摘要

鸽豆对内涝很敏感。在整个印度,大约25- 30%的鸽子豆面积容易受到过度水分胁迫。利用IPAC-79对63个种质/基因型进行了部分浸水和淹水大田条件下的耐涝性检测,为选育耐涝鸽豆品系提供依据。记录成活率、开花天数、单株种子产量和成熟期的数据。基因型ICARPP01、ICARPP02和ICARPP03被认为是有潜力的。ICARPP01产生最高的单株生物量(746.5g),荚果/株(924.6)和单株种子产量(151g)。ICARPP01基因型的花期最短(124天)和成熟期最短(197天),对照品种IPAC-79的花期最长(201天)和成熟期最长(255天)。

Development of waterlogging tolerant lines of pigeonpea for Eastern India
Pigeonpea is very sensitive to waterlogging. At pan India level, approximately 25-30 per cent area of pigeonpea is prone to excess moisture stress. Atotal of 63 germplasms/genotypes were evaluated along with IPAC-79 as the waterlogging tolerant check under controlled partial submergence condition and under waterlogged field condition for selection of waterlogging tolerant pigeonpea lines. Data were recorded for survivability, days to anthesis, per plant seed yield and maturity period. Pigeonpea genotypes ICARPP01, ICARPP02 and ICARPP03 were found promising. ICARPP01 produced highest biomass per plant (746.5g), pods/plant (924.6) and seed yield per plant (151g). The genotype ICARPP01 took minimum number of days for anthesis (124 days) and maturity (197days), whereas the check variety IPAC-79 recorded maximum number of days to anthesis (201 days) and maturity (255 days).
