    SODIUM AZIDE INDUCED GENETIC VARIABILITY IN M4 GENERATION OF INDIAN MUSTARD (Brassica juncea) coss.
    (Dr. Punjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-06-26) PRAJAPATI, SHAILENDRA SAGAR.; Nair, Dr. Beena
    The present study was carried out with the objectives to estimate variances between family and within family in M4 generation, to estimate genetic parameters in M4 generation and to identify superior mutants in M4 generation for further utilization, at experimental farm of AICRP Linseed and Mustard, College of Agriculture Nagpur during rabi 2019 in M4 generation. In rabi 2019, 161 mutants along with three checks (PM 21, Kranti and Shatabdi) were evaluated in M4 generation in two replication. Data were recorded on days to 50% flowering, days to maturity, plant height, number of primary branches plant-1, number of siliqua plant-1, number of seed siliqua-1, length of siliqua, seed yield plant-1 and 1000 seed weight were recorded. Analysis of variance indicated that the mean squares due to between family were highly significant for all traits, revealing the presence of significant genetic variability between the families. Intra class correlation (t) lead the conclusion that differences between individuals within family is large and each family differentiated distinctly from the other one at lower level in M4 generation hence, equal weightage to σ2f and σ2w were suggested to be considered for selection in M4¬ generation. The genetic parameter analysis revealed the importance of number of siliqua plant-1 and seed yield plant-1 for selection of better individual mutant from the progenies, based on genotypic coefficient of variation, phenotypic coefficient of variation, heritability and genetic advance. In M5 generation 93 individual plants from progeny were selected from 161 mutants of M4 generation. These mutants will be further evaluated in M5 generation and those found superior will be forwarded to yield trials.

    GENETIC VARIABILITY STUDIES IN M5 GENERATION OF MUSTARD.
    (Dr. Punjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-07-31) HOSUR, PRAKASH LAXMAPPA.; Nair, Dr. B.
    The present study was conducted with the objectives to estimate genetic variability of the selected mutants based on morphological characters and selection of superior mutants from M5 generation of mustard at AICRP on Linseed and Mustard farm of College of Agriculture Nagpur during rabi 2018 in M5 generation. In rabi2018, 26 advanced mutants along with four checks (Bio 902, Pusa bold, Kranti, Shatabdi) were evaluated in randomized block design in three replication. Data were recorded on days to 50% flowering, days to maturity, plant height, number of primary branches plant-1, number of siliqua plant-1, number of seeds siliqua-1, length of siliqua, seed yield plant-1 and 1000 seed weight. Diversity analysis of 10 high yielding advanced mutants was also done using 20 SSR primers. Analysis of variance indicated that the mean square due to between family and within family were highly significant for all traits, revealing the presence of significant genetic variability between the families. Intra class correlation (t) lead the conclusion that each family distinctly differentiated from each other and differences between individuals within a family is large for all the characters. Therefore it was suggested to assign more weightage to σ2f than σ2w for selection in this generation. The genetic parameter analysis revealed the importance of number of siliqua plant-1 and seed yield plant-1 for selection of better individual mutant from the progenies, based on genotypic coefficient of variation, phenotypic coefficient of variation, heritability and genetic advance. In M5 generation 8 high yielding plants from 26 advanced mutants were selected. Twenty SSR primers were used to evaluate 10 mutant genotypes of mustard. The PCR amplified products of each primer were resolved on 3% agarose gel electrophoresis. Out of 20 SSR primers screened during present study, 12 primers viz.,Na14E08, Na10G10, OI11B05, OI12E03, OI10F06, Ni4H05, Ni2E12, Ni2H06, Ni2Co1, Ni4G09b, Ra2DO4 and OI10F09were found monomorphic and eight primers viz., Na12E01, Na10E02, OI10E05, Na12A08, Na12D04, Na12F11, Ra2E12 and Ra2A11 were found polymorphic for the set of selected genotypes. And based on banding pattern dendrogram was generated for better understanding of the diversity among the selected mutants. Eight mutants viz., ACNMM 20, ACNMM 23, ACNMM 17, ACNMM 12, ACNMM 22, ACNMM 1, ACNMM 3 and ACNMM 9 were selected on the basis of yield and some of these mutants viz., ACNMM 23, ACNMM 22, ACNMM 13, ACNMM 14, ACNMM 7 were observed to be diverse from the checks as they appeared in different clades as that of checks. Some of them were found similar to the checks viz., ACNMM 9, ACNMM 4, ACNMM 17, ACNMM 19 to BIO-902 and ACNMM 15 to Kranti as they occupied the same clade as that of the check. These superior mutants will be further evaluated in multilocation trials of superior and diverse genotypes which can be released as variety or used in breeding programme.

    HETEROSIS AND COMBINING ABILITY ANALYSIS FOR YIELD AND ITS COMPONENT TRAITS IN MAIZE (Zea mays L.)
    (Dr. Punjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-08-05) CHAVAN, PAVAN BALIRAM.; Moon, Shri. M. K.
    Thirty F1 crosses were developed from six parents through full diallel mating design was evaluated for ten characters to estimate magnitude of heterosis and combining ability effect of parents, specific combining ability and reciprocal combining ability effect of crosses and to identify potential F1’s for advancing in further. Six parents and thirty crosses along with two checks Maharaja and Rajarshi were raised in adjacent plot in RBD replicated twice with spacing of 60 X 20 cm and recorded observation on days to 50% tasseling, days to 50% silking, days to maturity, plant height (cm), cob length (cm), cob girth (cm), number of grains cob-1, 100 grain weight (g), grain yield plant-1 and grain yield plot-1. All the crosses exhibited significant heterosis in positive and negative direction. The means squares due to general combining ability and specific combining ability were significant for all the characters and means squares due to reciprocal combining ability significant for all the characters except days to 50% tasseling and cob girth. CM145, CM152 and CM123 are the parents were identified as good general combiner for yield and other yield contributing characters. These genotypes were may be recommended for their use in the crossing programme or for developing gene pool. High mean performance, significant useful heterosis, in desirable direction and positive significance sca/rca effect were considered as the criteria for selection of potential crosses. Based on above criteria the crosses UMI1200 X CM152, CM152 X CM145, CM152 X UMI1200 and UMI1200 X CM124 were identified to exhibit high mean, significant positive heterosis over both the checks and significant positive combining ability for grain yield plant-1 and other yield contributing characters.
