    (Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, 2020-09-30) TAMBITKAR, NARESH BHIVA; Pethe, U. B.
    The present experiment entitled “Genetic diversity studies in cowpea (Vignaunguiculata (L.) Walp)”was undertaken to assess the genetic variability, genetic divergence and path analysis in forty-one genotypes of cowpea in randomized block design with two replications at educational and research farm, Department of Agril. Botany, College of Agriculture, Dapoli, Dist. Ratnagiri, Maharashtra during rabi 2019-2020. The estimates of phenotypic, genotypic and environmental variance revealed that phenotypic variance were higher in magnitude than genotypic variance for all the characters. The magnitude of phenotypic and genotypic variance was closer to each other for majority of the characters thus indicating lesser role of environment in the expression of these characters. In general, phenotypic coefficient of variation (PCV) was higher in magnitude over genotypic coefficient of variation (GCV) for all the characters. Different characters showed varying per cent of coefficient of variation both genotypic and phenotypic levels. High genotypic and phenotypic coefficient of variation was observed for the characters iron content (ppm) , plant height at maturity (cm), seed yield per plant (%), days to maturity, dry matter yield per plant (g), while this were low for the characters days to fifty percent flowering. In present investigation, the genotypic correlation coefficient was higher in magnitude than their phenotypic counter parts for most of characters. Dry matter yield per plant and harvest index exhibited highly significant positive correlation with seed yield per plant both phenotypic and genotypic levels. The characters number of primary branches per plant, hundred seed weight, number of pods per plant, iron content, days to 50 % flowering, number of seeds per pod and protein content had non-significant positive correlation with seed yield per plant at both phenotypic and genotypic levels. Forty-one genotypes were grouped into 6 different clusters on the basis of magnitude of D2 values evaluated by Mahanlanobis D2 analysis.Among forty one genotypes, cluster I was comprising 12 genotypes followed by cluster II with 14 genotypes, cluster III with 5 genotypes, cluster IV with 4 genotypes, cluster V with 5 genotypes and cluster VI with 1 genotype. Inter cluster distance i.e. the maximum intra cluster distance was observed in cluster V (37.17) while the maximum inter cluster distance (117.49) was observed in cluster IV andclusters V. The seed yield is complex character and each character had its own effect for establishing correlation with yield. The path coefficient revealed that the character days to 50% flowering, number of pods per plant, plant height at maturity, dry matter yield per plant and harvest index had positive direct effect on seed yield at both phenotypic and genotypic levels, while days to initiation of flowering, days to maturity, number of primary branches per plant, pod length, hundred seed weight had negative direct effect on seed yield per plant at genotypic and phenotypic levels. It is concluded that IC-614758 followed by AKP-1264 and PGCP-27 are observed as best performance in the genotypes studied. These had highest seed yield per plant and also maximum yield attributing characters. The genotype CPD-31 had maximum seed weight; CP-13 had maximum number of seed per pod, while CP-25 had the maximum number of pods per plant. The genotype Phulevithai had highest protein content, CPD-219 had highest iron content and CPD-220 had minimum plant height. The genotype Konkansadabahar had early maturating. These genotypes can be used as promising genetic material in future breeding program. There was significant diversity reported in present study among all the genotypes.

    (Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli , Dist : Ratnagiri, 2018) WAGHMARE, PANDURANG DILIP; PETHE, U. B.
    The present experiment entitled “Variability and correlation studies in cowpea (Vignaungiculata(L.) Walp)” was undertaken to assess the genetic variability, correlation and path analysis in thirty genotypes of cowpea in randomized block design with two replications at educational and research farm, Department of Agril. Botany, College of Agriculture,Dapoli, Dist. Ratnagiri, Maharashtra during Rabi 2016-2017. The estimates of phenotypic, genotypic and environmental variance revealed that phenotypic variance were higher in magnitude than genotypic variances for all the characters. The magnitude of phenotypic and genotypic variances was closer to each other for majority of the characters this indicating lesser role of environment in the expression of these characters. However plant height, dry matter yield per plant and days to maturity showed comparatively higher estimates of environmental variance indicating the influence of environment on these characters. Title of thesis : Variability and correlation studies in cowpea (Vignaunguiculata (L.) Walp) Name of the student : Mr. PandurangDilipWaghmare Regd. No. : 2488 Degree Discipline : : M. Sc. (Ag.) Genetics and Plant Breeding Name of the Research Guide : Dr. U. B. Pethe Jr. Spice Breeder AICRP on Spices, Dept. of Horticulture, College of Agriculture, Dr. B. S. K. K. V. Dapoli. Year of thesis submission : 2018 In general, phenotypic coefficient of variation (PCV) was higher in magnitude over genotypic coefficient of variation (GCV) for all the characters. Different characters showed varying per cent of coefficient of variation at both genotypic and phenotypic levels. High genotypic and phenotypic coefficient of variation was observed for the characters number of pods per plant followed by seed yield per plant, hundred seed weight and number of seeds per pod, while these were low for the characters days to maturity, days to fifty per cent flowering and days to first flowering. In the present investigation, the genotypic correlation coefficients were higher in magnitude than their phenotypic counterparts for most of the characters. The characters dry matter yield per plant, harvest index, hundred seed weight, number of pods per plant, number of seeds per pod exhibited highly significant positive correlation with seed yield per plant at both phenotypic and genotypic levels. The character, plant height showed significant negative phenotypic correlation with seed yield per plant. The seed yield is complex character and each character had its own effect for establishing correlation with yield. The path coefficient analysis revealed that thecharacter days to fifty per cent flowering, plant height, number of seeds per pod, dry matter yield per plant, hundred seed weight and harvest index had positive direct effect on seed yield per plant, while number of primary branches per plant and days to maturity had negative direct effect on seed yield per plant at genotypic and phenotypic level. It is concluded that genotype PCB-9796 followed by CPD-118 and RC-101 were the promising among all the genotypes studied on the basis of seed yield per plant by considering all yield attributing characters. The genotype PCB-9796 is bold seeded with maximum hundred seed weight, KBC-9 had maximum number of seeds per pod, whileMrugraj had the maximum number of pods per plant. These genotypes can be used as promising genetic material in future breeding program.

    (Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli , Dist : Ratnagiri, 2018-05) DHANSING, ADSUL VISHAL; Mane, A.V.
    A field experiment was conducted at education and research farm, Dept. of Agril. Botany, College of Agriculture, Dapoli during rabi 2017-2018 to study effect of biocontrol agents on physiochemical aspects of Wal (Lablab purpureus L). Different bio control agents were applied through foliar spray at 2st and 4th week after sowing. The experiment laid out in randomized block design with seven treatments randomized inthree replications. The apllied seven treatment VIZ T0 RDF only, T1 Rhizobium treatment, T2 RDF+ T1, T3 Tricoderma viride (4ml/lit)+ T1, T4 Pseudomonas fluorescence (4ml/lit)+ T1, T5 Bacillus subtilis (4ml/lit)+ T1, T6 Paceilomyces lilacinus (4ml/lit)+ T1 respectively. Beside yield and yield attributes data were collected on plant height, number of branches, number of leaves, days to 50% flowering, days to maturity, chlorophyll content, nitrogen content, phenol content, proline content, relative water content, Dry matter accumulation, leaf area, LAI, AGR, RGR, and NAR at the interval of 30, 60, 90 DAS and at physiological maturity. Result indicated that most of the yield and yield determining attributes recorded significant difference due to treatment effects. Among the treatments T6 (Paceilomyces lilacinus) recorded significant difference on yield and yield attribute, morphological, growth, physiological and biochemical parameter. The plant height was increased significantly in treatment T6. The significant increase in leaf dry weight, stem dry weight and total dry weight were observed in treatment T6 (Paceilomyces lilacinus). The number of days required for days to 50% flowering and days to maturity significantly reduced with the application of Paceilomyces lilacinus. Growth parameters viz. leaf area, leaf area index, RGR, AGR, LAI and NAR were significantly lower in control and the application of Paceilomyces lilacinus have been found effective in increasing parameters. The application of biocontrol agent enhanced physiological and biochemical parameters i.e. photosynthesis, stomatal conductance, chlorophyll content, phenol content, nitrogen content and relative water content the effect was more with application of Paceilomyces lilacinus. All biocontrol agent increases the accumulation of phenol but among them Paceilomyces lilacinus is superior rest of treatment. There was no any significant difference in proline accumulation among the treatments. The application of bio control agent enhanced the yield and yield attributing character i.e number of pods, pod yield per plant), Pod yield per plot, seed yield per plot, harvest index and seed yield per plot. The effect was more with application of Paceilomyces lilacinus followed by Pseudomonas fluorescence treatment. Seed yield per plot ranged between 772.45g and 510.17g maximum and minimum value being in T6 and T0 respectively. It shows variation between treatments. Among all treatments T6 (Paceilomyces lilacinus) was significantly superior treatments in all characters.

    STUDIES ON HETEROSIS AND COMBINING ABILITY FOR YIELD AND YIELD ATTRIBUTING TRAITS IN GREEN GRAM (Vigna radiata L. Wilczek) (Accession No. T06464)
    (Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli , Dist : Ratnagiri, 2018-05) BICHUKALE, MAHESH SHAMRAO; Devmore, J. P.
    The present investigation was carried out with a view to study the magnitude of heterosis, combining ability and gene action through Line x Tester analysis including ten parents, including one check and their twenty four F1 in green gram for Rabi 2017-18 conditions. The experimental material was planted in randomized block design with three replications at the research and educational farm, Department of Agriculture Botany, College of Agriculture, Dapoli. The analysis of variance for all the characters revealed that parents were found to be highly significant for all the character studied except branches per plant, pods per cluster and pods per plant indicating presence of considerable amount of genetic variability in the parental material tested. Also, all the yield contributing characters showed highly significant mean square due to hybrids vs parents‟ and 133 hybrids were highly significant for all the characters, Parents vs. hybrids comparison was found to be highly significant for all the characters studied except hundred seed weight indicating presence of heterotic combination. Among the Parents, TARM-2, Ml-2056, TARM-1, and Karjat local were recorded as the best performing parents for grain yield per plant. High heterotic effects were observed for days to 50 per cent flowering, days to maturity, number of branches per plant, number of clusters per plant, number of pods per cluster, number of pods per plant, pod length and grain yield per plant. It was observed from the present study that heterotic response for seed yield per plant was mainly due to high heterotic response observed for number of branches per plant, number of pods per plant, pod length and number of clusters per plant, number of pods per cluster. Combining ability analysis revealed that the mean squares due to general combining ability and specific combining ability were highly significant for almost all the characters indicating importance of both additive as well as non-additive gene effects involved in the expression of all the characters. However, the variances due to general combining ability in general were lower than specific combining ability for days to maturity, plant height, branches per plant, clusters per plant, pods per plant, grains per pod, hundred seed weight and grain yield per plant thus on the basis of ratio of gca and sca results pointing out the preponderance of non-additive gene effects for the characters studied. The general combining ability effects revealed thatML-2333, ML-2056, TARM-1 and Karjat localwere the good general combiner for grain yieldand other yield related traits. The crosses ML-2333 x TARM-1,NVL-641 x TARM-1 andNVL-641 x Karjat local were found to be good 134 in respect of sca effects for yieldrelated characters. This might be due to effect of alleles of combining parents. Out of these best specific cross combinations, majority of the crosses showed high per se performance along with higher heterotic effects and higher sca effects for seed yield per plant indicating more reliability of per se performance. The per se performance of parents were more or less related to their gca effects. On the basis of per se performance, heterosis, combining ability, and gene action of the hybrids viz., ML-2333 x TARM-1, NVL-641 x TARM-1, PUSA-1477 x TARM-1, ML-2056 x TARM-1andML-2056 x Karjat local was found to be the most promising combination for most of the yield contributing traits viz., grain yield per plant (g), number of pod per plant, number of clusters per plant, number of pods per cluster, hundred seed weight (g), plant height, number of pods per plant and pod length (cm).

    DEPARTMENT OF AGRILTURAL BOTANY, COLLEGE OF AGRICULTURE, DAPOLI Title of thesis : “Genetic Variability Studies in F3 Generation of brinjal (Solanum melongena Linn.)” Name of the student: : Mr. Hegade Tushar Balu Regd. No. : ADPM/15/2416 Degree Discipline : : M. Sc. (Ag.) Genetics and Plant Breeding Name of the Research Guide : Dr. S. G. Bhave Director, Extension Education, and Head, Department of Agril. Botany, Dr. B. S. K. K. V., Dapoli, Ratnagiri. Year of thesis submission : May,2017 ABSTRACT An experiment was conducted with thirty genotypes in rabbi season of 2016-17 at research and education farm, Department of Agriculture Botany, College of Agriculture, Dapoli. Observation were recorded on ten characters viz., days to first flowering, day to fifty per cent flowering, plant height (cm ), days to first fruit picking, number of primary branches per plant, number of fruits per plant, fruit length ( cm), fruit diameter ( cm), fruit weight ( g), fruit yield per plant ( g). The estimate, of phenotypic, genotypic and environmental variances revealed that, in general phenotypic variances for all the characters studied were higher than genotypic variances. Phenotypic coefficient of variation was greater than the genotypic coefficient of variation for all the characters for present study. The high phenotypic and genotypic coefficient of variation was 49 observed for number of fruits per plant, fruit length (cm), fruit yield per plant and the moderate phenotypic and genotypic coefficient of variation was observed for plant height (cm), number of primary branches, fruit weight (g), while lowest GCV and PCV was observed for days to first flowering, days to fifty per cent flowering and days to first picking. High heritability with high genetic advance as percentage of mean was observed for fruit yield per plant, number of fruit per plant and fruit weight (g). It indicates additive gene action and made it suitable for direct selection. In general genotypic correlations were higher than phenotypic correlations. The correlation study revealed that the characters viz., plant height, number of fruits per plant and fruit length showed significant positive correlation with fruit yield at phenotypic and genotypic level. While, the character fruit diameter, fruit weight showed highly significant negative correlation with fruit yield at both level. The path coefficient analysis revealed that the characters viz., number of fruit per plant, fruit weight (g) exhibited positive direct effect on fruit yield per plant. While, the character days to first picking, fruit diameter plant height (cm) showed negative direct effect on fruit yield. Path analysis at phenotypic and genotypic level reveals the casual relationship between different characters related to yield. On the basis of path analysis and correlation study for fruit yield, it is concluded that selection on the basis of number of fruits per plant, fruit weight (g), days to first flowering could help in genetic improvement of fruit yield per plant in brinjal under study. The eleven promising pure mutant lines identified for further evaluation (Table No.10). Key words: Genetic variability, Correlation and Path analysis,
