Variation for 2n pollen production in clones of Solanum phureja Juz. and Buk



Variation for 2n pollen production in clones of Solanum phureja Juz. and Buk



Tag. Theoretical and Applied Genetics. Theoretische und Angewandte Genetik 59(2): 95-100



Frequency of unreduced pollen grains was estimated for 5 genotypes of S. phureja (2n = 24) growing in 3 environments; (E1) cool (7.2-13.3.degree. C) and (E2) warm (12.2-17.2.degree. C) growth chambers and (E3) field conditions. Highly variable frequencies were found, with genotype, environment and genotype .times. environment interaction as significant components of variance. The frequency of unreduced gametes for 2 additional genotypes was studied over time in 2 growth chamber environments (cool and warm). One genotype, characterized by mostly fused spindles at the 2nd meiotic division, expressed a high frequency of big pollen (BP) in both environments, whereas the second, characterized by fused, parallel and tripolar 2nd division spindles, increased in BP frequency over time in the cool chamber, but remained consistently low in the warm chamber. The identification of specific environmental components with general effect on the expression of unreduced gametes is not possible because of the large genotype .times. environment interaction component of variance. A genetic hypothesis based on incomplete penetrance and variable expressivity of a dominant gene is presented as an alternative to the currently accepted theory of control of parallel spindles by a single recessive gene.
