Response of mung (Vigna radiata) and mash (Vigna mungo) genotypes against Callosobruchus maculatus F. during storage

Zahid Iqbal, Shahid Hussain, Mhammad Ayub, Ishtiaq Hussain and Hasil Khan

Studies were conducted for the screening of mung and mash genotypes against Callosobruchus maculatus under laboratory conditions at NARC Islamabad during the year 2014. For this purpose No-choice and Free-choice tests were used. The parameters viz. adult emergence, damage to grains, weight losses, development period, per adult weight and number of eggs laid were recorded. Physiochemical analysis of grains was also done. In case of Mash, maximum damage and weight losses were 23.86 and 31.79% under No-choice test, and 23.45and 19.53% under Free-choice test were recorded. In case of mung grains, maximum damage and weight losses were 31.41 and 50.97%, respectively in No-choice test and those of 17.96 and 29.80%, respectively in Free-choice test. Different genotypes of mash and mung showed response differently under No-Choice and Free-Choice techniques. In case of mash, NARC-Mash-1 had the highest rating for all parameters under Free-choice test but lower under No-choice test. NCH-7-5 showed higher rating to all parameters in No-choice test but medium performance under Free-choice test. NCH-10-1 ranked on lower side for all parameters under Free-choice test but medium under No-choice tests. NCH-3-4 performed well under both types of tests. In case of mung, the response of different genotypes of mung was different for different parameters. The only genotype NCM-257-2 performed well on the basis of damage, weight losses, adult emergence and adult weight. The results of the present investigations revealed that none of the mash and mung genotype was completely resistant to C. maculatus. Size of the grains showed mix trend. However, the majority of the bold grains had more damage and eggs in both types of tests. In both, mash and mung, protein contents are negatively correlated with damage and adult emergence but positively correlated with developmental period. Fats have positive correlation with damage but the negative correlation with adult emergence and developmental period. Carbohydrate has a significant positive correlation with damage and adult emergence. Moisture has a positive correlation with damage and adult emergence in mash grains but the negative relation in mung. It has a negative effect on developmental period in both, mash and mung grains.
