YIELD POTENTIAL OF LOCAL AND EXOTIC GERMPLASM WITH SPECIAL REFERENCE TO POWDERY MILDEW DISEASE IN PEA (PISUM SATIVUM L.) ZAHOOR AHMAD, ABDUL GHAFOOR, SH. MUHAMMAD IQBAL AND M. SAJJAD IQBAL*
Abstract: Pea germplasm consisting
of 69 pure-lines from diverse origin was evaluated under screen-house and field
conditions for 2 years for their resistance against powdery mildew and yield potential.
The genotypes viz., 10607, 10645, 10646, 88 P050-6-9, 88 P090-5-15 and 88 P090-5-22
although susceptible to powdery mildew but exhibited yield potential of varying
degrees. The genotypes, 10603, 10628, DMR 4, DMR 7 and DMR 20 were resistant to
powdery mildew, 10603 and 10628 from Pakistan were high yielding. It is suggested
to plant high yielding susceptible lines under disease free areas, whereas for
development of high yielding resistant cultivars, hybridization between resistant
and high yielding lines could be practiced.
