The 7 indivichial selections are planted in a lilock surrounded by the increased plats, as indicated. The roguing of the increase plats and progeny rows is done the same as the first year. After careful inspection in the fall, 3 progeny rows are selected (indicated by "x"), and from these, 20 individual selections are made, as indicated. The remainder of the selected progeny rows are picked by themselves, ginned, and compared for wilt resistance, yield, and lint percentage, with the result that 2 are saved for the next year's increase plats, namely Nos. 2 -2 and 4-8. In the same manner the 20 individual selections are ginned and compared, and 10 finally saved for further work. /Vo 2-2 P/fOG£A/y /?ot^s ' ~^ ~^ ^ —o o- c>—. <^—<^—s-tS£ Plat lA/fG£ F/£ID £/?0/^ //VC/!'£/15£ /i/t7S AbS- 2 ^lA/O ^ Fig. 12.—( TUri Ytar.)
