摘要: Fifteen Australian and exotic wheat varieties revealed genotypic differences in their patterns of root development drought tolerance. Earliness plant maturity, which accounted for 40 to go per cent the observed variation tolerance, appeared be by far most important characteristic tolerant genotypes, but there nevertheless a measurable relationship between some parameters development, water use efficiency The impact study this kind on problem breeding tolerance is briefly discussed.
