Abstract: |
Four weeks old in t;itro plantlets and stem cuttings of potato cv. Cardinal were plallted under glasshouse with three plallf geomett)'· viz. 1 OxJO em. 1 5x I 5 em and 20x I 0 em to study the petformance of theie plallfing materials for pre-basic seed (PBS) production. The study was conducted in RCBD replicated thrice and the data analyzed with MSTAT-C. It was fotmd that in vitro plantlers produced five minitttbers per plant as compared to two from stem cuttings. However, the mean tuber size of PBS produced from stem cuttings was 8. 7 as against 2.8 g produced from in vitro plantlets. The plantlets planted with 10x10 em spacing yielded the highest number (294/nl) of PBS. Hence 10 x 10 em spacing is recommended for in vitro plantlets to maximize the mm1ber of PBS yield and for stem cuttings to maximize minituber yield as well as minimize the mean minituber size. |
