ThesisItem Open Access Effect Of Pruning And Ethrel Appication On Vegitative Growth And Fruit Yield Of Cucumber Under Greenhouse Condition(Chaudhary Charan Singh Haryana Agricultural University; Hisar, 2005) Suthar, Mange Ram; Mangal,J. L.ThesisItem Open Access Storage behaviour of potato as affected by time of haulm killing and harvesting(CCSHAU, 2005) Suhag, Munish; Nehra, B.K.The investigation “Storage behaviour of potato as affected by time of haulm killing and harvesting was conducted at vegetable research farm and laboratories of CCS HAU Hisar during 2001-02. The study was conducted under two sets. Ist set of samples was used for studies under ambient storage and IInd set was used for cold storage studies. The investigation consisted of eighteen combination of nine treatment of haulm killing at 90, 100 and 110 days after planting and field curing for 0, 10 and 20 days after haulm killing in each treatment with two varieties (Kufri Badshah and Kufri Sutlej). Total tuber yield increased from 246.9 q/ha to 277.4 q/ha in Kufri Badshah and from 216.3 to 248.3 q/ha in Kufri Sutlej with increase in crop duration from 90 to 110 days after planting. The mean weight loss under ambient condition decreased from 11.3% where crop duration was 90 days and no field curing was done to 7.4% where crop duration was 110 days and field curing was for 20 days in Kufri Badshah. Figures for these two treatment in Kufri Sutlej were 14.6 and 11.9% respectively. The mean weight loss increased from 0.9 to 27.5% as the storage period prolonged from 10 to 105 days. Similarly during cold storage mean weight loss decreased as crop duration and field curing increased. After cold storage also weight loss decreased with increase in crop duration and field curing. But after cold storage the mean weight loss increased from 10.1 to 23.5% within one month. Sprouting percentage was decreased from 54.0 to 47.6% in Kufri Badshah and 55.1 to 50.3% in Kufri Sutlej as the crop duration increased from 90 to 110 days and field curing was allowed for 20 days. Sprouting percentage increased from 22.5 to 76.1% during storage from 60 to 150 days. As the crop duration and field curing increased mean dry matter content also increased. It ranged from 16.5 to 18.1% in Kufri Badshah and 15.3 to 17.9% in Kufri Sutlej with increase in crop duration from 90 to 110 days and field curing was allowed from 0 to 20 days. The dry matter content also increased as the storage period increased. It ranged from 16.4 to 17.3% during storage of 30 to 150 days. Sugar content slightly increased with increase in crop duration and also with field curing, however there was no set pattern. During storage sugar content increased for the first 60 days and lateron it decreased.ThesisItem Open Access Effect Of Method And Time Of Sowing, Fertility Level, Stage Of Umbel Picking On Growth And Yield Of Fennel(Chaudhary Charan Singh Haryana Agricultural University; Hisar, 2005) Hans Raj; Thakral, K.K.ThesisItem Open Access Studies On Post Harvest Behaviour Of Kharif Onion (Allium Cepa L.)(Chaudhary Charan Singh Haryana Agricultural University; Hisar, 2005) Sharma, Meenakshi; Sewa LalThesisItem Open Access Effect Of Plant Density, Steckling Size, Pruning And Growth Regulators On Seed Crop Of Carrot ( Daucus Carota L.)(Chaudhary Charan Singh Haryana Agricultural University; Hisar, 2005) Kuldeep Kumar; Narendra SinghThesisItem Open Access Effect Of Late Plantings And Fertilizers Doses On Growth And Yield Attributes Of Potato (Solanum Tuberosum L.)(Chaudhary Charan Singh Haryana Agricultural University; Hisar, 2005) Sandhu, Amarjeet Singh; Bhutani, R.D.ThesisItem Open Access Response Of Potato, Onion And Guar Grown In Sequence To Organic Manure And Biofertilizers(Chaudhary Charan Singh Haryana Agricultural University; Hisar, 2005) Makhan Lal; Khurana, S.C.ThesisItem Open Access Diallel Analysis in bitter gourd (Momordica charantia L.)(CCSHAU, 2005) Gupta, Vishal; Nand KishoreThe present investigation was undertaken to study correlation, path, combining ability, heterosis and gene effects using 9x9 half diallel set for sixteen characters in Randomized Block Design with three replications at the Vegetable Research Farm and Laboratory, CCS Haryana Agricultural University, Hisar during spring-summer season, 2003. Analysis of variance indicated sufficient variability among parents and their hybrids. Significant positive correlations were observed for fruit length with number of fruits per plant, average fruit weight and total fruit yield per vine. Days to first female flower showed the highest direct contribution followed by number of fruits per plant and average fruit 9 weight towards yield while days to first fruit harvest exhibited its highest indirect contribution via days to first female flower followed by fruit length and fruit diameter via days to first fruit harvest. IC-44410 was the best general combiner for average fruit weight, number of fruits and total fruit yield per plant whereas, BL-237 for chlorophyll ‘b’ and ascorbic acid content. IC-44410 x IC-68316, Pusa Vishesh x BL-237 and IC-44410 x BL-237 were rated as the best crosses on the basis of their sca, heterotic effects and per se performance for yield and for one or other yield attributes. Component analysis revealed that all the characters showed non-additive type of gene effects. Medium heritability (ns) was recorded for node to first female flower, fruit diameter, average fruit weight and TSS. Four dominant genes were present for every recessive gene in parents for days to first fruit harvest and average fruit weight. The comparative evaluation of combining ability, component analysis and mean degree of dominance predicted that characters viz., fruit length, number of fruits per plant, average fruit weight, total fruit yield per plant, chlorophyll ‘a’, chlorophyll ‘b’, total chlorophyll, carotenoid, ascorbic acid and dry matter contents showed non-additive gene effects and hence these characters can be improved through hybridization.ThesisItem Open Access Production of hybrid seed using GA3 and genetic markers in tomato (Lycopersicon esculentum Mill.)(CCSHAU, 2005) Ram Narayan Singh; Batra, VinodThe present study was conducted at CCS HAU, Hisar for production of hybrid seeds using different concentration of GA3 and genetic markers. Five lines, i.e., selection-21 (potato leaf type), CLN-2366A, CLN-2116D9F1-180-31-9-40, CLN-2-16-8-2-176 and EC-339357 (anthocyaninless type) were used as female parent. Three lines Hisar Arun, H-86 and VFN-8 were used as male parent are cut leaf type and anthocyanin present on the hypocotyl. Cut leaf type is dominant over potato leaf type and anthocyanin type is dominant over anthocyaninless type. GA3 was sprayed 40 and 60 days after transplanting as whole plant spray @ 50 and 100 ppm. Fifteen different crosses were made and observations for per cent fruit set, number of seeds per fruit, seed germination, seed vigour index I and II and percent hybrids plants. Confirmation of markers was done at early stage of seedling in the green house. Among all the treatments, the GA3 50 ppm was found best for fruit setting and seed germination. However, for the number of seeds per fruit and seed vigour index I and II, hand emasculation and hand pollination was at par with GA3 50 ppm. The per cent hybrid plants identified at seedling stage were non significant under different treatments. However, cost of producing hybrid seed was 38% less in GA3 50 ppm as compared to hand emasculation and hand pollination. The futuristic approach of hybrid seed production using different concentrations of GA3 on different genetic markers and ancillary investigations have been suggested.
