Arabic to English Other Agriculture Description of variety of mango tree

This phrase is listed in a table outlining the qualities of different varieties of mango. Whole section of the table:
يتحمل قسوة المناخ /غير معاوم ويعطي إنتاجية جيدة / حجم الأشجار جيدة

It is within a scientific report on mangoes which goes into quite a lot of detail about propagation techniques.

I wondered if this word has something to do with annual/year, but I can't find it in any dictionaries. My other thought is that it might be a typo for غير مقاومas non-resistant would make sense as a benefit of one variety over another. Grateful for any thoughts. Thanks!
