Association of photosynthesis of flag leaves with grain yield in pearl millet (Pennisetumglaucum (L.) R. Br.)

The grain yield of pearl millet has increased continuously in past decades through development hybrids and improved production practices. Elite inbred lines are crucial for innovating new germplasm/traits to break the plateau. Hence, 64 were evaluated assess extent genetic variability association among agronomic, physiological contributing traits. Analysis variance showed significant differences all traits indicating sufficient exploitation. preferred arid adaptation traits, early flowering high tillering associated with each other making them amenable simultaneous selection these two not yield. deriving ideotypes suitable adaptation, intensive background was suggested. In productive regions, plants having greater plant height, larger size leaves including flag leaf, panicle accommodate photosynthates desirable found be themselves current study. Though maximal photosynthetic efficiency, Fv/Fm significantly leaf length, width actual PSII efficiency (Y(II)), parameters did associate directly their effects confounded within morphological variation.
