Genetic analysis of seed

Genetic analysis of seed yield and quantitative traits in pigeonpea (Cajanus cajan L. Millsp.)



M. B. Parmar, K. B. Kathiria





Abstract : Success of breeding programme depends upon the nature of gene action involved in controlling the traits. Hence, the present study was conducted using six generations (P1, P2, F1, F2, B1 and B2) of the crosses T 15-15 BSMR 853, AVPP 1 LRG 41, AGT 2 ICP 8863 and GT 101 ICPL 84060 of pigeonpea to know significance of additive-dominance model, nature of gene action, heterosis and inbreeding depression. The individual scaling test and χ2 value of joint scaling test was significant with all the crosses for most of the quantitative traits. Non-additive gene action was important for seed yield per plant while additive and non-additive effects were found to be more pronounced for yield contributing traits. Dominace x dominance inter-allelic interaction (l) was more important than additive x additive (i) for the traits days to 50 per cent flowering, days to maturity, plant height,

Evaluation of probiotic potential of novel

       Evaluation of probiotic potential of novel candidate Enterobacter avium strain  chick faecalborne Alcaligenes faecalis

ABSTRACT:

                             Consumers and regulatory agencies have reduced or even eliminated the use of antibiotics in food producing animals. This created a need to find alternatives to maintain healthy and productive animals. Probiotics were employed as a good alternative treatment strategy through oral bacteriotherapy for curing many diseases of human and animals. The present work was performed to isolate and characterized properties of probiotic Enterococci. For this purpose the antagonistic activity of E. avium probiotic was evaluated which posses the ability to suppress growth of opportunistic pathogen A. faecalis associated with bacteremia and respiratory infections in chick. As the E. avium fed chick recovered and showed improved growth and body weight they offers a potential novel candidate for controlling infection in chick
