Abstract

An experiment was conducted using five different wheat genotypes to determine their resistance to Sitotroga cerealella (L.) at Chaudhary Charan Singh Haryana Agricultural University, Hisar during the year 2018-2020. The experiment was carried out in Completely Randomized Design (CRD) with three replications in a control temperature of 29±2˚C with 65±5% relative humidity. The cultures were maintained in glass jars of 1 kg capacity containing the wheat grains and 25 adults of S. cerealella were released in these jars, separately. The results were evaluated by calculation of susceptibility index, percent grains damaged and percent weight loss of wheat grains against the infestation of S. cerealella. Among all the genotypes percent grains damaged (52.91%), percent weight loss (21.75%) and was found to be ‘highly susceptible’ genotype, while the lowest percent damaged grains (25.25%) and weight loss (8.64%) were recorded in genotype HPBW 1 and was found the ‘susceptible’ genotype against the infestation of pest, while all the remaining genotypes were intermediary to the pest attack.

小麦谷曲菌对不同小麦品种数量损失的评价

2018-2020年，在印度希萨尔乔杜里·查兰·辛格哈里亚纳邦农业大学对5种不同基因型小麦进行了抗性试验。试验采用完全随机设计(CRD)， 3个重复，对照温度29±2℃，相对湿度65±5%。将培养物保存在容量为1 kg的装小麦粒的玻璃罐中，并将25只成虫分别放入罐中。通过计算小麦对小麦黑穗病的敏感性指数、籽粒受损率和籽粒失重率来评价试验结果。在所有基因型中，籽粒受损率(52.91%)和失重率(21.75%)为“高度易感”基因型，而HPBW 1基因型的籽粒受损率(25.25%)和失重率(8.64%)最低，为“易感”基因型，其余基因型均为害虫侵袭的中介基因型。
