Abstract:

The major objective of planting wheat in Pakistan is to get grains and then straw. Flag leaf contribution is reported over 40% in grain development. However, the greater flag leaf area development is not the sole reason to reflect greater mass for a variety. Our study showed that duration of the flag leaf area is also equally responsible to reflect maximum out put from a variety. To study variation in the grain yield of wheat varieties (Khyber 87, Suleman 96 and Nowshera, 96), the experiment was conducted at the Agronomy research farm of the NWFP Agricultural University, Peshawar during 1998-99. Sowing was done on Novembe22r, in rows 30 cm apart using three replications. Data was recorded on weekly basis for dry matter increment, leaf tiller number, leaf stem mass, flag leaf area, biomass and grain yield. Significant (p<0.05) differences were observed among the three varieties in yielding leaf and stem masses per tiller, flag leaf area, spike weight, grain weight and biomass as well as grain yield. However, leaf and tiller per plant and developmental rate per week of the three varieties were non-significant. The variation in grain weight per module was due to variation in flag leaf area and its duration. Nowshera 96 had prolonged anthesis duration and hence reflected higher grain weight as well as yield. Duration in flag leaf area rather than development made significant differences in yield of the three varieties.
