New high yielding and disease resistant mungbean [Vigna radiata (L.) Wilczek] variety “NIFA Mung-19”

Abstract

Mungbean is an important kharif crop of Pakistan as well as the Khyber Pakhtunkhwa (KP) province. The overall yield of this crop is low and one of the main reasons is the poor genetic background of the existing mungbean varieties in the country. Mungbean varieties adapted to the growing conditions have purple hypocotyls, whereas mungbean varieties with green hypocotyls have an additional potential for sprouts production. In order to replenish the existing pool of mungbean varieties with better ones, a locally adapted mungbean variety "NM 92" and an exotic Mungbean Yellow Mosaic Virus (MYMV) susceptible variety "VC 1560D" were crossed (NM 92 x VC 1560D) in kharif 2004 at Nuclear Institute for Food and Agriculture (NIFA), Peshawar. Single plants selections for more pods plant -1 , semi erect growth, purple/green hypocotyls color, resistance to MYMV disease, and confirmation of breeding behavior of these traits were carried-out in F2 -F5 generations during 2006-2010. One of the recombinants designated as NFM-5-36-27 was selected on the basis of overall better performance with green hypocotyls color, and further evaluated in disease screening nurseries and various replicated yield trials. NFM-5-36-27 produced seed yield of 530 to 2076 kg ha -1 in replicated yield trials conducted during different years and locations compared with the check variety Ramzan (316 -1417 kg ha -1 ) with 38% to 68% increases in seed yield over Ramzan. In Mungbean National Uniform Yield Trial conducted in 2015 and 2017, NFM-5-36-27 produced higher seed yields of 725 and 996 kg ha -1 , respectively compared with national checks. NFM-5-36-27 has a future potential for mungbean sprouts production in the country due to its green hypocotyls color. NFM-5-36-27 was recommended as new mungbean commercial variety with the name "NIFA Mung -19 by the KP Provincial

The impact of insecticides and plant extracts on the suppression of insect vector (Bemisia tabaci) of Mungbean yellow mosaic virus (MYMV)

“…Different management strategies are opted by farmers and researchers to manage MYMV. However, use of resistant varieties is the most economical and environment-friendly management option for MYMV [ 4 , 14 , 20 , 21 ]. Management of whitefly through chemicals (pesticides, insecticides) can significantly reduce disease incidence.…”

Yellow Mosaic Disease (YMD) of Mungbean (Vigna radiata (L.) Wilczek): Current Status and Management Opportunities

“…The YMD resistance is generally assessed by the appearance of symptoms using a commonly accepted disease scoring scale (Khattak et al, 2008;Iqbal et al, 2011;Panduranga et al, 2011). However, while selecting any genotype as resistant, utmost care should be taken and any symptomless carrier should never be used in the YMV resistance breeding program as a resistance source.…”

“…There are abundance of reports stating absolute YMD resistance among certain mungbean lines, but most of them were poor yielder (Pathak and Jhamaria, 2004;Salam et al, 2009). Generally, the mungbean germplasm having good yield potential is reported susceptible to the YMD (Khattak et al, 2008;Akhtar et al, 2011). Success has been achieved via shuttle breeding program between the World Vegetable Center (AVRDC) and NIAB (Nuclear Institute for Agriculture and Biology-Pakistan), which has resulted in the development of several mungbean varieties having YMV resistant (AVRDC, 1995;Khattak et al, 2008).…”

New high yielding and disease tolerant wheat (Triticum aestivum L) variety NIFA AMAN-2017 for irrigated areas of Khyber Pakhtunkhwa

“…The current stagnancy in wheat yield can be overcome by introducing elite wheat germplasm. After testing the material under the local environment, either the promising genotypes can be used as improved varieties or they may be utilized in future breeding program for gene pyramiding in order to improve the agronomic traits of the existing varieties [15][16][17]. Moreover, with the passage of time, the recent varieties succumbed either due to adaptability problem [5] or new races of pathogen introduced [11].…”
