Quality analysis of CMS-based pigeonpea hybrids

The experimental materials comprised of 1 02 pigeon pea hybrids (F,) along with check (BSMR 736) were derived by crossing three CMS-lines (ICPA 2043, ICPA 2047 and ICPA 2092 with 34 testers. The dal of 250 gm sun-dried F, seeds of hybrids and check was prepared, This dal was used to study cooking time (min), water absorption (gg"), dal recovery (%) and protein content (%). The analysis of variance for four quality traits studied was highly significant, indicating the presence of variation in the materials studied. The cooking time of dal had negative correlation with dal recovery while positive with protein content; whereas water absorption had negative correlation with protein content. The hybrid made between all the three malesterile lines with four male parents ICP 3525, ICP 3963, ICP 3374 and ICPL 201 06 took less time to cook than the check. The water absorption of dal by cooking (gg") for ICPA 2043-derived hybrids was slightly less than ICPA 2047- and ICPA 2092- derived hybrids. The mean dal recovery (%) for ICPA2047 - and ICPA2092-derived hybrids was 66.2 %. The hybrid ICPA2047 x ICP 3374 and ICPA 2092 x ICP 3374 (77.9 %) recorded significantly greater dal recovery (%) over the check BSMR 736 (69.37 %). The results of protein content among three CMS-based hybrids revealed that there was 20% protein present among three CMS-derived hybrids of pigeonpea. The hybrids ICPA2043 x BSMR 198, ICPA2043 x BSMR 175 and ICPA2043 x ICP 3407 possess significantly more protein (%) than the check (BSMR 736
