In: In: Central Tuber Crops Research Institute. Annual Progress Report 1983Summary: Se inicio un estudio basado en el analisis linea x probador. Las lineas usadas fueron H-2304, CI 700, CI 699 y CE 22 y los probadores fueron CE 380, CI 152, CI 572, CI 13 y M-4. En CI 699 se identifico una quimera con caracter variegado y se denomino CI 699 A. Se hicieron cruces entre las lineas isogenicas y otras 2 plantas normales y el mutante variegado. Todas las plantulas F1 fueron autofertilizadas y retrocruzadas con la planta quimera para estudios posteriores. Por otro lado, el cruce CI 699 x CI 572 mostro ramificacion y floracion simultaneas a la edad de 3 meses. (CIAT)Summary: A study based on line x tester analysis was initiated. Lines used were H-2304, CI 700, CI 699, and CE 22, and testers were CE 380, CI 152, CI 572, CI 13, and M-4. A chimera was identified in CI 699 showing variegated character and was designated as CI 699 A. Crosses were made between the isogenic lines and among 2 other normal plants and the variegated mutant. All F1 seedlings were selfed and backcrossed to the chimera plant for further studies. On the other hand, the cross CI 699 x CI 572 showed simultaneous branching and flowering at 3 mo. of age.
