elite plant
3.To set up an efficient plant regeneration system and select wheat genotypes suitable for tissue culture, factors affecting tissue culture were studied with the immature embryos of 24 elite wheat varieties under various conditions including four callus induction media and three differentiation media.
4.In order to get rice line with high yield and good quality, an early indica rice variety Zhou 903 with good quality was backgross with 4384, a rice line with high yield. Both phenotypic selection and CAPS (Cleaved amplified polymorphic sequence) marker assistant selection were conducted in segregated population to determine whether the plant has elite agronomic traits and TT site in Wx genotype.
