ThesisItem Open Access Studies on Anthracnose [Colletotrichum capsici (Sydow) Butler and Bisby] of Chilli (Capsicum annuum L.) and its Management(Agriculture University, Jodhpur, 2020-10-08) Vijay Pal; Verma, J.R.; Ram, Dama; Singh, L.N.Chilli (Capsicum annuum L.), belonging to the family Solanaceae is an important spice and vegetable crop because of its massive consumption worldwide. Chilli is native of Tropical America (Brazil) and has been cultivated throughout the world including the tropics, subtropics and temperate regions. Chilli production is continuously attacked by several diseases which drastically reduces the quality and yield of fruit resulting in low returns to farmers. Among all, Anthracnose caused by Colletotrichum capsici (Sydow) Butler and Bisby is one of the most important diseases, causing considerable damage, inflicting severe quantitative and qualitative losses. The disease starting from the field may be continuing even after the fruits have been harvested and kept for drying and storage. The disease is prevalent in almost all major chilli growing areas and it is reported to cause 25–48 % loss in different parts of India. The detailed studies on various aspects were carried out in the present study. A survey conducted for anthracnose disease incidence in different tehsils of Jodhpur district of Rajasthan showed that Tiwari recorded highest anthracnose disease incidence (22.02 %) followed by Bhopalgarh (19.33 %), Bawari (17.26 %), Osian (15.04 %) and least anthracnose incidence was recorded in Bilara (12.94 %). The freshly infected chilli plants showing typical anthracnose symptoms were collected from the farmer’s field and were subjected to isolation by following standard tissue isolation method and revealed the association of Colletotrichum sp. after studying the cultural and morphological characters of the fungus and the pathogenicity was proved by following Koch’s Postulates. The pure culture obtained was sent for identification to Indian Type Culture Collection (I.T.C.C.), I.A.R.I., New Delhi – 110 012 and was identified as Colletotrichum capsici (I.D. No. 11,342.20). Ten chilli cultivars were screened and none of the cultivars showed immune, resistant and highly resistant reaction under field condition. Among the fungicides screened in vitro, complete mycelial growth inhibition of C. capsici was observed in Tebuconazole 50 % + Trifloxystrobin 25 %. The lowest anthracnose severity was observed in spray with Trifloxystrobin 25 % + Tebuconazole 50 % at 1.5 ml/lit (11.55 %) under field conditions.ThesisItem Open Access Effect of Staggered Sowing and Spacing on Growth, Yield and Quality of Carrot (Daucus carota L.) Varieties in Arid Region of Rajasthan(Agriculture University, Jodhpur, 2019-05-28) Somveer; Choudhary, Santosh; Moond, S.K.; Raiger, P.R.A field experiment was conducted at College of Agriculture, Mandor, Jodhpur during the Kharif season of 2018, to find out the suitable variety and its optimum sowing time and spacing for higher yield, quality and net returns of carrot in western Rajasthan. The treatments comprising two varieties (‘Pusa Rudhira’ and ‘Pusa Vrishti’), three spacing (20 cm × 10 cm, 30 cm × 10 cm and 30 cm × 20 cm) and four dates of sowing (10th August, 25th August, 10th September and 25th September) allocated in Factorial Randomized Block Design with three replications. Experiment results revealed that variety ‘Pusa Vrishti’ recorded significantly higher growth parameters while ‘Pusa Rudhira’ recorded significantly higher yield parameters, root yield (23.8 t ha-1), quality parameters and net returns (Rs. 2,55,491) with lesser days to marketable maturity (73.9). Among different spacing, significantly higher growth and yield parameters were observed in widest spacing (30 cm × 20 cm). However, root yield (24.5 t ha-1) and net returns (Rs.2,26,604) were recorded highest in S1 (20 cm × 10 cm). The 25th September sowing recorded significantly highest growth parameters, yield parameters, yield (25.8 t ha-1) and quality parameters besides being earliness in term of maturity (73.7 days). However, the highest net returns (Rs. 3,09,028) and B:C ratio (4.33) were recorded in 10th August sowing. The combination of ‘Pusa Vrishti’ sown on 25th September, recorded highest plant height at 60 DAS (39.3 cm) and fresh weight of aerial part (101.9 g) whereas, ‘Pusa Rudhira’ sown on 25th September combination recorded significantly higher values of fresh weight of root (139.4 g), root yield (11.1 kg plot-1) and root yield (25.8 t ha-1). Hence, variety ‘Pusa Rudhira’ sown in closer spacing of 20 cm × 10 cm spacing under staggered sowing is found to be superior in terms of yield, quality, earliness and net returns in the arid regions of Rajasthan.ThesisItem Open Access Effect of Spacing and Training Method on Growth and Yield of Off-season Ridge Gourd (Luffa acutangula L.)

The experiment was laid out in Randomized Block Design with three replications during Kharif 2019 on 20 different genotype of round gourd including two check cultivars, to estimate the extent of genetic variability, heritability, genetic advance, correlation among the yield and other attributing traits, direct and indirect effect of yield contributing traits through path coefficient analysis and genetic divergence through D2 statistics. Analysis of variance (ANOVA) exhibited significant differences for all the studied characters suggesting the presence of great inherent genetic variation amongt the genotypes. The phenotypic coefficients of variation were slightly higher than the respective genotypic coefficients of variation for all the characters under study. High estimates of heritability were noted for almost all the traits except days taken to 50% female flowering, leaf area and days to anthesis of first female flower. High heritability and high genetic advance as per cent of mean were observed for the traits of main vine length at harvest, number of marketable fruits per plant, fruit yield per plant, fruit yield per hectare, fruit yield per plot, node on which first male flower appeared, fruit diameter, shelf life and rind thickness, suggesting additive gene action for expression of these characters. Hence, these characters may prove effective for selection to improve fruit yield per plant in round gourd. Correlation studies among the characters revealed that fruit yield per plant had significant positive association with the characters like number of leaves par plant, main vine length at harvest, internodal length, leaf area, number of marketable fruits, fruit diameter, fruit weight, rind thickness and shelf life both at phenotypic and genotypic levels. Path coefficient analysis of various quantitative characters indicated that main vine length at harvest, internodal length, days to anthesis of first female flower, days taken to 50% female flowering, number of marketable fruits per plant, fruit diameter, fruit weight and rind thickness exhibited positive direct effect on fruit yield per plant. Based on the relative magnitude of D2 values, Tocher’s method resulted in formation of three clusters. Out of the three clusters, cluster I was the largest comprising of fifteen genotypes followed by II with four genotypes while the cluster III was monogenotypic, suggesting the existence of high degree of heterogeneity between the genotypes. The trait of fruit shelf life contributed the maximum towards genetic divergence. The highest intra-cluster distance was recorded in the cluster II, while the inter-cluster distance was the highest between cluster I and II, followed by cluster II and III, indicating that superior recombinants could be obtained by mating between genotypes of these clusters.ThesisItem Open Access Performance and Genetic Variability Studies in Okra [Abelmoschus esculentus (L.) Moench](Agriculture University, Jodhpur, 2020-07-16) Meena, Manish Kumar; Moond, S.K.; Choudhary, Santosh; Raiger, P.R.An experiment entitled “Performance and genetic variability studies in okra (Abelmoschus esculentus (L.) Moench)” was carried out during August 2019 to November 2019 at the Instructional Farm, College of Agriculture, Jodhpur (Rajasthan). The experiment comprised of 12 varieties and hybrids of okra viz. „P-8‟, „Pusa Bhindi-5‟, „Samrat F1 Hybrid‟, „Punjab Suhawani‟, „Arka Nikita‟, „Shakshi F1 Hybrid‟, „Palam Komal‟, „Kashi Kranti‟, „Shakti F1 Hybrid‟, „Arka Anamika‟, „Kashi Pragati‟ and „Laxmi F1 Hybrid‟ and was laid out in Randomized Block Design with three replications. Significant differences were found amongst the varieties and hybrids of okra for the studied characters. The „Arka Anamika‟ recorded the maximum number of branches per plant (2.80), stem diameter (17.10 mm), number of leaves per plant (69.06), number of fruit per plant (25.80), fruit yield per plant (369.78), fruit yield per plot (4.95 kg) and estimated fruit yield per hectare (122.23 q). The „Palam Komal‟ recorded the maximum plant height (139.73 cm) and numbers of nodes on main stem (30.80) while „Laxmi F1 Hybrid‟ produced the largest leaves (156.86 cm2 ). The earliest first flower anthesis (39.67 DAS) and 50% flowering (39.33 DAS) and first picking (45.40 DAS) were recorded in „Kashi Pragati‟, whereas the maximum fruit length was recorded in „Pusa Bhindi-5‟ (12.36 cm). The „Samrat F1 Hybrid‟ recorded the maximum fruit diameter (16.02 mm) and fruit weight (12.99 g) while the longest shelf life of fruit was obtained in „Kashi Kranti‟ (4.47 Days). Fruits of all the varieties and hybrids were dark green in colour with hairy appearance and five ridges except „Arka Anamika‟ which produced green colour fruits. Analysis of variance exhibited significant differences for all the characters which shoed the presence of abundant inherent genetic variation among the genotypes. The phenotypic coefficients of variation were higher than the respective genotypic coefficients of variation for all the characters under study. High estimates of heritability were observed for leaf area followed by days taken to first anthesis, fruit yield per hectare, fruit yield per plot, stem diameter, days taken to first picking, shelf life of fruit, fruit yield per plant, days taken to 50% flowering and number of fruits per plant. Genetic advance as percent of mean (genetic gain) ranged from 29.44 % for yield per hectare to 5.78 % for fruit length. High genetic advance was recorded for fruit yield per plant, fruit yield per hectare and leaf area.ThesisItem Open Access Evaluation of Sweet Pepper (Capsicum annum L. Grossum Sendt.) Genotypes Under Modified Net House(Agriculture University, Jodhpur, 2020-07-16) Meena, Mamraj; Choudhary, Santosh; Moond, S.K.; Ram, DamaA field experiment entitled “Evaluation of Sweet Pepper (Capsicum annum L. Grossum Sendt.) Genotypes under Modified Net House” was carried out during Rabi, 2019-20 at College of Agriculture, Jodhpur (Rajasthan). The experiment was laid out in Randomized Block Design with 20 genotypes and three replications to identify superior genotypes in terms of growth, yield, quality and economics. The results on growth parameters reavealed that genotype „Pusa Deepti‟ recorded highest plant height and number of leaves per plant at 30 DAT (35.8cm and 14.5, respectively), 60 DAT (49.3cm and 53.0, respectively), 90 DAT (71.4cm and 71.3, respectively) and 120 DAT (77.4cm and 77.4, respectively). Whereas, „Pusa Deepti‟ also recorded maximum number of branches per plant at 60 DAT (7.10), 90 DAT (17.30) and 120 DAT (23.10). The maximum stem diameter at harvest was found in „Pusa Deepti‟ (17.3mm). Genotype „Pusa Deepti‟ recorded the maximum fruit length (9.74cm) and number of fruits per plant (19.53) whereas, „Orobelle‟ recorded the maximum fruit diameter (6.00cm). The genotype „Indra‟ was observed with earliest 50% flowering (68.0 days), maximum fruit weight (75.13g), fruit yield per plant (1.345kg), fruit yield per 1000m2 (48.8q) and pericarp thickness (0.60cm). whereas, „Orobelle‟ recorded the highest crop duration (221 days). The maximum number of locules per fruit (4.80) was found in „Ganga‟. In terms of quality parameters, the genotype „Arka Gaurav‟ recorded maximum ascorbic acid (168.6mg/100g) and total soluble solids content (7.53%)‟. The genotype „Indra‟ was observed with maximum shelf-life (8.6 days). The „Indra‟ was identified as remunerative genotype exhibiting highest net returns (`1,04,666/-) and B:C ratio (2.51) per 1000 m2 area. Hence, considering the highest fruit yield genotype „Indra‟ was found to be economically remunerative option for growing sweet pepper under modified net house to improve the socio economic and nutritional status of farmers under western Rajasthan conditions.ThesisItem Open Access Genetic Variability, Character Association and Path Analysis Study in Sweet Potato [Ipomoea batatas (L.) Lam.](Agriculture University, Jodhpur, 2020-07-16) Devkaran; Choudhary, Santosh; Moond, S.K.; Raiger, P.R.A field experiment on “Genetic Variability, Character Association and Path Analysis Study in Sweet Potato [Ipomoea batatas (L.) Lam.]” was carried out during Kharif, 2019 at Agricultural Research Station, Mandor-Jodhpur (Rajasthan). The experiment was laid out in Randomized Block Design with 16 genotypes and three replications to estimate the extent of genetic variability, heritability, genetic advance, the correlation between yield and other characters, the direct and indirect effect of yield contributing traits through path analysis. Analysis of variance exhibited significant differences for all the characters suggested the presence of great inherent genetic variations among the genotypes. The phenotypic coefficient of variation was slightly higher than the respective genotypic coefficient of variation for all the characters under study. High estimates of heritability and genetic advance as per cent of mean were observed for the characters viz., β-carotene followed by marketable tuber yield per ha, tuber yield per plot, tuber length, TSS, number of marketable tuber per plot, tuber yield per ha, tuber yield per plant, leaf width, tuber diameter, fresh weight of tuber, inter-nodal length, starch content, leaf length and vine length. Moderate heritability was observed for number of tubers per plant and number of marketable tubers plant. Correlation studies among the characters studied revealed that tuber yield per plant has a strong positive significant association with characters like the fresh weight of tuber, number of tuber per plant, starch content, tuber diameter, leaf width, leaf length, inter-nodal length, vine length and tuber length. Path coefficient analysis of various quantitative characters indicated that fresh weight of tuber, number of tuber per plant, tuber length, leaf width, leaf length and tuber diameter exhibited a positive direct effect on tuber yield per plant while, vine length and inter-nodal length exhibited the maximum negative direct effect on tuber yield per plant.ThesisItem Open Access Heterosis and Combining Ability Studies in Sesame (Sesamum indicum L.)(Agriculture University, Jodhpur, 2019-07-01) Sirohi, Sushila; Kumhar, S. R.; Choudhary, B.R.; Ram, MoolaAn experiment entitled “Heterosis and combining ability studies in sesame (Sesamum indicum L.)” was carried out during kharif season of 2018 at research farm of Agricultural Research Station, Mandor, Jodhpur. The experiment comprised of twelve parents, their twenty seven crosses and one check, was shown in randomized block design with three replications. The analysis of variance for all the characters revealed that genotypes, parents and hybrids showed significant differences for most of characters expect oil content for parents indicating the presence of sufficient variability in the study material. On the basis per se performance, parents viz., RT-54, RT-103, RT-371 and RT-372 were found promising and crosses viz., RT-351 × TKG-22, RT-351 × RT-377 and RT-54 × TKG-22 were revealed better performance for seed yield per plant. Cross, RT-351 × TKG-22 depicted the highest heterosis, heterobeltiosis and standard heterosis. In combining ability analysis, the extent of GCA variance was lower than SCA variance for most of the characters demonstrating the predominance of non additive gene action except oil content. Based on gca effects, TKG-22, GT-10 and RT-372 were good general combiner for seed yield and some of the component characters. Crosses, RT-351 × TKG-22 and RT-54 × RT-372 were most promising hybrids for seed yield and these crosses involved average × good and average × average parents and could be exploited for heterosis breeding or to produce for desirable segregants for sesame crop improvement.
