Flag leaves could help top off photosynthetic performance in rice

By | IRRI, News, Plant Science

The flag leaf is the last to emerge, indicating the transition from crop growth to grain production. Photosynthesis in this leaf provides the majority of the carbohydrates needed for grain filling—so it is the most important leaf for yield potential. A team of researchers found that some flag leaves of different varieties of rice transform light and carbon dioxide into carbohydrates better than others. This finding could potentially open new opportunities for breeding higher yielding rice varieties.

Making sense of a universe of corn genetics

By | Agriculture, News, Plant Science

Seed banks across the globe store and preserve the genetic diversity of millions of varieties of crops. This massive collection of genetic material ensures crop breeders access to a wealth of genetics with which to breed crops that yield better or resist stress and disease. But, with a world of corn genetics at their disposal, how do plant breeders know which varieties are worth studying and which ones aren’t?

Wheat disease common to South America jumps to Africa

By | Agriculture, News, Plant Health, Plant Science, Policy

A deadly wheat disease common to Asia and South America has been identified in Africa for the first time, raising fears of potential spread to wheat crops across the continent. Researchers say that the fast-acting and devastating fungal disease known as wheat blast was first spotted in Africa in the Zambian rainfed wheat production system in the 2017-2018 crop cycle.

Researchers uncover novel mechanism of weak apical dominance in rice

By | Agriculture, News

Cereal crops exhibit two distinct types of branching which are the important determinants of crop yield. Crops such as maize and sorghum produce only one culm to reduce competition among sinks and increase the productivity of the main culm, thus exhibiting enhanced apical dominance. Rice and wheat produce multiple tillers (a type of branch that is similar in shape and height to the main culm) and exhibit weakened apical dominance.

Comprehensive and systematic evaluation of ~22,000 wheat accessions

By | Agriculture, News

The national wheat improvement program in India has contributed significantly toward achieving food security since the advent of the green revolution in the 1960s. However, for the sustainable wheat production in this era of climate change, high yielding thermo-tolerant varieties with durable disease resistance, and with the capacity to produce more with less of water and fertilizers are urgently needed. Recently, the first study conducted on comprehensive and systematic evaluation of ~22,000 accessions of wheat was published.
