Public ISBD in Proceedings of the 27th National Summer Crops Workshop, held at Rampur, Chitawan, 18-20 April 2013, Vol. I / Giri, Y.P.     Title : Enhancing the productivity of mungbean through the breeding improvement in rainy and spring season in rice and maize based cropping system Material Type: printed text Authors: Rajendra Darai ; Surendra Yadav ; Gun Bahadur Gurung ; Nawa Raj Acharya ; Santosh Raj Tripathi, Author Pagination: 58-67 p. Languages : English (eng) Keywords: mungbean  ;  genotypes  varietal  improvement  disease  resitant  synchronous Abstract: The major constraints and challenges in mungbean research and development are susceptibility to MYMV, insect pests, small sized seeds, non-synchronous mahtrity and low yield. Considering the fact, a field experiments on varietal improvement of mnngbean received the genetic materials from A VRDC and local landraces were carried out at Rampur, Nawalpill and Nepa1gunj. In observation nursery (OBN), VC 6153 (B-19) [568 kg_ha] , VC 6173 (B-33) [529 kg_ha] and VC 6173 C [526 kg_ha] were the best performing mnngbean genotypes over the years 20 l 0-20 II and these lines will be selected for yield advance trial. In coordinated varietal trial (CVT), the genotypes Bari mung(575 kg/ha) and VC6153B-20G(572 kg/ha) were the good yielder than the check Pratikcha(477 kglha) in maize based cropping system. Mw1gbean cultivars named Pratikcha(767 kglha), Saptari local(750 kg/ha), VC6153B-20G(715 kg/ha), VC 3960A-88(713 kg/ha), VC 6173B-6(707 kglha) and Bari mung (700 kg/ha) were the best performers in rice-wheat-nmngbean cropping system and significantly differed among the tested lines over the years(2010-2011) and across the locations(Nepalgunj and Parwan ipur). However the mungbean grain yield of the year 20 II was observed incredibly low due to the soil moisture stress during the cropping season as a consequence affected to the mean yield performances. In pre-release varietal trial, genotype BARJ mung ( 1177 kg/ha) and HUM-16(1 052 kg/ha) were the best perfonning genotypes than the check Pratikcha(l021 kg/ha). It had also earlier matllfity with the highest number of pods bearing capacity. Therefore seed of these lines should be increased at station and farm level so as to help in varietal promotion and scaling up into the targeted areas Link for e-copy: http://elibrary.narc.gov.np/?r=861 in Proceedings of the 27th National Summer Crops Workshop, held at Rampur, Chitawan, 18-20 April 2013, Vol. I / Giri, Y.P.     Enhancing the productivity of mungbean through the breeding improvement in rainy and spring season in rice and maize based cropping system [printed text] / Rajendra Darai ; Surendra Yadav ; Gun Bahadur Gurung ; Nawa Raj Acharya ; Santosh Raj Tripathi, Author . - [s.d.] . - 58-67 p.

Enhancing the productivity of soybean through the breeding improvement in upland rainfed ecosystem / Rajendra Darai    

Public ISBD in Proceedings of the 27th National Summer Crops Workshop, held at Rampur, Chitawan, 18-20 April 2013, Vol. I / Giri, Y.P.     Title : Enhancing the productivity of soybean through the breeding improvement in upland rainfed ecosystem Material Type: printed text Authors: Rajendra Darai ; Surendra Yadav ; Gun Bahadur Gurung ; Rewati Raman Chaudhary ; Santosh Raj Tripathi, Author ; Tara bahadur Ghimire, Author Pagination: 43-57 p. Languages : English (eng) Keywords: soybean  ;  genotypes  conventional  breeding  high  yielding  wider  adaptation Abstract: Considering the importance of soybean crops, genotypes collected from ITT A, Nigeria, A VRDC Taiwan and local landraces were evaluated in observation screening nursery, coordina~ed varietal trial and participatory trial to compare the yield potential and insectdisease reaction under conventional breeding improvement works at NGLRP, Rampur and NORP, Nawalpur over the two years 2010 to 2011 with the aim to identify and recommend the high yielding, disease tolerant, early maturing bold seeded of soybean varieties suited for existing cropping system. Multi-location trial was carried out in RCB design with four replications and OBN in rod row while in pre-release varietal trial (PRVT) in none design. Mean yield performances of soybean cultivars over the years in Initial Evaluation Trial (Table 7) indicated that soybean cultivars AGS 87-4(1543 kg!ha), TGxl903-IF (1284 kg!ha), TGXJ740-2F (1174 kg/ha), GC8234GC-13(1173 kg/ha) and TGX1805-31F (1007 kg/ha) were the best yielder than the check Seti(284 kg!ha) and will be promoted in multi-location trials. Combined analysis of soybean cultivars over the years(20 I 0-20 II) and across the three location(Rampur, Surkhet and Nawalpur) in CVT determined that highly significant differences were observed in Genotype, Location, Year, Genotype X location but nonsignificant differences were in Genotype x Year. Overall performances of Soybean cultivars IangBeakong (2457 kg/ha), AGS 376(2401 kg!ha) and F-778817(2332 kg/ha)) were the highest mean yielder than the check Puja(2283 kg/ha). These lines has been promoted in participatory trial and also kept under the seed increase program both at the station and onfarm . Under pre-release varietal trial, the mean yield performances indicated that the cultivars TG X-311-23D (1149 kg/ha), PK 7394(1145 kg/ha) and Kavre(J005 kglha) were the best mean yield performer than the check Puja(732 kg/ha) across the location (Rampur and Surkhet) and over the years (20 I 0-20 II). These lines will be further verified and validated in the farmer's field condition and will be increased the seed on farm level to make a seed sufficiency and take up faster dissemination. At station, nucleus and breeder seed production is underway to maintain the purity and good quality seed for future use.
