Unequal Seedling Survival Rates In Mixed Plantings of Sorghum Hybrids and Inbrcdsl

Abstract

In a recent publication Walker 1 has described an experiment in which he implies that inbred cotton seedlings are selectively weeded out compared with hybrids in multi-line strains at singling (thinning) by African hand labour they tend to leave the most vigorous plants. He uses this as evidence favoring the persistence of hybridity in multiline strains of cotton, for which he claims yield improvement.
