    Summary: We suggest and explore a matroidal version of the Brualdi-Ryser conjecture about Latin squares. We prove that any \(n\times n\) matrix, whose rows and columns are bases of a matroid, has an independent partial transversal of length \(\lceil2n/3\rceil\). We show that for any \(n\), there exists such a matrix with a maximal independent partial transversal of length at most \(n-1\).
