Development of new promising varieties of faba bean through traditional pedigree method for commercial cultivation in plain zone of India

A long term experiment was carried out in MAP Section, Department of Genetics & Plant Breeding,  CCS Haryana Agricultural University, Hisar from 2005-06 to 2018-19 on identification of elite genotypes from germplasm and their utilization in the development of high yielding variety through hybridization followed by traditional pedigree method to obtain desirable transgressive segregants in Faba bean. In the present investigation a number of germplasm lines were screened for seed yield and other related traits including national check Vikrant during 2005-06 under AICRN in augmented block design. As a result, ten elite genotypes identified i.e. EC117755, EC117799, EC248710, EC329675, HB123, HB180, HB430, HB204, HB 430, HB 502, HB 503 & one check variety, Vikrant. By using these elite genotypes, a number of F1 hybrids were made during 2005-06 and F2 to F6 generations were evaluated to identify the superior progenies during 2007-08 to 2011-12. After a long process of evaluation, rejection and selection, 20 superior transgressive segregant homozygous progenies were identified to make new entries. Later on, during 2012-2013, the superior entries (viz. HB12-1, HB12-5, HB12-8, HB12-9, HB12-11, HB12-12, HB12-13, HB12-14, HB12-15, HB12-26, HB12-28, HB12-29, HB12-30, HB12-31, HB12-34, HB12-36, HB12-37,HB12-38, HB12-39 and HB12-42) were evaluated at Hisar centre against Vikrant and found promising. Therefore, all these 20 genotypes were evaluated in SST during 2013-14, LST during 2014-15 and FYT during 2015-16. On the basis of above results, only five genotypes viz. HB12-8 (47.77q/ha), HB12-42 (47.70q/ha), HB12-15 (46.70q/ha), HB12-34 (46.14q/ha) and HB12-37 (45. 31q/ha) were found promising. These were further evaluated in multi-location trials at seven locations (i.e. Ambikpur, Delhi, Faizabad, Faridkot, Hisar, Ludhiana & Ranchi) for seed yield, quality and resistance against insect pest & disease in IVT and AVT during 2016-17 & 2017-18, respectively. Out of these, HB12-34 exhibited yield superiority over national checks,Vikrant and HFB-1 and free from insect pest and disease as well as low in vicine-covicine and high in protein content. Therefore, HB12-34 may be recommended for commercial cultivation in plain zone at national level

Effect of Crop Establishment Methods and Nitrogen Levels on Growth, Yield Attributes and Yield of Coarse Rice

A field experiment was conducted during kharif 2020 at farm of College of Agriculture, Kaul (Kaithal) of CCS Haryana Agricultural University, Hisar to investigate the response of short duration non-scented rice variety HKR-48 to nitrogen under two different methods of crop establishment. The experiment was laid out in RBD factorial design consisting of two establishment methods i.e. direct seeded (DSR) and transplanted (TPR) as main plot treatments and six different levels of nitrogen (0, 30, 60, 90, 120 and 150 kg/ha) in sub- plots with three replications. The experiment showed that plants grown under the DSR method had greater height and tiller production at all growth stages but experienced higher tiller mortality later on. DSR also resulted in higher early-stage dry matter accumulation compared to TPR, but there was no significant difference at later stages or at harvest. Although the number of effective tillers did not significantly differ between DSR and TPR, DSR had 16% more grains per panicle with the same test weight. However, the transplanted crop had a significantly higher grain yield (11.9%) compared to the direct-seeded crop. Increasing nitrogen dosage up to 120 kg N/ha positively influenced growth parameters and yield-contributing characters. There was no significant difference between 120 kg N/ha and 150 kg N/ha in respect of growth indicators. Grain yield was significantly enhanced with increased nitrogen dosage, but the difference between 120 kg N/ha and 150 kg N/ha was not significant

Development of new promising varieties of faba bean through traditional pedigree method for commercial cultivation in plain zone of India

895-904A long term experiment was carried out in MAP Section (GPB), CCS HAU, Hisar from 2005-2019, beginning with evaluation of germplasm identification of superior parental lines, hybridization and selections as per the traditional pedigree method for development of high yielding varieties of Faba bean. In the present investigation, a number of germplasm lines were screened for seed yield and other related traits including a national check Vikrant during 2004-05. As a result, ten elite genotypes were identified. These selected genotypes were inter-mated to produce a series of F1 hybrids followed by raising of F2 to F6 progenies for selection of superior recombinants during 2007-08 to 2011-12. This rigorous evaluation and selection process resulted in identification of 20 superior transgressive segregant progenies which could be used as new entries. During 2012-2013, these superior entries were evaluated at Hisar center against Vikrant and were found to be promising. Consequently, these 20 genotypes were evaluated in Small Scale Trial during 2013-14, Large Scale Trial during 2014-15 and Final Yield Trial during 2015-16. On the basis of the above evaluations, five genotypes i.e., HB12-8 (47.77 q/ha), HB12-42 (47.70 q/ha), HB12-15 (46.70 q/ha), HB12-34 (46.14 q/ha) and HB12-37 (45.31 q/ha) were found to be promising. These were further evaluated in multi-location trials for seed yield, quality and resistance against insect pest and disease in IVT and AVT during 2016-17 and 2017-18, respectively. Out of these, HB 12-8 and HB12-34 exhibited yield superiority over national checks, Vikrant and HFB-1 and free from insect pest and disease as well as low vicine-convicine and high protein content. Therefore, HB 12-8 and HB 12-34 may be recommended for commercial cultivation in plain zone at national level
