SUMMARY1 The effect of the parent crop husbandry in the case of oats has been traced upon the seed, its germination and early growth and yield. 2 The beneficial effects of seed grading by weight are again emphasised, but it has been demonstrated that such mass selection does not cause an improvement of the seed qualities in every respect. More subtle characteristics than weight have a predetermining effect. 3 The relationship between environmental conditions and panicle characters has been discussed. 4 In spring oats grown under Welsh conditions the importance of establishment, which can be roughly gauged by laboratory tests, is emphasised. Heating the seed samples appears to be a suitable method by which further information can be obtained as to the seed's vigour. 5 It seems that an index to yield is likely to be found in this direction. Seed vigour is correlated with yield. 6 Plant to plant variation is so wide between spaced individuals that little indication of the graminaceous plant's capabilities were discernible in seedling behaviour.
