摘要

茎坏死病表现为节部暗褐色坏死部位，并引起叶柄最前端环剥脱落坏死。拉贾斯坦邦的Kota、Baran和Bundi区记录的干细胞坏死病发病率在8.5%至22.5%之间。块茎产量在等级上显著下降。在拉贾斯坦邦东南部，在超过75%的疾病严重程度下，观察到最大产量下降（63.16%）。

SURVEY AND ESTIMATION OF YIELD LOSS DUE TO STEM NECROSIS VIRUS OF POTATO GROWING AREAS OF SOUTH-EASTERN RAJASTHAN

Stem necrosis disease seemed as dim brunet necrotic parts at the nodes and caused girdling of the petiole foremost to leak dropping and necrosis. Stem necrosis disease ranged from 8.5 to 22.5 per cent was recorded in Kota, Baran and Bundi districts of Rajasthan. Significantly tuber yield reduction was recorded at grade wise. Maximum yield reductions (63.16%) were observed under more than 75% disease severity in Southern Eastern Rajasthan.
