Multple Disease Resistance<br />

While it is true that ascochyta blight is the major disease in the Mediterranean<br />

region, the presence of other diseases, such as fusarium wilt, stunt (pea leaf-roll<br />

virus) and botrytis grey mold has been reported from several countries in the<br />

region (Nene 1981).<br />

To identify lines with multiple disease resistance, the lines found resistant to<br />

wilt and stunt (pea leaf-roll virus) at ICRISAT Center were screened for resistance<br />

to blight during the 1980/81 season. The appearance of botrytis grey mold<br />

in epiphytotic form in Lahore (Pakistan) during the same season enabled a study<br />

of the reaction of entries in the CIABN and CIYT-W to this disease.<br />

The results of screening for wilt, stunt, botrytis grey mold and ascochyta blight<br />

are presented in Tab. 12. G 543, which is resistant to wilt anW stunt, showed<br />

tolerant rea.tion to blight. In addition, three wilt-resistant lines, GG 588, GG<br />

663 and GG 688 showed tolerant/resistant reaction to blight. Seven of the stuntresistant<br />

lines showed resistance to blight. Fcur blight-resistant lines showed<br />

resistance to grey mold under natural epiphytotic conditions in Pakistan.<br />
