Screening rice genotypes for tolerance to alkalinity and zinc deficiency

Summary A preliminary investigation on the inheritance of tolerance to Zn deficiency and the inter-relationship of tolerances to Zn deficiency and alkalinity was made. Three generations of 2 crosses involving parents tolerant (IR20 and IR30) and sensitive (E425) to Zn stress were screened in IRRI concrete beds. One hundred genotypes (varieties and breeding lines) were screened for injury from alkalimity and Zn deficiency. The results of this experiment and earlier mass screening experiments were subjected to association analyses. The results in general indicated that tolerance to different mineral stresses behave nearly independently. The frequency distribution of ratings for 3 generations indicated that the trait tolerance to Zn deficiency is under polygenic control showing continuous variation and transgression in F₂. Tolerance seems to be dominant. The heritability varied between crosses.
