2. The reciprocal crosses reported last year, made between inbreds with extreme differences in kernel size (Rice pop and Reid dent) again showed significant differences in early growth. These differences almost entirely disappeared by flowering time. The combined average days to tasseling and silking were 81 for the pop inbred and 66 for the dent. The two reciprocal crosses were 66 and 65. The crossed plants from the larger seeds flowered one day earlier. Differences in tillering also went with the larger initial growth, where the seed was produced by the non-tillering parent. The average number of tillers this year is dent 0, dent × pop 2.7, pop × dent 2.1 and pop 2.9.
