Abstract: Breeding for maturity duration is of prime importance to adjust maximum number of crops in crop rotation per unit time. CIMMYT PAK, short duration white maize Open Pollinated Variety (OPV), was introduced in Pakistan through International Maize and Wheat Improvement Center (CIMMYT). The variety was successfully acclimatized and tested for its yield potential as well as maturity duration in Station and National Uniform Maize Yield Trials (NUMYT). It gave 5.9% higher yield than check variety in NUMYT. It matures in 85-90 days while maturity duration of the check variety is 110-115 days. A stable behavior was shown by the variety against stalk rot caused by Fusarium moniliform as it was found moderately resistant for both of the seasons. Agronomic investigations revealed that the variety should be planted on ridges with 30″ row to row and 8″ plant to plant distance to obtain maximum grain yield for both Spring and Kharif seasons. Incorporation of this variety in local see system will not only boost up the provision of certified seed but also will enhance the production of maize crop. Lodging resistance and stay green character in addition to short maturity make the variety highly acceptable to the farming community.
