on pod yield. This trait had also influenced pod yield via other yield contributing traits. Haulm yield and number of secondary branches had sizable positive direct effect on oil per cent, Ttius, the study indicate that breeding programme aimed at improvement of pod yield potential of groundnut should be carefully planned and executed through which oil content should not be reduced. The inheritance study reveals that growth habit had monogenic or digenic inheritance in which two complementary nuclear genes and one plasmon interacts to develop semispreading type of plant. The development of flowers on main stem had digenic inheritance and two sets of duplicate genes are working for the expression of this trait. Two pairs of dominant genes having complementary effects were found to govern pod reticulation. Maturity in groundnut had polygenic inheritance, where additive as well as nonadditive genes were involved.

    VARIABILITY AND INHERITANCE STUDIES IN GROUNDNUT (Arachis hypogaea Linn.)
    (AAU, Anand, 1988) CHAUDHARY, DEVENDRAKUMAR N.; PATEL, S. A.
    The present Investigation was under taken with a view to estimate, laroad sense heritablllty, PCV, QCV, EGA and EGA expressed as percentage of mean for sixteen quantitative characters from 12 parental lines and 22 single cross F2 population, Inheritance of oil content, beak and constriction on pod, testa colour and Its variegation were also studied. In parental lines high heritability estimates were observed for days to flower Initiation, number of primary and secondary branches, plant height, 100 pod and kernel weight, oil per cent, haulm yield and harvest Index, Moderate heritability was recorded for number of free pegs, number of mature pods, pod yield, kernel yield and shelling percentage. Number of immature pods and number of keznaels had low heritability in parents. High heritability values were obtained for days to flower initiation, number of mature pods, 100 pod weight, 100 kernel weight, shelling percentage and harvest Index. Plant height, number of free pegs, number of Immature pods, pod yield, kernel yield, number of kernels, haulm yield and oil percentage showed moderate heritability estimate In F2. The rest of the traits showed low heritability in crosses. The GCV estimates were of moderate to low magnitude. Ten traits viz., number of secondary branches, number of free pegs, number of immature pods, number of mature pods, pod yield, kernel yield, number of kernels, 100 kernel weight, haulm weight and harvest index had moderate GCV in parental lines. The rest of the traits had low GCV in parents. In F2, seven traits viz., number of free pegs, number of immature pods, number of mature pods, pod yield, kernel yield, number of kernels and harvest index had moderate GCV, the remaining nine traits had low GCV estimates. The low or moderate values of GCV indicate the presence of little/moderate variability in parents and crosses for these traits. Though the EGA value for most of the traits were lower in F2, wide range of variability was expressed for all the sixteen traits except days to flower initiation and oil percentage in F2 population. This suggest that variability can be profitably exploited for the traits having moderate/high heritability in F2. Among all the traits studied the minimum variability was recorded for oil content and the maximum was recorded for number of immature pods. The results revealed that large number of intersubspecific/interspecific crosses and large scale artificial induction of mutation should be attempted to create large variability in various morphological and physiological traits, which may provide better platform to the breeder for selection. Oil content in groundnut has polygenic Inheritance, The transgressive segregation in F2 reveals the predominant involvement of additive genes in the expression of this trait. Pod beak had monogenic inheritance. Pod constriction was governed by three non allelic genes or their interaction with plasmon. The testa colour had tetragenic inheritance where two basic gene D1D1D2D2 were responsible for pigment production the conversion of pigment to purple or rose colour depends on two pairs of dominant (Pr & T) genes of which Pr had inhibitory effect on T. Testa variegation was governed by two pairs of non allelic dominant genes (V1V1V2V2) having complementary effect.

    VARIABILITY AND CORRELATION STUDIES IN PIGEONPEA (Cajanus cajan (L.) Millsp.)
    (AAU, Anand, 1987) SHAH, KAPILKUMAR J.; PATEL, S. A.
    Legumes are rich source of protein and minerals, able enough to meet the protein requirement of developing countries. Pigeonpea' is one of the important pulse crops of India. The present investigation was undertaken to estimiate variability and genetical parameters (heritability in broad sense, genotypic coefficient of variation, phenotypic coefficient of variation and expected genetic advance as per cent of mean), genotypic and phenotypic correlations as well as direct and indirect effects of different characters on seed yield in pigeonpea. The experiment was conducted at the Plant Breeding Farm of B. A. College of Agriculture, Gujarat Agricultural University, Anand Campus, Anand; in 1984—85 and 1985-86. The experimental material comprised of 25 true breeding genotypes. The experiment was conducted in 5 x 5 simple lattice design. A total of ten agromorphological and five quality characters were studied. The analysis of variance showed significant differences for all the traits except cluster number per plant, seed yield per plant; cooking time, water absorption capacity, methonine content and soluble sugar content. Considering variability and heritability, high genetic gain could be achieved for number of pods per plant, podfly infestation (weight basis) and seed yield. Moderate genetic gain could be achieved for days to 50 per cent flowering, plant height, seed number per pod, seed : pericarp ratio and podfly infestation (number basis). While in case of cluster number, test weight, cooking time and water absorption capacity, low level of the expected genetic gain could be achieved. Out of twenty eight genotypic and phenotypic associations between eight agromorphological characters studied on pooled basis, only two characters viz., number of poda per plant and number of seeds per pod had significant genotypic and phenotypic correlations. The former character showed positive, while the later showed negative correlations. Concluding the findings, it is stated that isolation of a high yielding type with podfly resistance is possible to some extent from these genotypes. Incorporation of podfly resistance in G23 (T-15-15) will help in further improvement in its yield. G21 (BDN 3) and G22 (BDN 2) were among the group of genotypes with less podfly infestation as well as higher yield. For improving the seed yield, importance should be given to pod number followed by seed number' per pod among agromorphological traits. The quality characters require- detail, independent, multi-year trials with more genotypes for fruitful conclusion.
