Respond Differently to Low Soil\r\nMoisture in Genotypes Contrasting for Drought Tolerance"^^ . "Water stress after flowering, one of the major factors limiting yields of pearl millet,\r\naffects both seed setting and grain filling and is a consequence of more/less\r\nwater used prior to anthesis. However, whether genotypes have different sensitivities\r\nfor seed setting and filling under drought, if exposed to similar stress intensity,\r\nis unclear. Experiments were conducted in two pairs of pearl millet\r\ngenotypes, that is, PRLT2/89-33 and H77/833-2, 863B and 841B, contrasting for\r\nterminal drought tolerance, and two genotypes, ICMR 01046 and ICMR 01029\r\n(IL-QTLs), introgressed with a terminal drought tolerance QTL from PRLT2/89-\r\n33 into H77/833-2. Total seed weight, panicle number, 100-seed weight, seed\r\nnumber and stover biomass were measured at different soil moistures and\r\nthroughout grain filling. Sensitive H77/833-2 had higher seed number and yield\r\nunder well-watered (WW) conditions than in PRLT2/89-33 and IL-QTLs. Upon\r\nincreases in water stress intensity, H77/833-2 suffered losses mostly in stover biomass\r\n(45 %) and seed number (60 %) at 0.3 FTSW whereas the biomass and seed\r\nnumber of PRLT2/89-33 decreased little (20 % and 25 %). The 100-seed weight\r\nof H77/833-2 decreased only 20 % under stress. Tolerant 863B also maintained a\r\nhigher seed number and biomass under water stress than 841B. Grain filling\r\nduration in PRLT2/89-33 and IL-QTLs was similar to that of H77/833-2 under\r\nWW conditions but lasted longer than in H77833-2 under water stress (WS).\r\nSimilarly, seed growth of 863B was longer than 841B under WS. It is concluded\r\nthat the higher seed yield of tolerant parents PRLT2/89-33 and 863B, and of ILQTLs\r\nunder WS was explained by the retention of a higher number of seeds than\r\nin sensitive lines, while the decrease in the 100-seed weight was proportionally\r\nless than the decrease in seed number. Phenotype with lesser number and larger\r\nsize of panicles and larger grain size, like genotypes PRLT2/89-33 and 863B, withstood\r\npost-anthesis water stress better. IL-QTL inherited part of these characteristics,\r\nindicating a role for the terminal drought QTL in maintaining larger seed\r\nnumber and higher 100-seed weight. The continuous stover biomass increase\r\nunder WW in H77/833-2, due to tillering, might indicate that tiller growth and\r\ngrains are in competition for resources after anthesis, and this may relate to the\r\nrelatively shorter grain-filling period."^^ .
