Studies on the root growth of wheat varieties

Twelve wheat varieties, C 306, C 591, NP 824, NP 846, NP 890, HD 1553, HD 1593, HD 1949, HD 1977, HD 1981, HD 2009 and HD 2122 were studied for their root characters. It was observed that there are potential genotypes which produce better lateral root system to support suitable shoot growth to give higher yield under moisture stress condition. Positive correlation of lateral root length with shoot growth and grain yield under moisture stress condition, indicate that such genotypes may be used for producing high yielding varieties for rainfed condition.
