Hybridisation and Description of the Trait-based and Empirical Selection Programs

摘要

PARENTS SELECTED on the basis of the three main physiological traits (IE, W and HI) were used in a crossing program that was implemented at four ideations in India and one location in Australia, Details of the crossing program are given below. There were four crosses at each centre. There were originally intended to be three common crosses and one cross involving the best locally-adapted line by a parent possessing the drought trait most deficient in the adapted line. For example, in the QDPI program, Streeton with good HI and T was crossed with a high TE parent, ICGV 86031.
