Was carried out at Horticulture Research station (AICRP On Vegetable crops ) ,Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during Kharif , 2018. The Genetic diversity within Bitter gourd germplasm is a key to the future genentic improvement (Hybridization ) programme . In the present study 40 genotypes of Bitter gourd collected from various institutes and different regions of India were replicated twicely & sown in Randomised blocks with standardized net plot size of 5×1.5 mtrs . And general spacing of 1.5×1mtrs in between the rows and plants respectively during Kharif 2018 at Horticulture research station (AICRP On vegetable crops). In this investigation Results of all the 40 genotypes were analyzed for diversity for 16 morphological characters viz. vine length , number of days for first female flower opening, node number at which first female fower open , number of days taken for first fruit harvest, nuber of branches per plant , Duration of crop, Days to 50% flowering , fruit length , fruit diameter, Average fruit weight, number of fruits per vine , fruit yield per vine , fruit yield per hectare , number of seeds per fruit , flesh thickness, Ascorbic acid content using Mahalanobis D2 statistics are illustrated below. Multivariate analysis (D2 statistic) given by Mahalanobis‟s was used to group the 40 bitter gourd genotypes into 6 clusters. A maximum of 32 genotypes entered in cluster I, followed by 4 genotypes in cluster II. The cluster III, IV, V and VI had single genotypes each. The highest intra cluster distance (D2 values) was observed in cluster II (104.02) followed by cluster I (96.08). The Maximum inter cluster distance was observed between cluster II and VI (1620.05) followed by cluster IV and cluster VI (1262.95), cluster II and cluster V (1098.44) and cluster II and cluster III (851.00). This indicates, the genotypes belong to these clusters are more diverse and hence, hybridization between genotypes of respective clusters may improve the yield and quality traits in bitter gourd. The number of genotypes per cluster varied from 1 - 32. This wider genetic variability may be due to the adaptation of these genotypes to specific environmental conditions. Among the 15 characters studied for D2 analysis, ascorbic acid contributed the maximum (37.31%) to the genetic diversity followed by fruit length (15.64%), frui diameter (14.36%), flesh thickness (11.92%), number of seeds per fruit (9.49%) and days to first female flower opening (6.92%). The PCV was higher as compared to GCV for all the characters. This indicates that the environment played a major role in the expression of these traits. The high (> 20%) GCV and PCV were observed for fruit length, average fruit weight, number of seeds per fruit, fruit yield per vine and flesh thickness. It indicates existence of broad genetic base, which would be amenable for further crop improvement. Moderate GCV and PCV (10-20%) was observed for number of branches per vine and fruit diameter which indicates more variability in these characters. The high estimates of heritability (above 60%) coupled with high values of GAM (more than 20%) were observed for characters viz., fruit length, fruit diameter, number of seeds per fruit, flesh thickness, fruit yield per vine, fruit yield per hectare, average fruit weight, vine length and number of branches per vine. This indicates predominance of additive component for these characters and they are more reliable for effective selection to improve the yield of bitter gourd. High heritability (> 60%) coupled with moderate to low values of GAM (< 20%) were obtained for days to first female flower opening and ascorbic acid indicated that prevalence of non-additive components and there can be little response to selection and these traits can be exploited through heterosis breeding. Moderate to low heritability (< 60%) coupled with high GAM (> 20%) were observed for node at which first female flower appears. This indicates the importance of additive gene effects for these traits and there can be better response to selection. Moderate to low heritability (< 60%) with moderate to low values for GAM (< 20%) were observed for duration of crop, days to 50 per cent flowering, days to first fruit picking and number of fruits per vine. These results elucidate prevalence of non-additive components and higher influence of environments on these traits and hence, selection would be ineffective. Fruit yield per vine was highly significantly and positively associated with vine length, number of branches per vine, duration of crop, node at which first female flower appears, days to 50 per cent flowering, days to first fruit picking, fruit length, fruit diameter, average fruit weight, number of seeds per fruit and flesh thickness at phenotypic and genotypic levels. This indicated that direct selection for these characters might be effective and there is a possibility of improving yield per vine through selection based on these traits. The characters viz., fruit length, fruit diameter, duration of crop and average fruit weight are important characters to be accounted for gaining improvement in fruit yield per vine since, these characters had high positive direct and indirect effects on fruit yield per vine. Thus the Maximum inter cluster distance observed between cluster II and cluster IV followed by cluster IV and cluster V and cluster II and V. This indicates, the genotypes belonging to these clusters are more diverse and hence, hybridization between genotypes of respective cluster may improve the yield and quality of bitter gourd. The characters viz., fruit length, average fruit weight, number of seeds per fruit, fruit yield per vine, fruit yield per hectare and flesh thickness were recorded high GCV, PCV, heritability and GAM. Hence, these characters had lot of variability with additive gene actions. Therefore, these traits can be improved by simple selection. Fruit yield per vine was positively and significantly associated with fruit length, fruit diameter, duration of crop and average fruit weight. These characters have to be considered while selecting the genotypes for fruit yield per vine. These characters also recorded high direct effect on fruit yield per vine.ThesisItem Open Access Genetic divergence studies in okra (abelmoschus esculentus (l.) Moench.)(Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, 2017-07-05) Banothu Rambabu; Waskar, D.P.The present investigation was undertaken to estimate the genetic divergence in okra and to carry out yield component analysis through correlation and path analysis. Twenty genotypes were sown in a randomized block design with two replications, during Kharif 2016-2017 at Horticulture Research Station, College of agriculture, VNMKV, Parbhani, Maharashtra. The objective of the experiment was to identify divergent genotypes to use as donor parents in hybridization programmes. The D2 analysis for eighteen characters partitioned the twenty genotypes into five clusters. The maximum genetic divergence was observed between cluster III and V followed by between clusters I and V. The maximum intra cluster distance was shown by cluster IL The characters number of branches per plant, number of fruits per plant, total number of pickings, fruit weight, fruit length and fruit yield per plant contributed greatly towards diversity. The clusters showing high genetic divergence could be effectively utilized in heterosis breeding programme. If a breeding programme is used at improving growth attributes like plant height, then cluster III showing maximum plant height can be utilized in breeding programme. Therefore, a plant breeder may keep in mind the above aspects to obtain superior hybrids and good recombinants. The analysis of variance revealed significant difference for eighteen characters studied suggesting considerable amount of variability exists among 1 the genotypes. Wide range of variability was observed for plant height, number of seeds per fruit, iodine content, and fruit yield per plant indicating the scope for selection of suitable initial breeding material for further improvement. In a true agreement with the GCV and PCV values in the present investigation for most of the characters was noticed, indicating additive genetic variance governing the high heritability (>60%) with high genetic advance as per cent of mean was high (>20%) for plant height, number of branches, days to first flowering, days to 50% flowering, days to first harvest, average fruit weight, number of fruits per plant, number of seeds per fruit, number of pickings, 100 seed weight, crude fibre content, iodine content, iron content and fruit yield per plant. Hence there could be exercised for improvement through selection. From correlation studies it was observed that fruit yield per plant has exhibited highly positive and significant association with plant height, number of branches per plant, inter nodal length, days to last harvest, fruit length, fruit girth, fruit weight, number of fruits per plant, number of seeds per fruit, 100 seed weight and number of pickings, crude fibre content, iron content and iodine content. Therefore, it is emphasized to lay attention on these traits in crop improvement programme of okra in future. The results on path analysis indicated that the characters which exhibited maximum positive direct effect on fruit yield per plant and positive associations like Plant height, Number of branches per plant, inter nodal length, days to first flowering, days to first harvest, fruit length, fruit girth, average fruit weight, number of seeds per fruit, 100 seeds weight, total number of picking, crude fibre content, iodine content and iron content would be more effective to bring improvement of yield and to evolve superior high yielding genotypes in okra. On the basis of mean performance of the genotypes among traits studied, IC-43743 from cluster III, PBNOK-2 from cluster V and IC-22237 from cluster IL were found to be best in almost all the attributes i.e. , growth, earliness, fruit traits, and yield. Hence, for exploitation of fruit quality four genotypes i.e., IC-10533, PBNOK-2, PBNOK-5 and EC-755648 were found to be best for qualitative characters. So, these genotypes were considered the best genotypes and would be used as parental source in future breeding programmes.ThesisItem Open Access Genetic diversity in brinjal(Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, 2018-05-30) Gurve, Vaibhao Ramesh; Waskar, D.P.The present investigation was undertaken to estimate the genetic divergence in brinjal and to carry out yield component analysis through correlation and path analysis. Twenty genotypes were sown in a randomized block design with two replications, during kharif 2017-2018 at Horticulture Research Scheme, College of agriculture, VNMKV, Parbhani, Maharashtra. The objective of the experiment was to identify divergent genotypes to use as donor parents in hybridization programmes. The D2 analysis was carried out for twenty fivecharacters which partitioned the twenty genotypes into three clusters. The maximum genetic divergence was observed between clusters II and III. The maximum intra cluster distance was shown by cluster II. The characters viz.,fruit yield per hectare,fruit yield per plot, number of fruit per plant, average fruit weight, fruit length, fruit diameter, number of branches per plant, days to 50% flowering and plant spread (N-S) were contributed greatly towards diversity. The clusters showed high genetic divergence that could be effectively utilized in heterosis breeding programme. If a breeding programme is used at improving nutritional characters, then cluster II showing maximum ascorbic acid that can be utilized in breeding programme. Therefore, a plant breeder may keep in mind the above aspects to obtain superior hybrids and good recombinants. The analysis of variance revealed significant difference for twenty five characters studied suggesting considerable amount of variability exists among the genotypes. Wide range of variability was observed for plant height, plant spread, fruit setting percent, number of fruits per plant, average fruit weight, total phenolic content, fruit yield per plant, fruit yield per plot and fruit yield per hectare indicating the scope for selection of suitable initial breeding material for further improvement. GA as percent of mean, GCV and PCV values are on par with each other for most of the characters that the influence of the environment on the traits. The values observed are not confounding with the environment. It is a true to the reflection of the homeostasis effect or buffer reaction of the gene. Thus, the true reflection of the trait is exhibited. In a true agreement with the GCV and PCV values in the present investigation for the 25 characters was noticed, indicating additive genetic variance governing the high heritability with genetic advance as percent of mean. Thus a breeder can employ a simple selection process which will be a rewarding one to improve the characters viz.,average fruit weight, fruit length, number of fruit per plant, shoot and fruit borer infestation, ascorbic acid content, fruit yield per plant, fruit yield per plot, fruit yield per hectare, fruit diameter, flavonoid content and number of fruit per cluster. From correlation studies it was observed that fruit yield per plant has exhibited highly significant positive association withplant height, number of branches per plant, plant spread, number of fruit per plant, fruit length, fruit diameter, fruit pedicel length, ascorbic acid and fruit yield per hectare. Path analysis revealed that maximum positive direct effect on fruit yield per plant was exhibited by number of branches per plant, plant spread (N-S), days to 50% flowering, number of fruit per plant, fruit pedicel length and ascorbic acid. Therefore, it is emphasized to lay attention on these traits like number of fruits per plant and number of branches per plant in crop improvement programme of brinjal in future. On the basis of the mean performance of the genotypes among traits studied, the following were identified as promising lines for further crop improvement in brinjalviz.,VR-2, Aussay, UtkalJyoti, PBNB-6, BH-2, JKGEH-6012, PBNB-5, PBNB-9, KashiTaru, UtkalKeshari and DMU-1.ThesisItem Open Access Genetic diversity in chilli (capsicum annum L.)(Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, 2018-08-24) Langute, Hanmant Nana; Waskar, D.P.The present investigation was undertaken to estimate the genetic divergence in Chilli and to carry out yield component analysis through correlation and path analysis.

The packed bottle gourd fruits Cv. Samrat were stored at room temperature (26.16 - 29.80 C ; 53.96 - 68.35% R.H.) and in low cost, low energy input cool chamber (20.16 - 21.18 C; 90.25 - 94.50% R.H.) in August 1994. There was an increase followed by subsequent decrease in TSS, reducing sugar and total sugar content with corresponding decrease in acidityupon prolonged storage of bottle gourd fruits under both the storage conditions irriespective of packaging treatments.ThesisItem Open Access Studies on extending the shelf life of fig(ficus carica L) fruits cvs.Poona figond Dinkar(Mahatma Phule Krishi Vidyapeeth, Rahuri, 2005) Gore, S.P; Waskar, D.P.; 635/GANThesisItem Open Access Studies on Extending the Shelf life of Pomegranate (Punica granatum L.) Fruit Cv. Ganesh(Mahatma Phule Krishi Vidyapeeth, Rahuri., 1997) Khedkar Pandit B.; Waskar, D.P.The present investigation entitled "Studies on Extending the Shelf life of Pomegranate (Punica granatum L.) Fruit Cv. Ganesh" with six postharvest treatments and two storage conditions was conducted in two sets of experiments with three replications in Factorial Completely Randomized Design. The treated fruits of pomegranate Cv. Ganesh were stored at room temperature (22.7 to 24.36 C : 52.0 to 82 % R.H.) and in cool store (8 C : 90 to 95% R.H.) There was an increase followed by subseqent decrease in TSS, reducing sugars, total sugars and specific gravity with corresponding decrease in acidity and juice content upon prolonged storage of pomegranate fruits under both the storage conditions irrespective of postharvest treatments.
