46. In crop improvement programme , haploids are important as they [1989] (a) require one half of nutrients (b) are helpful in the study of meiosis (c) grow better under adverse conditions (d) form perfect homozygous
Option D.In crop improvement programme, haploids are important because they form perfect homozygous lines. Homozygous are the pure line selection plants resulting from self pollination. In this way, considerable homozygosity is obtained. Haploids are those plants which possess a gametophytic number of chromosomes. Haploids are used in plant breeding, especially for the production of homozygous plants and in their studies in the detection of mutation
